INSTALLATION
We strongly recommend that only a licensed electrician install this product.
This Explosion Proof Control Station comes preconfigured from factory with two pilot lights colored Red.
WARNING: Mis-wiring could cause permanent damage.
DO NOT connect with power applied.
1. Choose a suitable location to mount the control station where conduit can reach the box. 3/8”-16 or 3/8”-24 bolts
are recommended for mounting the box with a minimum bolt length of ¼” depending on the location.
2. Run control wire to box following appropriate methods via conduit.
3. Wire according to the wire diagram visible on each device.
After wiring each system, secure the enclosure and enable the circuit to test each system.
NOTE: All installations must comply with applicable local and/or National Electrical Code
CAUTION: Disconnect this device from the supplying circuit before entering. Keep assembly tight while circuits are alive.
Pilot Light:
120 V AC, 250 V AC, 12 V AC/DC, or 24 V AC/DC

OPERATION
Operate this pilot light only at its rated voltage. These devices are individually pre-sealed. Therefore, the enclosure in
which they are installed does not be require external seals. However, the enclosure must be marked with a cautionary
statement such as “Caution: Disconnect this device from the supplying circuit before entering. Keep assembly tight while
circuits arealive”. This statement must be permanently visible after the enclosure has been installed.
MAINTENANCE
The Pilot Light require no special maintenance, other than a periodic inspection for damage or a burned-out lamp. To
replace the lamp, unscrew the lens/guard assembly. Replace the lamp only with one of exactly the same type and rating.
The lens assembly threads should be lubricated occasionally to prevent from binding.
Damaged or worn parts should be replaced immediately to ensure the safety of the system. Refer to the Parts Drawing
below. Consult Larson Electronics for specific partnumbers.

1.. DIRECTIONS FOR BOX INSTALLATION
1. Mount the back box by means of mounting lugs, install conduit nipple and sealing fittings one each to be
installed on each conduit entrance or exit to the enclosure back box in Class l and Class ll areas (Reference:
Article 500 NEC) thread conduit into sealing fitting (Note: for Class l areas the conduit should engage [5]
full threads).
2. The conduit thread should be lubricated with a non-electrical insulating lubricant or pipe joint compound that
will not promote corrosion or chemically attack aluminium.
3. After conduit system has been properly installed, pull the wires and make electrical connections as required.
The electrical circuits and ground continuity should be checked with an instrument approved for the area.
(Notice: connect only copper wire to this device).
4. All conduits entering or leaving the enclosure must be sealed within 18” of the enclosure with listed sealing
fittings.
5. Caution must be taken during installation to be sure that the ground flange flame joints of the cover and the
box are not scratched, nicked or damaged.
6. Before assembly of the cover to the box, the mating ground surfaces of both the box and cover should be
wiped clean to assure that the ground flame joint will be free of all foreign particles such as lint, dust or dirt.
7. After tightly bolting the cover assembly/assemblies to the enclosure all box to cover, flame joints should be
checked with a 0.0015” thick feeler gauge such that the gauge will not enter the flame path more than 1/8” at
any point.
2.. MAINTENANCE
All moving shafts should be lubricated occasionally to prevent binding. Only use a lubricant which is
suitable for use with aluminium or stainless steel such as general purpose or high temperature lubricants. If
devices are to be installed in corrosive areas which will attack aluminium alloys containing less than 0.4%
copper (boxes and covers) and 303 stainless steel (mostly shafts), the device should be suitably protected
from the corrosive material.
3.. CAUTION
To prevent ignition of hazardous atmospheres, disconnect from the supply circuits before opening the
enclosure; keep tightly closed while circuits are energized.
