Ensure that no liquid or other foreign objects can enter the
UPS.
1.3 Maintenance, servicing and faults
★
The UPS operates with hazardous voltages. Repairs should 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
terminal), components inside the UPS are still connected to the
battery which are potentially dangerous.
★
Before carrying out any kind of service and/or maintenance,
please 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.
