IMPORTANT NOTES PLEASE READ THE ENTIRE PAGE BEFORE PROCEEDING Make sure the serial number on the operator limit switch cover matches the serial number on the electrical enclosure cover. Verify that the classification of the hazardous atmosphere for this installation does not exceed the operator rating. Refer to the manual cover for the model rating; see page 3 for examples of hazardous atmospheres. Verify that the power available matches the rating marked on the operator nameplate.
CLASSIFICATION OF HAZARDOUS ATMOSPHERES Class Division Group Typical atmosphere/ignition temps. I Gases, vapors 1 Normally hazardous A acetylene (305C. 581F) B butadiene1 (420C. 788F) ethylene oxide2 (429C. 804F) hydrogen (520C. 968F) manufactured gases containing more than 30% hydrogen (by volume) Propylene oxide2 (449C. 840F) Acetaldehyde (175C 347F) cyclopropane (503C. 938F) diethyl ether (160C. 320F) ethylene (450C. 842F) unsymmetrical dimethyl hydrazine (UDMH) (249C. 480F) acetone (465C.
INSTALLATION WIRING 1. Install the operator motor and frame assembly according to the Owner's Manual for your model operator, (either GT or GJ). 2. Securely attach the electrical enclosure to the wall, adjacent to and within sight of the door and operator. See Figure 1. The operator has been factory wired for Type B2 as standard (momentary contact to open, close and stop). Diagrams to convert the operator to Type C2 are included (momentary contact to open and stop, with constant pressure to close).
