WARNING
TO AVOID THE RISK OFFIRE, EXPLOSION OR ELECTRIC SHOCK, THIS PRODUCT SHOULD BE INSTALLED,
INSPECTED AND MAINTAINED BY A QUALIFIED ELECTRICIAN ONLY, IN ACCORDANCE WITH ALL
APPLICABLE ELECTRICAL CODES.
TO AVOID ELECTRIC SHOCK:
•BE CERTAIN ELECTRICAL POWER IS OFF BEFORE AND DURING INSTALLATION AND MAINTENANCE.
•PRODUCT MUST BE CONNECTEDTOA WIRING SYSTEM WITHAN EQUIPMENT-GROUNDING
CONDUCTOR.
TO AVOID EXPLOSION:
•MAKE SURE THE SUPPLY VOLTAGE IS WITHIN THE VOLTAGE RATING.
•ENSURE THE MARKED T RATING IS LESS THAN THE IGNITION TEMPERATURE OF THE HAZARDOUS
ATMOSPHERE.
•DO NOT OPERATE IN AMBIENT TEMPERATURES ABOVE THOSE INDICATED ON THE PRODUCT
NAMEPLATE.
•DO NOT OPERATE IF THE LENS, CORD, SEALS, HOUSING, RECEPTACLES, ETC. IS CRACKED OR
DAMAGED. IF SO, DISCONTINUE USE AND CONTACT MANUFACTURER FOR REPLACEMENT PARTS.

The EPL-TL-1X10W-C-PA-XFSW Explosion Proof Signal Light w/ Audible Alarm and External Float Switch from Larson
Electronics is suitable for monitoring liquid levels inside flammable work sites. The ATEX-rated system provides visual
notification via an LED strobe lamp and audio notifications via an audible horn. Constructed of 316 stainless steel, the
external float switch operates magnetically and is capable of withstanding 2,000 psig (138 bar) of pressure.
SIGNAL LIGHT AND HORN INSTALLATION
We recommend only a licensed electrician install this product!
It is strongly suggested to use two licensed electricians to proceed with the
final mounting of the fixture to avoid any possible personnel injury or damage
to the fixture. Depending on mounting height and scaffolding, a hydraulic man–
lift or two good quality ladders should be used. This fixture is heavy and must
be mounted to a surface that can structurally support the load. Secure the unit
firmly to the surface by lifting the unit into place, and driving appropriate
mounting hardware through all pre-drilled mounting holes in the side flanges of
the back plate. Failing to comply can result in breakage, allowing the fixture to
fall, which can cause serious injury or death. Run 3/4" conduit to the junction
box and wire the unit according to the wire diagram included with your unit.
Unit should be installed and wired in accordance with all applicable NEC and
local electrical/building codes. Wiring for the signal light and horn are
accessible via the junction box at the base of the light fixture.

FLOAT SWITCH INFORMATION AND INSTALLATION
Rugged and reliable, the float switch operates automatically to indicate tank level. Perfect for starting or stopping pumps,
opening or closing valves, or actuate level alarm signals. A unique magnetically actuated switching design gives superior
performance. There are no bellows, springs, or seals to fail. Instead, the free-swinging float attracts a magnet within the
solid metal switch body, actuating a snap switch by means of a simple lever arm. Float arm hinge design limits the arm
angle to prevent vertical hangup.

NOTES:
•Check all ratings given in the instructions and on the product to make sure that the product is suitable for your
application. Do not exceed electrical ratings, pressure ratings, or temperature ratings of the product.
•Disconnect power supply before beginning installation to prevent possible equipment damage or electrical shock.
1. Remove packing material from switch body-cap and remove tape from magnet keeper. Install standard switch in
thredolet previously welded to tank. Install optional switch mountings per application drawings. Make sure locknuts
on float are tight.

ATEX and IECEx Installation Instructions:
Cable Connection
The cable entry device shall be certified in type of explosion protection flameproof enclosure “d”, suitable for conditions of
use and correctly installed. Cable entry may exceed 70°C. Conductors and cable gland rated ≥95°C shall be used.
Conduit Connection
An Ex d certified sealing device such as a conduit seal with setting compound shall be provided immediately to the
entrance of the valve housing. Cable entry may exceed 70°C. Conductors and cable gland rated ≥95°C shall be used.

4. Make sure conduit or cable are properly sealed. Electrical components must be kept free of moisture, including
condensation, at all times.
CAUTION: To prevent ignition of hazardous atmosphere, disconnect the device from the supply circuit before opening.
After de-energizing, delay 10 minutes before opening. Keep assembly tightly closed when in operation.
NOTE: ATEX and IECEx units only: The temperature class is determined by the maximum ambient and/or process
temperature. Units are intended to be used in ambient of -20°C ≤Tamb≤73°C. Units may be used in process
temperatures up to 133°C providing the enclosure and switch body temperature do not exceed 73°C. The standard
Temperature Class is T6 Process Temp ≤73°C.
5. For units supplied with both internal ground and external bonding terminals, the ground screw inside the housing must
be used to ground the control. The external bonding screw is for supplementary bonding when allowed or required by
local code. When external bonding conductor is required, conductor must be wrapped a minimum of 180°about the
external bonding screw. See below.
MAINTENANCE
Inspect and clean wetted parts at regular intervals. The cover should be in place at all times to protect the internal
components from dirt, dust, and weather, and to maintain hazardous location ratings. Disconnect device from the supply
circuit before opening to prevent ignition of hazardous atmosphere. Repairs to be conducted by Larson Electronics, Inc.
Units in need of repair should be returned to the factory.
