4-2-5 Wiring Notices
Battery
(1) For safety, professional engineers should put on isolated gloves, use tools with isolated handles. It is
recommended that two or more engineers are working on wiring the batteries.
(2) Check if batteries are well grounded and make sure your limbs are dry before you perform battery
disconnection.
(3) Disconnect UPS and batteries (switch off the battery breaker and unplug the battery connector) and
then disconnect cables of batteries on every layer.
(4) During battery disconnection, do not touch neighboring batteries while processing cables or plates of
batteries in order not to cause short circuit.
(5) During battery connection, finish connecting batteries on each layer firstly and then interconnect the
battery layers. Finally connect the battery connector to the battery breaker.
(6) Check terminal voltage and polarity of the batteries and the UPS battery input.
Check the following items after wiring setup:
(1) Every terminal is correctly connected.
(2) PE cable is correctly grounded.
(3) Every screw is tightly screwed.
(4) All switches should stay off (at off position).
(5) Output power distribution panel is not short circuited.
(6) Battery terminals and polarities are correctly connected.
