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 capacitors such as BUS-capacitors.
To avoid electrical shock, turn off the unit and unplug it from the AC power source before
servicing the battery.
Only persons that 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, verify that no voltage is present!
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.
When replacing batteries, replace with the same type and number of batteries or battery
packs.
