  To prevent electrical arcing and fire hazard, all cable connections and electrical wiring connections should be 

sealed against moisture. This includes the use of proper cable sealing kits and the moisture proofing of all 
wire connections. 

  The metal sheath/braid of the heating cable must be connected to a suitable ground path before electrical 

power is connected to this equipment. 

  Isolate electrical power supply before opening or removing the Wire Cover. 

  The enclosure cover must be secured with all screws provided to maintain the environmental ratings. 

  The main components used in this connection system may present a hazard from static electricity. Only 

surface cleaning with a damp cloth is acceptable. 

  Routine maintenance is required to maintain compliance with health and safety legislation: 

  Check that the cover gasket is in place and not damaged each time the enclosure is closed. 

  Check that all cover screws are in place and secure each time the enclosure is closed. 

  Check the security of all cable entries on a routine basis. 

  Check that all electrical connections are tight and secure on a routine basis. 

  Check for physical damage and replace as required. 

  This connection system is designed for use in areas subject to normal industrial levels of vibration. They are 

not designed for use in areas subject to intentional or extreme conditions of vibration.
