Step 4. This UPS is equipped with an auto-charge feature. When the
UPS is plugged into an AC outlet, the battery will automatically charge,
even when the unit is switched off.
Step 5. To maintain an optimal battery charge, leave the UPS plugged
into an AC outlet at all times.
Step 6. Before storing the UPS for an extended period of time, turn
the unit OFF. Then cover it and store it with the batteries fully charged.
Recharge the batteries every three months to ensure good battery
capacity and long battery life. Maintaining a good battery charge will help
prevent possible damage to the unit from battery leakage.
Step 7. The UPS has one USB port and one Serial port that allows
connection and communication between the UPS and any attached
computer running the Power Master software. The UPS can control the
computer's shutdown during a power outage through the connection
while the computer can monitor the UPS and alter various programmable
parameters.
NOTE:
Only one communication port can be used at a time. The port not
in use will automatically become disabled or the serial port will be disabled if
both ports are attached.
Step 8. EPO (Emergency Power Off) / ROO (Remote On/Off) Port:
EPO/ROO ports allow administrators the capability to connect the UPS
unit to customer-supplied EPO/ROO switches. If EPO is enabled, these
installations give operators a single access point to immediately power-
off all equipment connected to the UPS during an emergency. If ROO is
enabled, these installations give operators a access point to turn on/off
UPS remotely.
Step 9. To avoid electric shock, turn the unit OFF and disconnect the
unit from utility power before hardwiring the UPS (IN/OUT power cord).
The IN/OUT power cord MUST be grounded.
