INSTALLATION

BATTERY CHARGER USER’S MANUAL PART-1:INSTALLATION
MCEnPC23-REV.2.4 Page 2
1. INTRODUCTION
This user manual contains important technical instructions to be followed by qualified personnel responsible for the installation,
start-up, maintenance operations and knowledgeable on batteries and safety requirements/precautions involved. We recommend
this manual to be read attentively to ensure safe and reliable operation of this equipment.
Should you require any assistance, please call our service department.
2. IMPORTANT SAFETY INSTRUCTIONS
Keep these instructions in a safe place: this manual contains important safety and operating instructions
AC and DC currents are present in this system even with indicators and breakers are in “OFF” position.
Before performing any maintenance on this system, make sure that the battery and the AC power are disconnected.
Only experienced and qualified personnel must perform maintenance.
Electrostatic sensitive components are used in this equipment. Proper ESD (electrostatic discharge) procedures must be
followed to prevent any severe damage to electronic components.
Working in the vicinity of Lead Acid or Nickel Cadmium batteries is dangerous: batteries generate explosive gases
during normal operation. Therefore, never smoke or allow an open spark or flame in the vicinity of the battery or
engine.
To reduce risk of battery explosion, follow these instructions and those on the battery.
Never charge a frozen battery.
Do not expose charger/rectifier to rain or snow unless it has the appropriate NEMA/IP rating.
Do not install or operate chargers if they have been dropped or damaged.
Refer to your local/national electrical code for installation
3. STORAGE / MAINTENANCE DURING STORAGE
If the charger/rectifier has to be stored before commissioning, it should be stored in a dry place, in the ambient temperature
within –40oF to 185oF (-40oC to 85oC), not exposed to direct sunlight, on the same pallet, protected against moisture, dust, dirt
and damage. Do not use the charger/rectifier as a stocking shelf.
Remember that storing the charger/rectifier for a long period (5 years or more) can deteriorate performance of the filter
capacitors and can cause also contact oxidation for relays, breakers, contactors… Filter capacitors shall be replaced after storing
the charger/rectifier 5 years or more.
Please contact the manufacturer for capacitor specifications and installation.
Warning
For batteries and other accessories (UPS…), please refer to the specific manufacturer indications for battery periodical
recharge and powering up procedure after storage.
4. PLACEMENT AND INSTALLATION
FOR INSTALLATION, PLEASE REFER TO NATIONAL AND/OR LOCAL ELECTRICAL CODES.
Chargers/rectifiers are very heavy. To prevent personal injury or equipment damage, use appropriate lifting devices and execute
extreme care while handling the equipment.
The following instructions are very important to satisfactory operation. Changing the settings voids the warranty.

BATTERY CHARGER USER’S MANUAL PART-1:INSTALLATION
MCEnPC23-REV.2.4 Page 3
Warning
Battery application and maintenance:
Your battery is a crucial back up for your critical application. Special care and appropriate safety and maintenance
procedures must be implemented.
Please refer to the battery manufacturer instructions and the applicable battery installation, maintenance, testing and
replacement standards for stationary application in order to optimize the life of the battery as well as to determine when
the battery should be replaced.
VRLA case (Lead Acid battery incorrectly called "maintenance free"): As this battery is sealed not allowing visual
inspection or water addition, dry out and thermal runaway inside the battery can happen resulting to an unpredictable
failure occurrence. Great care in installation, maintenance, testing and replacement is required to insure availability of
backup power.
The manufacturer instruction, your local standards and the following standards can be your guide to help to apply
proper procedures: (other standards may apply).
IEEE484: IEEE Recommended Practice for Installation Design and Installation of Vented Lead-Acid Batteries for
Stationary Applications.
IEEE450: IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for
Stationary applications.
IEEE1188: IEEE Recommended Practice for Maintenance, Testing, and Replacement of Valve-Regulated Lead-Acid
(VRLA) Batteries for Stationary Applications.
IEEE1106: IEEE Recommended Practice for Installation, Maintenance, Testing and Replacement of Vented Nickel-
Cadmium Batteries for Stationary Applications.
5. VENTILATION AND COOLING
The rectifier/charger is rated to better perform within 18F (–10C) and 122F (+50C) temperature range.
To calculate the required air displacement (exchange) volume, please use the following equation:

V= air flow: [cubic meter/hour]
BTU: Total dissipated heat
Tr: Maximum allowed room temperature [K] {i.e. 50C = 323K]
Tk= Temperature of input cooling air
To= 273 K
H= Altitude [km]
WARNING!
Avoid placing the system in direct sunlight
The adequate ventilation and safe access require that the following clearances are respected:
3 in. (10 cm) on the sides and top;
3 feet (1 meter) in front of the unit;
DO NOT INSTALL OVER COMBUSTIBLE SURFACES;
Should seismic conditions require a more secure installation the unit can be bolted to the floor. Four (4) holes are provided for
this purpose.

BATTERY CHARGER USER’S MANUAL PART-1:INSTALLATION
MCEnPC23-REV.2.4 Page 4
6. ELECTRICAL CONNECTIONS AND WIRING
Before connecting the battery charger ensure that:
The battery is disconnected (if applicable)
The circuit breakers are OFF
The relays, fuses and circuit boards are installed
The unit is wired in accordance with the instructions (refer to the wiring connections and electrical diagram)
The appropriate cable sizes are very important. The nameplate provides the essential information regarding the input and output
voltages and currents.
Use a branch feeder (circuit breaker or fused disconnect switch), sized to the maximum input current.
Refer to your Local or National Electrical Code for LOCKOUT, WIRE GAUGE and GROUNDING instructions.
The ampacity of the power cables must be sized to the maximal correspondent current.
Correct voltage and polarity are of critical importance. Check all connections for tightness and polarity. Connect battery (if
applicable to the output terminals observing its polarity.
7. POWERING UP
After the installation of all wires is completed and has been double checked, the unit may be powered up as follow:
Before connecting a load to a charger, compare the critical characteristics of the load against those of the
charger (i.e. measure ripple, line-neutral voltage, positive-neutral voltage).
Keep a log of the values entered for VFLOAT and VEQUALIZE values entered, alarm messages, alarm and SCR
blinking LEDs, etc.
All input and output breakers must be in ”OFF” position
Apply power to the equipment from a source
Turn on AC breaker (if supplied) (”ON” position)
Wait 30 seconds
Turn on DC breaker (if supplied) (”ON” position)
Green LED must light up
Wait 5 seconds until the LCD display will show the system’s output voltage and status
The system soft starts by rising the output current and the voltage
If an adjustment or calibration of the unit is necessary, refer to the field programming section for more information.
8. SYSTEM POWERING OFF PROCEDURE
Open the DC breaker (if supplied) (OFF position);
Open the source panel’s AC breaker (if supplied) (OFF position);
Open the AC breaker feeding the powering the battery charger from external distribution panel;
If work inside a unit has to be performed, wait 5 minutes to let the filter capacitors to discharge or use
bleeding resistors of the correct rating to discharge the capacitors;
After following all previous steps, the battery charger can be considered de-energized.
