7. CLEAN COVER AND HOUSING:
Before closing the cover ➂, it is strongly recommended that
all dirt, debris and other foreign materials be removed from
the interior.
•This action should be taken to help eliminate the possibility
of unwanted shorts or grounds.
•Make sure the cover gasket surface is clean and free of any
tears or damage.
•Clean the mating surface of the housing ➃in the same
manner as the enclosure cover ➂.
8. CLOSE ENCLOSURE COVER:
A. Close the cover ➂.
B. Engage latches ➁.
9. POWER:
With all electrical tests successfully completed, the door
latched closed and the receptacle turned "OFF", power may
be applied to the WSRD unit.
10. OPERATION:
A. The WSRD interlocked receptacle can now be turned to
the "ON" position by lifting the operating handle ➉to the
upper-most position.
•SAFETY FEATURE - The receptacle is interlocked to the
operating handle mechanism so that a mating plug cannot be
removed when the switch is in the "ON" position.
B. A hole is provided in the housing lock-out ➈and operat-
ing handle ➉for the use of a padlock ( See "FIGURE C" ) to
prevent unauthorized movement of the operating handle ➉
from the "OFF" position.
11. MAINTENANCE:
A. INSPECTION: Complete unit must be inspected regularly.
Schedule of inspections is determined by frequency of use
and environmental conditions.
• It is recommended that inspections be carried out at
least once a year.
DURING THE INSPECTIONS, PERFORM AT LEAST
THE FOLLOWING:
1. Electrical power supplying the WSRD interlocked receptacle
must be turned "OFF" before performing maintenance.
2. Inspect all conductor terminations for secureness.
• Confirm torque values given in "TABLE C" and "TABLE E".
• Discoloration due to excessive heat is an indication of
possible problems and should be thoroughly
investigated and repaired as necessary.
3. Check grounding and bonding effectiveness/continuity.
• Retorque connections to original values.
04. Check gaskets for damage. Replace as necessary.
05. Check all hubs for tightness and retorque as neces-
sary.
06. Clean interior of all foreign materials.
07. Make sure all openings are closed.
08. Make sure that receptacle assembly flip-cover 11 seals
againts the receptacle housing.
09. Make sure the receptacle assembly nameplate located
on the outside of the cover remains clean and legible.
• Do not paint nameplate
.
10. Make sure the assembly labels located on the inside of
the cover remain clean and legible.
B. DISCONNECT SWITCH:
Disconnect switches occasionallt fail with use and need to
be replaced.
The disconnect switch used in this receptacle must only be
replaced with the same type and brand as factory installed.
Doing so will not affect the UL Listing.
To replace disconnect switch -
• Referring to "FIGURE C", loosen the line and load side lug
screws hof the disconnect switch and remove wires from
the switch. Take note of the orination of these wires for proper
reassembly. Also note that the wires ithat connect the
recptacle to either the disconnect switcch directly (non-fused
version), or connect the receptacle to the fuse base (fused
version) are numbered according to the phase location (See
"FIGURE B").
• Remove disconnect switch and fuse base (if applicable)
mounting screws mountin screws 14. Remove disconnect
switch 12 and fuse base 13 (if applicable).
• Replace disconnect switch and fuse base, if applicable, with
the appropriate switch kit as shown in "TABLE E", reversing
the steps taken to remove them. Make sure to reconnect the
wires to the same locations as before disassembly. Replace
fuses, if necessary, for fused receptacle.
used in this interlocked receptacle is not replaceable. In case
of disconnect switch failure, entire unit must be replaced.
WARNING
• If any part(s) of the "WSRD" unit or the mating plug
appear to be missing, broken or show signs of damage:
DISCONTINUE USE IMMEDIATELY!
This condition could cause serious or fatal personal injury
due to electrocution and/or equipment damage. Repair with
the proper replacement part(s) before continuing service.
•It is recommended that an electrical preventive main-
tenance program, such as found in the National Fire
Protection Bulletin NFPA 70B, be followed in addition to
the above.
Note that the WSRD interlocked receptacle cannot be
turned "ON" without a mating plug engaged.
