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
