HAZARDOUS ATMOSPHERE, CONDUIT RUNS MUST HAVE A SEALING FITTING CONNECTING WITHIN 18 IN. OF
THE ENCLOSURE.
WARNING: FOR PRODUCTS MARKED AS TYPE 4X, USE TYPE 4X HUB FITTING; FOR IP66 USE IP66 HUB FITTING.
CAUTION: IF THE UNIT WAS SUPPLIED WITH A GASKET, AVOID FOLDING, CUTTING OR TEARING THE GASKET.
DAMAGING THE GASKET CAN ALLOW MOISTURE TO ENTER THE ENCLOSURE AND DAMAGE THE UNIT.
CAUTION: TO REDUCE THE RISK OF IGNITION IN HAZARDOUS ATMOSPHERES, DISCONNECT THE EQUIPMENT
FROM SUPPLY CIRCUIT BEFORE OPENING. KEEP ASSEMBLY TIGHTLY CLOSED WHEN IN OPERATION.

GENERAL SAFETY
When using electrical equipment, you should always follow basic safety precautions, including the following:
•
The installation and wiring of this product must comply with all national, federal, state, municipal, and local
codes that apply.
•
Properly ground the enclosure to an adequate earth ground.
•
Do not modify any factory wiring. Connections should only be made to the terminals described in this section.
•
All connections to the LP II Series models must use conductors with an insulation rating of 300 V minimum, rated
for 212º F (105º C), a minimum flammability rating of VW-1, and be of appropriate gauge for the voltage and
current required (See Specifications).
•
Do not allow moisture to enter the electronics enclosure. Conduit should slope downward from the LP II housing.
Install drip loops and seal conduit with silicone rubber product.
DISCONNECT REQUIREMENTS FOR PERMANENTLY INSTALLED EQUIPMENT
A dedicated disconnecting device (circuit breaker) must be provided for the proper installation of the unit. If independent
circuits are used for power input and main relay outputs, individual disconnects are required. Disconnects must meet the
following requirements:
