Data For Input/Output And Battery Over Current Protection And Wire Sizing - GE FGC TLE Series Manual

4.7.3 Data for Input/output and battery over current protection and wire sizing

NOTE !
•
Please read the safety precautions at the front of this guide carefully, and
thoroughly review the battery manufacturers installation and maintenance
manual before connecting the batteries to the UPS.
•
Remote battery cabinet is external and not provided with UPS.
• For Battery and AC input and output circuits the disconnect device is not
provided inside the UPS. It shall be part of the building installation.
• Protect Battery and AC input and output circuits with an appropriate UL489
Branch Circuit Protection (DC fuse or circuit breaker), using the current data in
the chart below.
• Minimum battery cable requirement is based on the current data below.
•
The maximum available fault current from the battery supply is: 20kA.
• The minimum breaker voltage rating is 540V.
These maximum and nominal ratings should be considered when choosing the appropriate AC
NEC (National Electric Code) Section 210-20 (A) rules must be applied.
DC current rating is the nominal battery discharge current which the UPS allows.
