1.3 Maintenance, servicing and faults
★ The UPS 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 power supply (building wiring socket), components inside the
UPS are still connected to the battery which are potentially dangerous.
★ Before carrying out any kind of service and/or maintenance, disconnect
the batteries. Verify that no current is present and no hazardous voltage
exists in the capacitor or BUS capacitor terminals.
★ Batteries must be replaced only by qualified personnel.
★ 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. Verify that no voltage is present before
servicing!
★ Batteries have a high short-circuit current and pose a risk of shock. Take
all precautionary measures specified below and any other measures
necessary when working with batteries:
－ remove all jewellery, wristwatches, rings and other metal objects
－ use only tools with insulated grips and handles.
★ When changing batteries, replace with the same quantity and the same
type of batteries.
★ Do not attempt to dispose of batteries by burning them. It could cause
explosion.
★ Do not open or destroy batteries. Effluent electrolyte can cause injury to
the skin and eyes. It may be toxic.
★ Please replace the fuse only by a fuse of the same type and of the same
amperage in order to avoid fire hazards.
★ Do not dismantle the UPS, except the qualified maintenance personnel.
