, the four set screws holding the two
mounting bracket shoes to the center section of the enclosure until
the shoes are free to pivot. Remove circuit breaker mounting bracket
assembly.
5. Remove operating rod assembly by pressing assembly towards
receptacle and rotating clockwise until it is free from operating arm
shaft.
6. Align square hole with interlock shaft and then remove operating rod
assembly.
7. Remove the aligning and locking plate fastened to flat surface on

ENCLOSURE ASSEMBLY
1. Replace receptacle assembly. Be sure that receptacle is rethreaded
into enclosure to the original depth noted pre viously.
2. Place aligning and locking plate over 1/4 inch pin on center section
of enclosure and fasten plate to receptacle assembly using the two
slotted hex head screws.

operating rod assembly.
4. Replace the circuit breaker mounting frame, circuit breaker and
operating rod guide.
5. Test the interlock mechanism, complete all wiring connec tions and
replace upper cover.
INTERLOCK TEST
With the Arktite plug removed from the receptacle it should be impossible
to move operating handle to “on” position.
Insert plug into receptacle. This should actuate the interlocking mechanism
and allow the operating handle to be moved to ON position. The plug at this
time should resist all normal efforts to withdraw it from the receptacle even
while pressing the release lever.
Move operating handle to OFF position, press release lever and withdraw
the plug. It should again be impossible to move the operating handle to the
ON position.
ELECTRICAL TESTING
Do not connect to power until the following electrical tests have been
performed:
• Make continuity check of wiring to verify correct phasing and
grounding connections.
• Check insulation resistance to be sure system does not have any
short circuits or unwanted grounds.
MAINTENANCE
Electrical and mechanical inspection of all components must be performed
on a regular schedule determined by the environ ments and frequency of
use. It is recommended that inspection be performed a minimum of once a
year.
1. Inspect all wire terminals for tightness. Discoloration due to excessive
heat is an indicator of a possible problem and should be thoroughly
investigated and repaired as necessary.
2. Check grounding and bonding for correct installation and secure
connection.
3. Clean exterior surfaces making sure nameplates remain legible.
4. Inspect housings and replace those which are broken.
5. Check receptacle contacts for signs of excessive arcing or burning and
replace if necessary.
In addition to these required maintenance procedures, we recommend an
Electrical Preventive Maintenance program as described in the National Fire
Protection Association Bulletin NFPA No. 708.
WARNING
Electrical power must be turned
off
before and during disassembly or
maintenance.
