1Introduction
1.1 General
The Vertiv™ NetSure™ Model V200E50 DC Power Retrofit is a power solution comprising a Mounting Frame that allows two (2) new-
generation NetSure Rectifiers (Model R48-5800e, Spec. No. 1R485800e), to be installed in the NetSure Model 1231V1, Spec. No.
582121300 Power Bay. The Retrofit replaces one V200E50 Power Conversion Unit (PCU), and can operate with or without the original
PCUs in the same system.
The Vertiv™ NetSure™ Model V200E50 DC Power Retrofit provides load power, battery float current, and battery recharge current
during normal operating conditions. Each rectifier in the Retrofit incorporates a constant power design. This means that, within the
normal operating ambient temperature range, the maximum output power available is a constant 11,600W per Retrofit. Within the
normal temperature range, the rectifiers operate in one of three modes, depending upon load demands. Transition between modes is
completely automatic.
•Constant Voltage Mode: For any initial output voltage setting from 47 to 58 volts, output voltage remains constant regardless
of load. This is the normal operating condition, in which loads are being supplied and batteries are float charged. Rectifiers
operate in the Constant Voltage Mode unless load increases to the point where the product of load current and output
voltage is approximately 11,600W per V200 Retrofit.
•Constant Power Mode: As load increases above approximately 11,600W per V200 Retrofit (non-adjustable), output current
continues to increase, but output voltage decreases as required to maintain constant output power. Rectifiers operate in the
Constant Power Mode unless load continues to increase to the point where the current limit setting is reached.
•Constant Current Mode: If load increases to the current limit setting, output voltage decreases linearly to maintain output
current at the current limit setting.

b) Full Rated Load: -40°C to +45°C (-40°F to +113°F)
c) Reduced Load: +45°C to +65°C (+113°F to +149°F). Refer to Figure 2.4.
Storage Ambient Temperature Range: -40°C to +80°C (-40°F to +176°F).
Humidity: This system is capable of operating in an ambient relative humidity range of 0% to 90%, non-condensing.
Altitude: 2000 m (6560 ft) at full power (power limited for heights above 2000 m).
Ventilation Requirements: When equipped with V200 Retrofits, a VPS Power Bay must be mounted so ventilating openings are not
blocked and temperature of the air entering the cabinet does not exceed the Operating Ambient Temperature Range stated
previously.
In addition, the distance from the rear of a VPS Power Bay to a wall or other solid structure must not be less than 15 inches. This will
assure proper air flow through the V200 Retrofits.

NOTE! This level of protection is a widely used standard for telecommunications power equipment. As with all such
equipment, it is the end user's responsibility to provide an adequately sized Surge Suppression Device at the commercial
power service entrance of the building that reduces all incoming surges to levels below the classes/categories stated for the
equipment.
Compliance Information
a) Safety: The rectifiers have been recognized to meet the UL/EN/IEC 60950-2000 safety standard and are CE marked.
b) RoHS: The rectifiers are RoHS compliant, 5/6.
2.4 Standard Features
Type of Power Conversion Circuit: High frequency.
Float Charging Output Mode: This operating parameter is identical in systems equipped with the V200E50 Retrofits and systems
equipped with the original V200E50 Power Conversion Units (PCUs). Refer to System Application Guide SAG582121300 for a
complete description.
Test/Equalize Charging Output Mode: This operating parameter is identical in systems equipped with the V200E50 Retrofits and
systems equipped with the original V200E50 Power Conversion Units (PCUs). Refer to System Application Guide SAG582121300 for
a complete description.
Output Mode (Float or Test/Equalize) Selection: This operating parameter is identical in systems equipped with the V200E50
Retrofits and systems equipped with the original V200E50 Power Conversion Units (PCUs). Refer to System Application Guide
SAG582121300 for a complete description.
Input Protection:
a) Input Fusing: Input fusing is provided in each rectifier. This fusing is not customer replaceable.
b) Input Over-Voltage Protection: A rectifier shuts down and its protection indicator (yellow) illuminates when the input voltage
increases to above 530VAC. This condition is reported to the system MCA, which issues an AC Fail alarm. When the AC
input voltage decreases to within design parameters, the rectifier automatically restarts.
c) Input Under-Voltage Protection: A rectifier’s protection indicator (yellow) illuminates when the input voltage decreases to
below 256VAC. The rectifier shuts down and the system MCA issues an AC Fail alarm if the input voltage decreases to below
approximately 248VAC. When the AC input voltage increases to within design parameters, the rectifier automatically restarts.
Output Protection:
a) Current Limiting: The maximum current delivered by the system can be programmed from 10% to 110% of total system
capacity. The system MCA automatically adjusts the current limit circuit on each V200 Retrofit so that this value is not
exceeded. If a V200 Retrofit fails, the MCA automatically resets current limit point of each remaining V200 Retrofit to
maintain this value. The MCA also insures that the current limit circuit of each remaining V200 Retrofit is not set above 110%
of its capacity. The default current limit setting is the sum of the output ratings of each installed V200 Retrofit. If a V200
Retrofit is added to the system, the system current limit is automatically increased by the rating of the new V200 Retrofit and
the new current limit value is displayed.
The current limiting point can be adjusted without removing a V200 Retrofit. One adjustment changes the setting of all
V200 Retrofits.
The current limit is factory set at 100% of rated full load, unless otherwise specified.

b) Thermal Power Limiting: Each rectifier continuously monitors the ambient temperature surrounding the power conversion
circuit. If this temperature for any reason (such as a high ambient temperature) increases above approximately +45°C
(+113°F), the Rectifier will not shut down. Rather, the rectifier will limit its maximum output power to maintain the temperature
of the power conversion circuit within design parameters. Operation between +45°C (+113°F) and +65°C (149°F) will result in
the output power being decreased. Full power capability is restored when the temperature decreases to below approximately
+45°C (+113°F). Figure 2.4 illustrates typical operating parameters.
WARNING! The module is rated for continuous operation at full output power up to +45°C (+113°F). Operation between
+45°C (+113°F) and +65°C (149°F) will result in output power decreasing. Operation above +65°C (+149°F) is considered
abnormal and should be used on a temporary1basis only.
1Temporary Operation at Abnormal Temperature: Temporary operation refers to a period of not more than eight
consecutive hours per day, and a total of not more than 15 days in a year. (This refers to a total of 120 hours in any given
year, but no more than 15 occurrences in that one year period.)
Figure 2.4 Typical Thermal Power Limit Curve
c) Output Fusing: Output fusing is provided in each Rectifier. If a fuse opens, local and remote Rectifier Fail Alarms activate.
This fusing is not customer replaceable.
d) High Voltage Shutdown (Each Rectifier):
1. Selective: If rectifier output voltage exceeds an adjustable preset value and is delivering more than 10% of its rated
current, the rectifier shuts down.
After approximately 6 seconds, the rectifier automatically restarts. If rectifier output voltage again exceeds the high
voltage shutdown value within 5 minutes, the rectifier shuts down and locks out. Manual restart is then required (by
turning AC power off or removing the rectifier, then reapplying AC power or reinserting the rectifier). If the rectifier does
not experience a high voltage condition within the 5 minute time period, the restart circuit is reset.
Only the rectifier causing the high voltage condition shuts down.
Setpoint is adjustable from 56.00 to 59.50 volts DC. Factory set at 57.50 volts, unless otherwise specified. One
adjustment at the system MCA changes the setting of all Rectifiers.

2. Backup: If rectifier output voltage exceeds a second (non-adjustable) value, the rectifier shuts down and locks out
regardless of load. Manual restart is then required. The backup HVSD setpoint is 59.5V (within the range of 58.5 to
60V).
Load Sharing (via system MCA): The MCA load sharing feature automatically balances the load to within ±2% of the rectifier’s rated
output current. If the MCA's load sharing feature is disabled for any reason, advanced digital active load sharing technology in each
Rectifier balances the load. The MCA's load sharing feature is disabled whenever the system is in current limit, the system is
delivering more than 97% capacity, or the system is delivering less than 3% capacity.
NOTE! For optimal load sharing between the V200 Retrofits and legacy V200 PCUs, MCA version 4.2.0 or newer is required.
With earlier MCA versions, system functionality is maintained; however, load sharing will not be proportional.
Startup Time: Each rectifier has two startup modes:
a) Normal Soft Start Time: The duration from the time when the Rectifier is powered on to the time when the Rectifier provides
output voltage is <8s.
b) Current Walk-In: The rise time of the Rectifier output voltage is >8s at 90% of the rated load, and the maximum time is 90s at
100% of the rated load.
Hot Swappable: Each rectifier is designed to be plug-and-play. The rectifier can be inserted or removed from a live DC power system
with no damage. When the rectifier is plugged into the system, the system output voltage will not be affected.
NOTE! The Retrofit Mounting Frame CANNOT be installed in or removed from the Power Bay unless all Rectifiers are first
removed from the Mounting Frame. Doing so will defeat the precharge circuit in the rectifiers and cause arching and pitting
on the DC power connector!
Cooling: Each rectifier contains two fans for front-to-back forced convection cooling.
Fan Control: When the PFC bus voltage is within a normal range, the built-in processor adjusts the fan’s speed according to the
Rectifier’s internal temperature and output current. For example, a higher temperature or output current will increase the fan speed.
Above 45°C at full load, the fan operates at full speed. When the PFC bus voltage is abnormal, such as very low bus voltage, the fan
turns off.
Fan Fault Protection: An alarm will be generated upon a fan fault. In such cases, the fault indicator (red) on the Rectifier front panel
will flash and the Rectifier will also inhibit its output. Auto-recovery is enabled upon the clearing of the corresponding fault.
Communication Failure: A rectifier’s protection indicator (yellow) will begin flashing should it experience a communication failure.
The failure information will be reported to the Controller and the Controller will process the failure accordingly. During a
communication failure, in order to protect the battery, rectifier output voltage will automatically adjusted to a default value of 53.5 V.
The rectifier will revert to normal operation once normal communication is restored.
Imbalance of Rectifier Output Current: When the output current of a rectifier in a DC power system is unbalanced, the rectifier having
the unbalanced output current will be identified automatically and its protection indicator (yellow) will illuminate.
The failure information will be reported to the Controller and the Controller will process the failure accordingly.
Paralleling: A Power System equipped with V200 Retrofits may be connected in parallel with any rectifier of the same polarity and
adjusted to the same output voltage.
Emergency Shutdown and Fire Alarm Disconnect: The rectifiers can be inhibited by application of an external ground signal to the
system. Manual restart is required. This option is selectable on the bays only and not the retrofit shelf.
NOTE! The cooling fans will continue to operate if AC input voltage is present.

3.1 Safety Statement
DANGER! INSTALLERS MUST FOLLOW APPROVED SAFETY PROCEDURES. Hazardous AC and DC power sources are
connected to, and are present within, the Power System. Following this installation procedure will minimize the possibility of
personal injury or equipment damage. Refer to the documentation provided with your Power System for any installation or
maintenance procedures beyond the scope of this upgrade procedure.
The Vertiv™ NetSure™ Model V200E50 DC Power Retrofit is designed to mount in a Model 1231V1, Spec. No. 582121300 Power Bay.
Installation in any other Power System should not be attempted.
Installation consists of removing one existing V200E50 Power Conversion Unit (PCU) or blank cover panel from the Power Bay,
installing the V200 Retrofit Mounting Frame in the Power Bay, and installing the two furnished NetSure™ R48-5800e Rectifiers in the
Mounting Frame.
The Vertiv™ NetSure™ Model V200E50 DC Power Retrofit can be installed while the Power System is in service. Before starting,
ensure that all AC input and DC output connections to the Power Bay are intact. No changes or adjustments are required for these
connections when installing the Vertiv™ NetSure™ Model V200E50 DC Power Retrofit. All wiring and grounding should follow the
current edition of the National Electrical Code and applicable local codes.
Performing this upgrade procedure may activate external alarms. Do one of the following. If possible, disable these alarms. If these
alarms cannot be easily disabled, notify the appropriate personnel to disregard any future alarms associated with this system while
this procedure is being performed.
Follow the procedures below to replace one or more existing V200E50 Power Conversion Units (Rectifiers) with the Vertiv™ NetSure™

simultaneously.
3.3 Remove Style Strips from Power Bay
Procedure
1. Remove the two style strips from the front left and right edges of the VPS Power Bay being upgraded. These conceal the
mounting hardware. The style strips are secured at the bottom with a captive fastener, and at the top with a pin that passes
through a hole in the style strip. To remove the style strip, loosen the captive fastener at the bottom, and slide the bottom of
the style strip out and up.
3.4 Remove the Power Conversion Unit (PCU) or Blank Cover Panel
Procedure
1. If the mounting position in the Power Bay has a cover panel rather than a V200 PCU, remove the cover panel by first
removing the four screws that secure it. Then skip steps 2 and 3.
NOTE!
In the next step, the OUTPUT SWITCH has a mechanical interlock that prevents a PCU from being plugged into or
pulled out of a bay with the device in the "on" position.
CAUTION! In a system with NO redundant Rectifier, battery must have sufficient reserve to power the load(s) while the
Rectifier is removed.
2. On the PCU to be removed, place the Standby/Operate switch to the "standby" position, then the OUTPUT SWITCH to the 0
"off" position. See Figure 3.1 for locations.
Figure 3.1 Switch Locations
DANGER! In the next step, use two people to remove a PCU. A PCU weighs approximately 80 lbs.

NOTE! In the next step, a safety latch is present on each PCU that prevents the PCU from inadvertently being removed
completely from the Power Bay.
3. Loosen the captive fasteners on the front of the PCU to be removed. Use the handles provided on the front of the PCU, and
pull the PCU out until it is stopped by a safety latch located on the right-hand side panel of the PCU. Refer to Figure 3.2 for
latch and release location. Depress and hold the latch release, and remove the PCU from the Power Bay. Support the bottom
of the PCU as you pull it out.

3.5 Install the Mounting Frame
The Retrofit Mounting Frame CANNOT be installed in the Power Bay unless all Rectifiers are first removed from the Mounting
Frame. Doing so will defeat the precharge circuit in the rectifiers and cause arching and pitting on the DC power connector!
Checking the Power Bay’s Rectifier AC/Data Connector in Older Style Bays
Identifying Older Style Bays
1. Older style bays have Rectifier AC/Data connectors that do not have springs as shown in Figure 3.3. In bays that have
Rectifier AC/Data connectors without springs, perform the following procedure.

Check Procedure (Older Style Bays Only)
1. With the PCU removed, use a quality wooden carpenter’s ruler or other non-conductive rule. Place the measuring device
directly against the unpainted bracket holding the AC/Data connector. Take two measurements, one on the bottom of
connector directly next to the bolt through the black ac housing, and note the distance to the front outside of the left side
panel. Take second measurement on the top of the AC/Data connector. Both must measure 15-5/16” + 1/16” or -1/16”
tolerance. See Figure 3.4.
Figure 3.4 Taking Measurements
2. Pay close attention to the measurements, they must be within 15-1/4” to 15-3/8”. If a measurement is greater than 15-3/8” or
less than 15-1/4”, adjustment is required (see next procedure).
Adjustment Procedure (Older Style Bays Only, if required)
1. When adjustment of the PCU slot is required, it is recommended to remove the PCU below the slot which requires
adjustment. This allows the AC/Data connector to be moved as required to properly set the 15-5/16” measurements.
NOTE! The MCA will alarm with the removal of any PCU, so be aware Minor and Major alarms could be generated during this
process.
2. In the PCU slot to be adjusted, remove the rear sheet metal panel on the rear of bay and locate the two Philips 1/4” self
tapping screws at the bottom of panel, which holds the AC connector. Loosen these screws. See Figure 3.5.
3. Directly to the right of the two Philips screws is a single 1/4” inch hex bolt which also must be loosened for lower adjustment.
See Figure 3.5.
