4. UPS placement location :
As the UPS is equipped with fan forced cooling, please place the UPS in a
well-ventilated area. Maintain minimum clearance of 100mm at the front of the UPS and
300mm at the rear and around both sides of the UPS for efficient heat dissipation and
easy-maintenance.
Step 1: UPS input connection
When connecting the UPS to the mains supply always use a three-pin plug, three-wire,
grounded receptacle and avoid using extension cords.
Step 2: UPS output connection
There are two kinds of socket-type outputs: programmable outlets (white coloured outlets)
and general outlets (black coloured outlets). Connect non-critical devices to the programmable
outlets and critical devices to the general outlets. The backup time to critical devices may be
extended during power failure by setting shorter backup time for non-critical devices.
Step 3: Communication connection
Communication port:
USB port RS-232 port Intelligent slot
To allow for unattended UPS shutdown/start-up and status monitoring, connect the
communication cable on one end to the USB or RS-232 port of the UPS and the other to the
USB or RS232 communication port of your PC. With the monitoring software installed, you can
schedule UPS shutdown/start-up and monitor UPS status through the PC.
The UPS is equipped with an intelligent slot to accommodate either an SNMP or AS400 card.
When installed, either the SNMP or AS400 card will provide advanced communication and
monitoring options for the UPS.
Please Note: The USB port and RS-232 port can NOT operate at the same time.
Step 4: Disable and enable EPO function
This UPS is equipped with EPO function. By default, the UPS is delivered from factory with Pin
1 and pin 2 closed (a metal plate is connected to Pin 1 and Pin2) for UPS normal operation. To
activate Emergency Power OFF (EPO) function, remove the two screws on the EPO port to
remove the metal plate.
Illustration is in the closed switch
position for normal UPS operation.
