Maintenance, service and faults
• The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified
maintenance personnel.
• Caution -risk of electric shock. Even after the unit is disconnected from the mains (building wiring
outlet), components inside the UPS system are still connected to the battery and electrically live
and dangerous.
• Before carrying out any kind of service or maintenance, disconnect the batteries and verify that
no current is present and no hazardous voltage exists in the terminals of high capability
capacitor such as BUS-capacitors.
• Only people that are adequately familiar with batteries and with the required precautionary mea
-
sures may replace batteries and supervise operations. Unauthorized personnel must be kept
well away from the batteries.
• Caution -risk of electric shock. The battery circuit is not isolated from the input voltage.
• Hazardous voltages may occur between the battery terminals and the ground. Before touching,
please verify that no voltage is present!
• Batteries may cause electric shock and have a high short-circuit current. Please take the precaution
-
ary measures specified below and any other measures necessary when working with
batteries:
a)
Remove wristwatches, rings and other metal objects
b)
Use only tools with insulated grips and handles.
c)
Wear rubber gloves and boots.
d)
Do not lay tools or metal parts on top of batteries.
e)
Disconnect charging source and load prior to installing or maintaining the battery.
• When changing batteries, install the same number and same type of batteries.
• Do not attempt to dispose of batteries by burning them. This could cause battery explosion.
• Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It
may be toxic.
• Please replace the fuse only with the same type and amperage in order to avoid fire hazards.
• Do not dismantle the UPS system.

Setup the UPS
Step 1: UPS input connectio
n
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords. The
power cord is attached to the UPS. The input plug is a NEMA 5-15P.
Step 2: UPS output connection
There are two kinds of output receptacles: programmable outlets and general outlet. Please connect
non-critical devices to the programmable outlets and critical devices to the general outlets. During
power failure, you may extend the backup time to critical devices by setting shorter backup time for
non-critical devices.
