1.2 Operation
★
Do not disconnect the mains cable on the UPS or the building
wiring socket (grounded shockproof socket) during operation as
this would remove the ground to the UPS and of all connected
loads.
★
The UPS features its own, internal current source (batteries).
You may be electric shock when you touch the UPS output
sockets or output terminal block even if the UPS is not
connected to the building wiring socket.
★
In order to fully disconnect the UPS, first press the Standby
button, then disconnect the mains lead.
★
Ensure that no liquid or other foreign objects can enter the UPS.
★
The UPS can be operated by any individuals with no previous
experience.
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!
