1-5. 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 and/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 persons are adequately familiar with batteries and with the required
precautionary measures may replace batteries and supervise operations.
Unauthorized persons 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!

Caution - Do not dispose of batteries in a fire. The batteries may explode.

Caution - Do not open or mutilate batteries. Released electrolyte is harmful to the
skin and eyes. It may be toxic.

Batteries may cause electric shock and have a high short-circuit current. Please take
the precautionary measures specified below and any other measures necessary when
working with batteries:
a) Remove watches, rings, or other metal objects.
b) Use tools with insulated 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.
f) Remove battery grounds during installation and maintenance to reduce
likelihood of shock. Remove the connection from ground if any part of the
battery is determined to be grounded.

When changing batteries, install the same number and same type of batteries or
battery packs.

For UPS with internally mounted battery
a) Instructions shall carry sufficient information to enable the replacement of the
battery with a suitable manufacturer and catalogue number.
b) Safety instructions to allow access by Service Personnel shall be stated in the
installation/service handbook.
c) If batteries are to be installed by Service Personnel, instructions for
interconnections, including terminal torque, shall be provided.

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.
