time model (“
L
” model)
(1) Use the battery pack with voltage: 36VDC for 1KL (3 pcs of 12V
batteries), 96VDC for 2KL/ 3KL (8 pcs of 12V batteries).
Connection of batteries more than or less than required will cause
abnormality or permanent damage.
(2) One hard wiring type battery terminal on the rear panel is used for
connecting the battery pack.
(3) The battery connection procedure is very important. Any
incompliance may result in the risk of electric shock. Therefore,
the following steps must be strictly complied with.
(4) Make sure the mains input is cut off, if there is a battery breaker
then turn it off first.
(5) Remove the small cover of terminal block, prepare the battery
cable which should be able to carry the current of >30A for 1KVA,
>22A for 2KVA, >33A for 3KVA, the cross section area should be
great than 4
mm
