It is recommended to discharge the cells before storage and/or transportation the UPS. The
recommended way of discharging these cells is to remove all connections to the UPS and then set the
UPS power switch to the “ON” position.
NOTE
: UPS LEDs will turn on and output voltage will be present
on the UPS output (OUT) terminals until the cells discharge below the working voltage. Leave the UPS in
a safe, controlled environment until the LEDs power off. It will take approximately one hour with no
load for the cells to drain below the working voltage. Once the LEDs turn off, it is now safe to place the
UPS into the appropriate packaging for storage or transport.
NOTE
: Store and/or transport the UPS
with the power switch in the “ON” position.
Note that when the toggle switch is in the “ON” position, voltage may still be present at the DC output
terminals even when the input terminals are disconnected from power. Do not attempt to make
connections to the terminals when the toggle switch is in the “ON” position.
Warning:
A disconnect switch shall be provided by others for DC input circuit and shall be in accordance
with the National Electric Code, ANSI/NFPA 70.
Connect the conductors according to the wiring diagram on Figure 7: System Wiring Diagram. Consult
the Load Sense Module Instruction Manual before installing the Load Sense Module. Omit connections
to the optional Load Sense Module if redundant power connection is not used.

DC POWER INPUT
The two screw terminals above the legend marked “INP” are to be connected to an external DC power supply.
The terminal marked “+” is to be connected to the positive supply line from the power supply and the terminal
marked “-” is to be connected to the return or ground line
4
to the power supply. The input maximum voltage
should not be greater than 28 VDC.
The terminals are designed to accept 18 to 12 AWG (0.823 mm
2
to 3.31 mm
2
) wire. Torque terminal screws to
7 in-lbs. (0.7909 Nm). Ensure the proper local and national regulations are followed when selecting wiring
components with regards to the system configuration.
4.7.
SENSE INPUT
The two terminals above the legend marked “SEN” are to be connected to the optional load sense module,
Panduit part number UPS0030LSM. The input voltage should not be greater than 28 VDC.
The terminals are designed to accept 18 to 12 AWG (0.823 mm
2
to 3.31 mm
2
) wire. Torque terminal screws to
7 in-lbs. (0.7909 Nm). Ensure the proper local and national regulations are followed when selecting wiring
components with regards to the system configuration.
4.8.
DC POWER OUTLET
The two terminals above the legend marked “OUT” are to be connected to the load. The terminal marked “+”
is to be connected to the positive supply line to the load and the terminal marked “-” is to be connected to the
return or ground line
5
from the load. Note that the “-” terminal for the power input and power output are
connected internal to the UPS. The current draw from the UPS to the load should not be greater than 4.5 A.
The operating output voltage should not be greater than 28 VDC.
