MAINTENANCE
Electrical and mechanical inspection of all components must be performed regularly. It is recommended
that inspection be performed monthly. Lubricate threads periodically.
CAUTION
Electrical power supply MUST BE OFF before and during installation or maintenance.
DISCONNECT primary power source and LOCK OUT. Installation and maintenance
procedure must be performed by a trained and competent electrician.
• Inspect all contact wire terminals for tightness. Discoloration due to excessive heat is an indicator
of possible problems and should be thoroughly investigated and repaired as necessary.
• Check grounding and bonding for correct installation and secure connection.
• Check gaskets for deterioration.
• Clean exterior surfaces making sure nameplates remain legible.
• Inspect clamp guide assembly and cable grip tightness to ensure proper cable gripping.
• Inspect interior parts and replace those which are broken or excessively worn.
• Check all contacts for signs of excessive arcing or burning.
WARNING
If any parts of the plug, receptacle or connector appear to be missing, broken or show
signs of damage, DISCONTINUE USE IMMEDIATELY! Do not modify these devices in any
way. Replace with new device. Failure to do so could cause serious personal injury and/or
equipment damage.
An Electrical Preventive Maintenance Program as described in the National Fire Protection Association
Bulletin NFPA No. 70B is recommended in addition to these required maintenance procedures.
