★ For safety consideration, do not disconnect the mains cable on the UPS or the building wiring socket
(grounded shockproof socket) during operation, the grounding for the UPS and all loads connected will
be disconnected.
★ The 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, first press the OFF button to turn off 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. This system is to be serviced by qualified service person only. There
are NO USER SERVICEABLE PARTS inside the UPS.
★ Remove the protective panel only after disconnecting the terminal
connections.
1.3 Maintenance, servicing, and faults
★ The UPS operates with hazardous voltages. Repairs may be carried out only by qualified
maintenance/service person.
★ 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 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. 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!
★ 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. The following precautions should be
observed when working on batteries:
a) Remove watches, rings or other metal objects
b) Use tools with insulated handles
