Failure to do so could result inpersonal injury or loss of life. See the product rating curve for wire gauge selection, ambient temperature and current restrictions.∫WARNING:Only authorized and qualified personnel should install and service the E-SAFE II Hybrid Power Switch. Failure to comply with these recommendationsmay result in damage to equipment and property and injury to personnel.Torque Guidelines:Properly torque line and load terminals to 2.25 nm (20 in-lbs).NOTE:Do not use an RC snubber on the temperature control command signal output. The leakage current througha snubber circuit can turn the E-SAFE II relay on, even when the command signal is off.SnubbersSnubbers Snubbers

U.L. Conditions of AcceptabilityApplications must be tested as described below for specificwire insulation or specific wire gauge sizes. Testsshall be performed in the end application under worstcaseoperating conditions.Test ProcedureA. Monitor the temperature of terminals, usingthermocouples between the ring terminal andconnectors L1, L2 or L3. The temperature mustnot exceed 95°C.B. Monitor the temperatures of wire insulation,using a thermocouple located 3 inches from theconnector. The temperature must not exceed theinsulation rating of the wire.ç∫WARNING: Thermocouples attached to terminals will be at loadvoltage potential, measurements need to be taken with isolatedequipment or isolate the sensor from the terminal with suitableinsulation.These ratings apply to 3-phase units with cycle times of 30 secondsor more. Consult the factory for 1- and 2-phase unit ratings.ç∫WARNING: Wiring must conform to National Electric Code (NEC)safety standards, as well as locally applicable codes. Failure to doso could result in personal injury or loss of life.See the product rating curve for wire gauge selection, ambient temperatureand current restrictions.∫WARNING: Only authorized and qualified personnel should installand service the E-SAFE II Hybrid Power Switch. Failure to complywith these recommendations may result in damage to equipmentand property and injury to personnel.ç∫WARNING: Do not use an ungrounded wye- or delta-wired heaterconfiguration at 400 or 480VÅ (ac).Failure to follow all specifications and wiring instructions may resultin property damage, personal injury and/or loss of life.çCAUTION: Provide proper enclosure ventilation to maintain an operatingenvironment less than 70°C (158°F) maximum ambient rating.Failure to do so could cause damage to equipment and property.Torque Guidelines:Properly torque line and load terminals to 2.25 nm (20in-lbs).Unit DimensionsSide6.35 mm(0.25 in)Top46.99 mm(1.85 in)23.88 mm(0.94 in)82.55 mm(3.25 in)97.03 mm(3.82 in)14.88 mm(0.586 in)48.51 mm(1.910 in)140.72 mm(5.54 in)#10-32 (7x)1/4 x 0.032male Q.D.
