WARNING: 

READ CAREFULLY BEFORE INSTALLING FIXTURE. RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE. 

CRITICAL SAFETY INSTRUCTIONS: 

INSTALLATION SHOULD ONLY BE CONDUCTED BY A QUALIFIED ELECTRICIAN IN ACCORDANCE WITH NEC AND ANY

RELEVANT LOCAL BUILDING CODES.

RISK OF FIRE OR ELECTRIC SHOCK. FIXTURE INSTALLATION REQUIRES KNOWLEDGE OF 

FIXTURE'S

 ELECTRICAL

SYSTEMS. IF NOT QUALIFIED, CONTACT A QUALIFIED ELECTRICIAN.

BE CERTAIN ELECTRICAL POWER IS OFF BEFORE AND DURING INSTALLATION AND MAINTENANCE.

MAKE SURE THE SUPPLY VOLTAGE IS THE SAME AS THE

 FIXTURE'S

 RATED VOLTAGE.

TO PREVENT WIRING DAMAGE OR ABRASION, DO NOT EXPOSE WIRING TO EDGES OF SHEET METAL OR SHARP

OBJECTS. SUITABLE FOR DAMP LOCATIONS.

WARNING 

TO AVOID THE RISK OF FIRE, 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  CONNECTED TO A  WIRING  SYSTEM  WITH  AN  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.

ALL FASTENERS SHOULD BE PROPERLY SEATED.

The EPSW-TS-RTD-6P-R1 from Larson Electronics is an Explosion Proof RTD Temperature Transmitter for Class I, II 

and III rated locations. This low voltage unit contains a 6" stem/probe and features an LCD display. Protected by a NEMA 

4X rated 316 stainless steel housing, the transmitter offers seven pre-programmed temperature ranges.

WIRING 
Standard pigtail(flying leads) wiring 

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 at 10V  -

Warning: 

Check product label for correct input voltage!

 

Attach supply line wires to the appropriate light fixture wires as shown 

in the diagram 

 

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.
