1. Introduction
1.1 System Introduction
This rack-mounted UPS can be installed into a 19” rack, placed together with
all your networking equipment, Hub Switches and Remote Routers in a single
computer equipment room so that all devices are protected by the UPS; the setup
has a fashionable look, too.
Our rack-mounted UPS is a state-of-the-art, ideal, on-line and fully
uninterrupted power supply system. Sine-wave output accompanied with bypass
switching provides a reliable and high quality AC power source. The wide range of
application covers computer equipment, communication systems and industrial
automation facilities. Thanks to the On-line design, the device provides functions
such as voltage regulation, mains filtration and frequency drift prevention in
normal operation. During a power outage, the stand-by battery pack will switch-in
to maintain a sustained power supply. Under an overload or inverter failure, the
UPS device will automatically switch-over to bypass mode for the system to be
powered by the Power Mains; when the overload condition is eliminated, the
system will automatically switch back to inverter mode. All the switching over
takes place within 4ms, so that your equipment operates continuously without any
interruption.

1.3 Safety Precautions
Detailed safety regulations
All the safety regulations described in this manual shall be strictly observed during
the installation and maintenance of the UPS and battery assembly.
Note:
The UPS unit contains a battery pack which is very heavy; in order to prevent
the rack from falling over, the UPS unit shall be positioned as low as possible
in the rack.
Connect the UPS to a socket furnished with a circuit breaker or fuse
protection and capable of sustaining a current of at least 30A.
To ensure normal operation, this device shall not be used to power electric
drills, vacuum cleaners or laser printers, for which transient starting current is
high.
The UPS contains high voltage; in case of any problem, please consult a
professional or contact the service center for assistance to prevent any injury.
The UPS carries the power of the battery pack; the output may carry an
output voltage even if the UPS is disconnected from the power mains.
The rated voltage of the internal battery pack is 144VDC.
Grounding wire – a non-loading PVC wire that is green or green with narrow
yellow strips.
The grounding wire depicted above denotes the connection wire that
connects the metal casing of the device to the ground.
The maintenance and replacement of the battery pack shall be carried out by
a trained UPS professional. No other personnel shall be allowed to
manipulate the UPS.
When replacing the battery, observe the principle of consistency in the
quantity, brand and model number. In case of any problem resulting from the
customer using batteries other than that approved, the customer shall be held
responsible.
It is strictly forbidden to expose the battery or battery pack to fire, or
explosion and injury may occur.
Never dismantle or damage the battery arbitrarily, or else the battery fluid
may spill out. The battery fluid is highly corrosive; it may cause severe injury
to the skin and eyes if touched.
Shorting electrodes of the battery will cause risks of high voltage and high
electric current.
Placing magnetic objects upon the UPS may cause data loss or damage.
In order to secure safe and continued operation, the
user must observe the regulations for using the UPS
correctly and the following precautions:
Do NOT open the outer cover of the UPS.
Avoid placing the UPS in an environment of high temperature and humidity.
Do NOT pour any liquid or poke any object into the UPS.
Do keep the venting slots in the front, rear and sides unclogged.
Avoid exposing the UPS to direct sunshine and avoid placing it near a heat
source.
High-voltage Risks:
Note: High-voltage will be present between a battery electrode and the
ground if the battery circuitry and input voltage are not isolated. Check any
electrode for high-voltage before touching it.
Note: Even if the UPS is disconnected from the power mains, internal parts of
the UPS are still connected to the battery pack. Therefore a potential risk
exists. Make sure the battery jumpers are disconnected before performing
any maintenance or repair.
Warning: Batteries will age with the time. When aging occurs, consult
professionals for regular replacement or treatment, or the battery fluid may
leak, causing fire or other hazards. We suggest regular maintenance to
check the batteries once a year.
Note: Batteries tend to age and gradually lose their capacity when used at the
normal temperature (approx. 25°C).A normal lifespan is 2-3 years. If batteries are
used with frequent cycles of charging and discharging, the lifespan will be further
shortened.

2.3 Wiring Method
(1) At least 10AWG (soft) or 22mm² (hard) wires shall be used for the input
and output wires.
(2) Wiring the input: In case of 3-phase 4-wire 208/120V power system (with
R, S, T, N, and G wires) taking any 2 phases as the power input, the
Neutral wire (N) must be connected too.
2.4 ON and OFF Operation of the Unit
(1) After verifying correct wiring to the Power Mains, press the “On/Mute”
button and the load indicator on the panel lights up. Check indicators one
by one. A few minutes later, the inverter indicator “UPS ON” will light up
and the “BYPASS” indicator will go out. At this point, the UPS unit has
entered into normal operation.
In case the bar-type indicator indicates a load exceeding 100%, the
buzzer will beep every half second, alerting the user that excessive load
has been connected to the system. You may disconnect loads of
secondary devices such as printers. If the “Power Mains” indicator lights
up, the AC power source is correctly connected. If both the “Power Mains”
and “Battery” indicators light up at the same time, it indicates that the
voltage or frequency of theAC source has exceeded its range.
(2) UPS I/P breaker off: Checks and confirms that the standby function of the
battery is normal.
The UPS unit will beep every 4 seconds. The Power Mains indicator goes
out.
(3) Press the “OFF” button (**Note**)
Pressing the “OFF” button once will switch the load devices over to the
bypass circuit for standby power supply. Pressing the “OFF” button a
second time within 4 seconds will disengage the output socket(s)
and the connected load device(s) from power. Please turn off all the
connected loads according to all necessary procedures before pressing
the “OFF” button twice.
(4) The UPS unit has “DC (battery) start up” and “alarm mute” functions.
When the Power Mains fails, the load indicator will function as a “Battery
Capacity Indicator” during standby. Direct start up in Battery Mode: When
there is no Power Mains input, press the “ON/Mute” button to start the
UPS unit for a Battery Mode start up. The first-time use of “DC (battery)
start up” is only available when the unit has been started with the Power
Mains.
Alarm Mute: Pressing the “ON/Mute” button will stop the alarm. Pressing
the button again will re-activate the alarm. Please note every button needs
to be pressed for more than 1 second for activation.
2.5 Battery Maintenance
1. When the UPS unit is not in use, the battery shall be re-charged every
three months for at least 12 hours. In warm areas, charge the battery
every two months for at least 12 hours.
2. Batteries tend to age when in operation. In general, batteries have a
lifespan of 3-5 years.An aged battery must be replaced, or the battery
may leak battery fluid and create a fire hazard.

5. Communication Interface Port
The RACK-installed UPS has a standard DB-9 female serial port. This port provides
several signals and their respective functions are given as follows:
Pin Function
1 Low battery power (transistor collector open, see the figure below).
2 UPS TxD (normal RS-232 transmission)
3 UPS RxD (normal RS-232 transmission)
4 Switched off by remote control (max. 5-12 VDC,10-24mA) during
the battery operation mode.
5 Common ground for pins 2, 3, and 4
6 Switched off by remote control (pin 5 shorted) during any operation
mode.
7 Low battery power (transistor collector open; see the figure below).
8 Abnormal Power Mains input (transistor emitter open; see the
figure below).
9 Abnormal Power Mains input (transistor collector open; see the
figure below).
Pin Assignment Collector to Emitter
Note: Maximum allowable voltage and current fed into pins 1, 7, 7 and 9 are
60VDC/10.0mA. If these values are exceeded, internal optical couples of
the UPS may get burnt.
Pin 4 – Explanations of remote control switch off of battery operation
1. This pin is only functional when the UPS is in battery mode. Pin 4 will ignore
any signal when the UPS is in the normal mode where the Power Mains is in
normal supply.
2. Pin 4 requires a 5-12 VDC signal to switch off the unit. A 5-12 VDC signal
sustained for more than 1.5s is required for switch off of the unit; any signal
shorter than 1.5s will be ignored. When Pin 4 receives a switch off signal
Open
collector
Open
emitter

14 15
longer than 1.5s, this signal can no longer be canceled.
3. The UPS is not switched off immediately after the receipt of a switch off signal
at Pin 4; instead, the unit starts a 2-minute timer and the switch off will only
take place after 2 minutes.
Note: the switch off timer cannot be stopped midway once it is activated.
4. In case the Power Mains resumes supply during the 2-minute countdown, the
timer still fulfills the countdown and switches off the UPS. The UPS will remain
OFF for at least 10s before automatically resuming the LINE MODE, even if
the AC input is resumed before the UPS is switched off.

Bypass Protection Limits
Disable Bypass operation If input voltage exceeds ±15% of the nominal voltage
Re-enable Bypass
operation If input voltage returns to within ±10% of nominal output voltage
Note - The intent of low and high line transfer and comeback voltages is to
establish about 7 VAC of hysteresis. The ±3.1 VAC tolerance is to mean that if the
transfer point is +2 VAC, then the retransfer point should also be about +2 VAC. If
the low line transfer point is +3.1 VAC and the retransfer point is –3.1VAC, the
hysteresis could be reduced to 0.8 VAC. To prevent this, the voltage error should
be in the same direction and about the same magnitude for each transfer point
voltage pair.
Note – At a nominal line voltage of 127 VAC, the maximum AC input will be
reached before 127 + 15% and the unit will go to battery mode before the bypass
reaches the disable voltage, so 127 +15% can be ignored.
Note - If the transfer points are specified using L-N voltages, the L-L voltage will
depend upon whether the inverters are 120 or 180 degrees apart. For reference,
this table shows the equivalent L-L voltages for the specified L-N voltages.
