Arcflash Reduction Maintenance Switch

Application and Installation

Note: 

The indicator light is pre-wired to the mode selector switch. There-

fore, the hole for the indicator light must be close enough to the mode 

selector switch to accommodate the wiring.

C. Determine the best location for the battery holder.  Note that 

the harness connecting the mode selector switch to the bat-

tery holder is short so the battery holder must be installed in 

close proximity to the mode selector switch. 

Mark the center of the mounting area, then drill a 0.406” 

(22.5mm) hole through the mounting surface.  Using a 

0.500” Greenlee Slug Buster Knock-out Punch, cut the inter-

mediate hole for the battery holder.  Then use the 1.50” (49.6 

mm) knock-out punch to cut the full mounting hole.  Be sure 

to remove all metal shavings that have dropped into the 

breaker or cell.

Figure 16. Mode Selector Switch, Indicator Light, and Battery 

Holder Holes Cut in the Mounting Surface.

D. Using the battery holder as a template, mark then drill four (4) 

0.109” holes in the mounting surface to accept the battery 

holder mounting screws.

Figure 17.  Marking the Battery Holder Mounting Holes.

E. Remove the backing from the self-adhesive mode selector 

switch label, center the label above the mode selector switch 

hole, then apply the label to the mounting surface as shown.

Surface.

F. Carefully remove the lock nut from the mode selector switch 

assembly. Leave the rubber grommet on the mode selector 

switch assembly.

Assembly.

G. Insert the mode selector switch assembly through the hole in 

the mounting surface. Install the lock nut (removed in Step F) 

on the mode selector switch assembly, then tighten the lock 

nut to secure the mode selector switch assembly to the 

mounting surface.

H. Loosen the clamping screw on the LOTO device. Place LOTO 

device onto mode selector switch housing, with the LOTO 

hinge towards the top, until it is flush with the mode selector 

switch’s metal enclosure. Tighten the clamping screw 

securely. Ensure the LOTO cover closes over switch freely.
