The Larson Electronics EPL-TX-8A-EPO-24V-25-EPP explosion proof stepdown transformer converts commonly used
120-277V AC electrical current to 24V DC at 8 amps. This converter is designed to be hardwired into electrical supplies
where the voltage is typically within the 100-277V AC range and steps it down to 24V DC, allowing operators to use
standard AC power to operate equipment that require 24 Volt DC current.
WIRING
Warning: Check product label for correct input voltage!
Secure each pair of wires according to the diagram. Utilize a junction box or
similar device and take precautionary steps for weatherproofing all
connections if installed in a location where water may come in contact with the
unit. Ensure the unit is properly grounded and that wiring is done according to
all local and national electrical/building codes.
We strongly encourage a licensed electrician install this product,in all locations especially in outdoor areas
where weatherproofing may be required. Universal voltage driver permits operation for primary voltage at 120-277V
AC, 50/60Hz, and secondary voltage at 24V DC.

Exp Cord Cap
Position device near work area for operation. Run cable to nearby power
source. Insert and twist-lock explosion-proof plug into a compatible receptacle within
the hazardous environment. See plug operation below.
PLUG OPERATION
Electrical connection between plug and compatible receptacle is accomplished
after plug fully inserts into receptacle and rotated clockwise.
1. Lift receptacle door and locate polarization on mating plug pin and
receptacle face. Insert plug straight all the way into receptacle until it
cannot go further.
2. Rotate plug clockwise limit (37º), this closes internal contacts and
completes circuit. This also mechanically locks plug into receptacle so it
cannot be pulled out.
3. To remove plug, push plug inward and turn to counterclockwise, pull plug
straight out.
Low Voltage DC
Connect power to power supply outputting low voltage at 24 Volts DC. This
variable voltage allows greater versatility without affecting light output. Ensure
deutsch connectors are properly connected (If applicable)
INSTALLATION
Unpack enclosure.
Run wire through EYS and cord grips on each end.
Make electrical connections following all state, local, NEC codes and all protocols for the
hazardous area. See labels attached to wiring for both Input and Output leads.
Refer to next page for sealing junctions.
If removing cover, make sure there are no loose or pinched wires when closing cover.
Replace and tighten all screws removed before.
MAINTENANCE
Electrical and mechanical inspection of all components must be performed on a regularly scheduled basic, determined by the
environment and frequency of use. It is recommended that inspection be performed a minimum of once a year.
USE AND CARE

EYS INSTALLATION / SEALING COMPOUND
HAZARD WARNINGS: May cause irritation to eyes and skin. Inhalation dust is considered a nuisance
dust. Avoid physical contact by wearing appropriate gloves and dust goggles. If powder gets into eyes,
flood immediately for 15 minutes with water. Wash hand thoroughly with soap and water after
handling
Mix 2 parts Sealing Compound to 1 part clean
water. Mix thoroughly. Do not mix more than
can be used in 15 minutes. Use cold water as
warm water accelerates set.
Vertical Installation:
Seal fitting is installed with the small access plug in the
up position. Both access plugs are removed after
conductors are installed. Damming fiber is installed
through the lower access port into the lower portion of
the fitting body. Care must be taken to insure the fiber
fills all voids around each conductor, as well as between
conductors and the wall of the seal fitting body. Replace
the lower (large) access plug. Mix compound according
to manufacturer instructions and pour through the upper
(smaller) access port until compound reaches the base
of the access port threads. Replace remaining plug in
upper access port. Both plugs are to be made up with
five threads engaged and wrench tight.
Horizontal Installation:
Seal body is installed with both access plugs in the up
position. Both access plugs are removed after
conductors are installed. Damming fiber is installed
through the large access port into both ends of the seal
fitting body to allow sealing compound to flow to the
required thickness (Table A). Care must be taken to
insure the fiber fills all voids around each conductor, as
well as between conductors and the wall of the seal
body.
Replace the small access port plug. Mix compound
according to manufacturer instructions and pour through
the large access port until compound reaches the base
of the access port threads. Replace large plug. Both
plugs are to be made up with five threads engaged and
wrench tight.
Class I Group A & B Installations:
Vertical Installation:
Sealing compound is to be mixed at ambient
temperature above 40°f. / 4°c. and poured into fitting
with body temperature not below 40°f. / 4°c. Ambient
temperature (of fitting) must not drop below 40°f. / 4°c.
for 72 hours. Compound must cure for 72 hours before
circuits are placed into service.
Horizontal Installation:
Sealing compound is to be mixed at room temperature,
and poured into fitting at room temperature. Ambient
temperature of fitting must remain at room temperature
for 72 hours. Compound must cure for 72 hours before
circuits are placed into service.
Class I Group C & D Installations:
Sealing compound is to be mixed at ambient
temperature above 35°f. / 2°c. and poured into fitting
with body temperature not below 35°f. / 2°c. Ambient
temperature (of fitting) must not drop below 35°f. / 2°c.
for 8 hours. Compound must cure for 8 hours before
circuits are placed into service.
