Rechargeable Hazardous Location Forklift Safety System
Flashing LED Lamp, Siren - Remote Switch
Thank you for purchasing the Larson Electronics EXP-RSP-FKWL-WLS-V1 Rechargeable Hazardous Location Forklift
Safety System. Follow the steps below for installing and maintaining the unit.
WARNING: Do not attempt installation until you are familiar with all warnings, precautions, and procedures
outlined within this instruction sheet.
BEFORE INSTALLATION CONNECT FUSE INSIDE ENCLOSURE! THIS WILL ENABLE THE
BATTERY FOR NORMAL OPERATION. SEE BELOW.
In a Non-Hazardous environment:
1. Locate the fuse shipped with your unit and place it aside.
2. Remove cover bolts securing cover. Firmly grasp the right side of cover and carefully
swing open. Avoid striking cover or devices in cover or neighboring enclosures or
structures. There are 12 bolts securing the cover. This reveals the batteries and fuse
holder.
3. Install the fuse and check for operation by pressing each of the push buttons on
the switch. Pull each push button out to power off the unit.
4. To close cover, make sure cover and body joint surfaces are clean and not
scratched*. Swing cover shut. Cover/body bolt holes must match up. Hand start
corner bolts. Fully tighten all cover bolts. If cover bolts are damaged, only replace
with bolts provided by Larson Electronics.
WARNING: CHANGE FUSES IN THE DE-ENERGIZED STATE ONLY OUTSIDE HAZARDOUS ENVIRONMENT.
*INSPECT AND CLEAN THE MACHINED FLANGE (FLAM PATH) SURFACES OF BOTH THE COVER AND BOX. SURFACES MUST BE SMOOTH,
FREE OF NICKS, SCRATCHES, DIRT OR ANY FOREIGN PARTICLE BUILD UP THAT WOULD PREVENT A PROPER SEAL. SURFACE MUST
SEAT FULLY AGAINST EACH OTHER TO PROVIDE A PROPER EXPLOSION-PROOF JOINT. CLEAN SURFACES BY WIPING WITH A CLEAN,
LINT-FREE CLOTH.
APPLY A LIGHT COAT OF LUBRICANT TO FLANGE SURFACES AND CLOSE THE COVER. INSTALL AND TIGHTEN ALL COVER BOLTS TO 30
FT. LBS. MAKE CERTAIN THAT NO COVER BOLTS ARE OMITTED. USE ONLY THOSE BOLTS SUPPLIED WITH THE ENCLOSURE. CHECK THE
BOLTED JOINT WITH A 0.0015” THICK FEELER GAUGE. THE GAUGE MUST NOT ENTER THE JOINT MORE THAN 1/8” AT ANY POINT.
WARNING: MISSING BOLTS OR AN IMPROPER JOINT CAN RESULT IN AN EXPLOSION, CREATING A
POTENTIAL FOR PHYSICAL INJURY OR PROPERTY DAMAGE.
INSTALLATION PRECAUTIONS
•Do not install fixture in any classified location where the marked operating temperature exceeds the ignition
temperature of the hazardous atmospheres.
•Consult fixture nameplate for the suitability ambient temperature shown on the nameplate.
•Verify that the supply voltage agrees with fixture rating as indicated on nameplate.
•All local and national electrical/building codes must be followed when installing this fixture. For code
interpretation, consult your local authority.
•Product must be intact.
Before installing, make sure you are compliant with area classifications, failure to do so may result in bodily
injury, death and property damage. Do not attempt installation until you are familiar with the following
procedures. All installation must comply with the applicable Electrical Code. Make sure that the circuit is de-
energized before starting installation or maintenance.

INSTALLATION
We strongly recommend that only a licensed electrician install this product.
WARNING: THIS FIXTURE IS HEAVY AND MUST BE MOUNTED TO A SURFACE THAT CAN STRUCTURALLY
SUPPORT THE LOAD. SECURE THE UNIT FIRMLY TO THE SURFACE.
It is strongly suggested to use two people to proceed with the final
mounting of the fixture to avoid any possible personnel injury or damage to
the fixture.
A custom designed clamping bracket allows for easy attachment of the
unit to the top rack of explosion proof forklifts. The component’s ability to
resist bending ensures stable performance in rough environments. After
securing the preferred position on the rack, the operator can then tighten
the beam using the two adjustable bolts. It is important to tighten both
evenly and securely to prevent shaking or uneven positioning.
Mount the remote switch with the mounting ears on the back. Secure cord
from light to remote to prevent snags and in an area where it will not come
into contact with moving parts.
PUSH BUTTON OPERATION
The mechanical action of this device is maintained
push/pull operation. Push button IN to activate the
feature you wish to operate. To turn off, pull button OUT. There are two buttons located on the switch
in order to individually control the function of the Horn and Light. The Horn and Light may be operated
individually or simultaneously up to the users discretion.
CHARGING
WARNING: CHECK THE FIXTURE LABEL TO ENSURE CORRECT INPUT VOLTAGE AND FREQUENCY!
This forklift warning system is equipped with 1 foot of 16/3 chemical and abrasion resistant SOOW cord that is fitted with
an explosion proof cord cap for easy connection to explosion proof outlets during charging. Plug options include a 5-15 15
amp straight blade plug for use with 120V explosion proof outlets, a 5-20 20 amp straight blade plug for use with 120V
explosion proof outlets, or a 6-20 20 amp straight blade plug for use with 220-240V explosion proof outlets. Check product
nameplate for unit received.
BATTERIES
Plug charging cord into the appropriate power source outputting the correct voltage. The charger includes overcharge
protection allowing this unit to be left charging overnight. The unit will automatically shut off when low voltage occurs,
prolonging battery life. De-energize and remove fixture from hazardous area before maintaining batteries.

If the enclosure must be opened for servicing, to check or replace internal devices and
apparatus, the following procedures should be followed.
WARNING: Before servicing the fixture, be certain the electrical power is OFF and
remove the unit is removed from the Hazardous Environment. This fixture contains
an “Internal Voltage Source” and remains energized when disconnected from direct
line power sources.
•Remove all cover bolts. Clean and inspect. Replace any corroded, bent or otherwise
damaged bolts with new, factory authorized bolts obtained from an authorized
distributor.
•Open enclosure. Do not use hammer, screwdriver, or any prying tool to open cover,
except as shown in Figure 4.
•Inspect cover hinges. If hinges are damaged or do not function properly, contact a factory authorized service
representative for hinge replacement and installation.
•Inspect machined flange (flame path) surfaces. Surfaces must be smooth, free of nicks, scratches, dirt or any
foreign particle build-up that would prevent a proper seal. Should surface be damaged contact factory. Never
attempt to rework surfaces by sanding, grinding, ect. Surfaces must seat fully against each other to provide proper
explosion-proof joint.
•Inspect water exclusion gasket. If gasket is damaged, do not attempt field replacement or repair.
•Contact a factory authorized representative for a replacement cover. When removing gasketed cover for
replacement, do not detach hinge body from cover.
•Remove cover and hinge body from enclosure by removing the hinge pins. (see figure
5) The damaged gasket can be removed from the cover and the cover without gasket can be
safely used in Class I & II hazardous (classified) locations, however the enclosure may not be
raintight or hosedown tight.
•Clean flange surface by wiping with a clean, lint-free cloth. Apply a light coating of
lubricant to flange surfaces and close cover. Install and tighten all cover bolts to 30 ft. lbs. Make
certain no cover bolts are omitted. Use only factory authorized bolts. Check the flame joint with
a .0015” feeler gauge. The gauge must not enter the flame joint more that 1/8” at any point.
Missing bolts or an improper flame joint can result in an explosion, creating a potential for
physical injury and property damage.
LAMP REPLACEMENT
•Turn OFF the supplying circuit before opening fixture for re-lamping. To re-lamp loosen the locking screw and
remove the globe support assembly.
•The globe support assembly disengages after approximately 3 turns. *Replace the lamp with one of the correct
size and type. Refer to the fixture nameplate for this information. When relamping, be careful not to damage the
threaded areas of the fixture, as they maintain the fixture’s explosion proof properties. Clean the threads and
apply a thin coating of lubricant before reassembling.
•To maintain maximum light output, the fixture should be cleaned periodically. Maintenance procedures sometimes
require fixtures to be hosed down for good housekeeping.
•The supply circuit must be turned OFF and the fixture globe must be allowed to cool to the ambient room
temperature before cleaning. Only mild, non-abrasive cleaning agents should be used. These periodic cleaning
procedures are important to prevent the accumulation of dust and dirt which will impair the light output of the
fixture. The glass globe should be regularly inspected for scratches and chips and, if damaged, the entire globe
support assembly must be replaced.
