1.2 Operation
•For safety consideration, do not disconnect the mains cable on the UPS or the buil-
ding wiring socket (grounded shockproof socket) during operation, the grounding
for the UPS and all loads connected will be disconnected.
•
e UPS features its own, internal current source (batteries). You may be electric
shocked 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, rst press the OFF button to turn o the UPS,
and then disconnect the mains lead.
•Ensure that no liquid or other external objects can enter the UPS.
•Do not remove the enclosure.
person only.
ere are NO USER SERVICEABLE PARTS inside the UPS.
•Remove the protective panel only a er disconnecting the terminal connections.
1.3 Maintenance, servicing and faults
•
e UPS operates with hazardous voltages. Repairs may be carried out only by
quali ed maintenance/service person.
•Caution - risk of electric shock. Even a er 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 quali ed person.
•Caution - Risk of Energy hazard, 24/36/48/72V, 7/9AH battery. Before replacing
batteries, remove conductive jewelry such as chains, wrist watches, and rings, High
energy through conductive material could cause severe burns
•Caution - risk of electric shock.
voltage. Hazardous voltages may occur between the battery terminals and the
ground. Verify that no voltage is present
•before servicing!
• CAUTION: A battery can present a risk of electrical shock and high short-circuit
current. Contact with any part of a grounded battery can result in electrical shock.
e following precautions should be observed when working on batteries:
a) Remove watches, rings or other metal objects
b) Use tools with insulated handles
c) Wear rubber gloves and boots.
d) Do not lay tools or metal parts on top of batteries.
