3.4 Requirements of wiring cables and protect device for EDX series
UPS
External batteries of EDX Series UPS require serial connection of positive and
negative for each group of 14-16 batteries (12VDC per battery) with the same
capacity, nominal voltage for each group being 168VDC-192VDC. Battery
capacity and number of groups can be selected at your option. Battery pack
must be equipped with disconnection and over-current protection facilities,
and overload and line voltage should also be taken into consideration for wire
diameter selection. Please refer to the table below for details:

Remark:
1. Prior to connecting the power distribution system to the UPS, make sure a
correctly rated three-pole circuit breaker is installed.
2. When single-phase current exceeds 100A, switches of protective atmosphere
should be equipped with arc control devices,It should be D-curve air switch with
UL certi
fi cation according to the customer requirement ;
3. Battery positive/negative/N wire si z e: indicates UPS and battery bank wire si z e ;
red wire signi fi es the positive polarity and black wire the negative, while blue wire
the neutral.
4. All battery cables should be of equal length (positive, negative and N) with total
length of no more than 40m.
