maintenance personnel.
★
Earth connection essential before connecting to the building wiring terminal.
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 output socket or output terminal block may be electrically lived even if the
UPS system is not connected to the building wiring terminal.
★
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!
★
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.
