9. AUX DC OUTPUT: Output terminal provides DC power source to the relay card (Optional
Dry contact relay box).
10. RS232 communication port: DB-9 connector
11. TEL Surge Protection: Data line surge protection for telephones

2. Installation

2.1 Inspection: Upon receiving the UPS, inspect it. The packaging is recyclable. Save it for
reuse or dispose properly.
2.2 Placement: To prevent the risk of fire or electronic shock, install the UPS in a
temperature and humidity controlled ventilated enclosure, free of conductive contaminants,
moisture, flammable, gases, and corrosive substances.
To reduce the risk of electronic shock, do not remove cover, it has no user-serviceable parts
Hazardous live parts inside this unit are energized from the battery supply even when the
input AC power is disconnected
2.3 Utility power: The terminal block is used to "hardwire" the UPS, thus allowing
connection of input/output wiring. Use AWG wire as stated in the table. Input / Output wires
should be secured with terminal block screws using 9 lb.-in. of torque. The input utility power
should match with the UPS. (For example, the voltage rating of UPS is 120V/(220V), input
utility should also be 120/(220)).
2.4 Connection:
a. Connect the AC Input power conductors (L, N, and G) to the UPS Input Terminal
Blocks (L, N, and G) respectively.
b. Connect the Output Power Conductors (L, N, and G) from the UPS Output Terminal
Blocks to the load equipment (L, N, and G) respectively.
c. The UPS Input and Output Terminal Blocks can accept conductor sizes ranging from
10AWG to 18AWG.
