WARNING

DO NOT DISCONNECT WHILE CIRCUIT IS LIVE UNLESS LOCATION IS KNOWN TO BE NONHAZARDOUS.

Live part of electric circuit or a high temperature department can cause explosion.

DON’T

Do not active live circuits While assembly of all components is not over.

Protective performance degradation for hazardous location can cause explosion.

DON’T

Install per the National Electrical Code for the US (NEC, ANSI/NFPA 70) and the Canadian Electrical code for Canada (CEC, CAN/CSA-C22.1) and the drawing 3S8A2532, 3S8A2676 and 3S8A2677 (Refer to Appendix 1.).
