Arcflash Reduction Maintenance Switch
5. Completion of the Arcflash Reduction
Maintenance Switch Installation
Step 1: Installing the Arcflash Reduction Maintenance
Switch Mode Selector Switch, Indicator Light, and
Battery Holder
Figure 12. Overview: Typical Installation of the Arcflash Reduction
Maintenance Switch Mode Selector Switch, Indicator Light, and
Battery Holder.
Each installation of the Arcflash Reduction Maintenance Switch
mode selector switch, indicator light, and battery holder may vary
due to the type of breaker, type of cell, or components / options
mounted in or on the cell, etc. Because of these factors, the pro-
cedures in this section are general in nature. However, there are
some basic guidelines that should be considered and followed dur-
ing installation of the Arcflash Reduction Maintenance Switch
mode selector switch, indicator light, and battery holder.
In most cases, mounting the mode selector switch, indicator light,
and battery holder to the cell door, opposite to the cell door
hinges, is the best alternative.
In certain DS applications, it may not be possible to mount the
mode selector switch, battery holder, and indicator light on the
cell door due to interference problems when the breaker is racked
out in the "test" position and the cell door closed. In this case, it is
necessary to mount the components to the "accessory panel" or
drawer above the enclosure. See Figure 13.

Applications.
