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.
1.4 Transport
★
Please transport the UPS only in the original packaging (to protect against shock
and impact).
1.5 Storage
★
The UPS must be stockpiled in the room where it is ventilated and dry.
