External Optional Cabinets

EXT-MaintX3-1&2on UPS Parallel Board M3 (leave open if no external bypass switch is used). Pro- vides external maintenance bypass interlock protection for the UPS. Short circuit means external bypass closed.

EXT-Out(X3-3&4)on UPS Parallel Board (leave shorted if no external output switch is used). Pro- vides external output interlock protection for paralleled UPS modules. Short circuit means external output switch closed.

4.3Isolation Transformer Option

Isolation transformers are required in cases requiring galvanic isolation between the input supply mains and the UPS.

These options are housed in cabinets and they are available for every range of UPS. These optional cabinets provide the Top Cable entry function.

NOTE

Terminals and cabling for the battery connection is not a part of the MBP or TC cabinet.
