Uninterruptible Power Supply
• Connect your UPS power module’s grounding terminal to a grounding electrode conductor.
• The UPS is connected to a DC energy source (battery). The output terminals may be live when the UPS
is not connected to an AC supply.
• Warning labels should be placed on all primary power switches installed in places away from the
device to alert the electrical maintenance personnel of the presence of a UPS in the circuit. The label will
bear the following or an equivalent text:
Before working on this circuit
Isolate Uninterruptible Power Supply (UPS)
Then check for Hazardous Voltage between
all terminals including the protected ground
Risk of Voltage Backfeed
1.5 Maintenance
• Even after the UPS is disconnected from the mains, the components inside are still connected to the
battery packs which may be potentially 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.
• Verify that no between the battery terminals and the ground is present before maintenance or repair.
In this product, the battery circuit is not isolated from the input voltage. Hazardous voltages may occur
between the battery terminals and the ground.
• Batteries may cause electric shock and have a high short-circuit current. Please remove all wristwatch
-
es, rings and other metal personal objects before maintenance or repair, and only use tools with insu
-
lated grips and handles for maintaining or repairing.
• When replacing the 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. The batter
-
ies must be rightly deposed according to local regulation.
• 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 disassemble the UPS system.

• When replacing batteries, it is necessary to replace ALL batteries with the same quantity, type & capac
-
ity.
• Do not plug or unplug the battery connector if UPS is working in battery mode.
• This unit is not designed for outdoor use.
1.6 Operation
• Do not disconnect the ground conductor cable on the UPS or the building wiring terminals in any time
since this would cancel the protective ground of the UPS system and of all connected loads.
• The UPS system features its own, internal current source (batteries). The UPS output receptacles or
output terminal blocks may be electrically live even if the UPS system is not connected to the building
wiring system.
• In order to fully disconnect the UPS system, first press the “OFF” button and then disconnect the
mains.
• Ensure that no liquid or other foreign objects can enter into the UPS system.
• The UPS can be operated by any individuals with no previous experience.
