1. DIRECTIONS FOR INSTALLATION
CAUTION:
Before beginning installation, make
sure that the supplying circuit is turn
OFF.
Be sure the flame paths (cover to box mating
surfaces and threaded openings) do not become
damaged.
Do not install in a corrosive area which will
attack the “copper free” aluminium alloys or
stainless steel shaft unless the casting and
parts have been protected against the specific
corrosive environment.
Do not locate in areas where dust, ice, snow,
or other substance will accumulate and thereby
impair the rotary operation of the device.
XCS-0S device are for surface mounting in
hazardous atmospheres as defined by NEC
article 500. They contain an electrical device
and must be sealed from the conduit system as
required by article 501-5. Type “ENY”, “EY” or
“EYS” series (or equivalent).
Install sealing fitting as required in class l & ll
areas.
(Note
: For class l (5) and class ll(3-1/2) full
threads engagement are required).
The conduit threads should be lubricated with a
non-electrical insulating lubricant, or pipe joint
compound which will not promote corrosion or
chemically attack aluminium.
After the conduit system has been properly
installed, pull the wires and make the electrical
connections as required.
The electrical circuits and ground continuity
should be checked with an instrument approved
for the area.
Flame Path machined on cover & box such that
a 0.0015” Feeler gauge will not enter more than
1/8” when fully assembled & bolted to box. Care
must be taken that surface is not damaged.
2. OPERATION
The mechanical action of these devices is
rotary.The electrical action is dependent
upon the cam configuration and the
contact block used. (See chart). An
accessory locking device may be used
with the standard selector switch without
alternations.
3. MAINTENANCE
The Shaft should be lubricated
occasionally to prevent binding. Use
Killark “LUBG” (general purpose ) or Killark
“LUBT” (high temperature) lubricants.
