1.3 Maintenance, servicing and faults
★
The UPS operates with hazardous voltages. Repairs may be carried out
only by NEXT UPS Systems 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:
－
