Maintenance
!
WARNING
Electrical power must be turned OFF before and during installation and maintenance. Failure to do so may result in serious or fatal
injuries due to electrocution.
The receptacle must be inspected regularly. Schedule of inspections is determined by frequency of use and environmental conditions.
We recommend that inspections be carried out at least once a year and that an electrical preventive maintenance program (e.g. National
Fire Protection Bulletin NFPA No. 70B) be followed in addition to the steps below.
During the inspections, perform the following steps:
1.
Inspect/ensure that all conductor terminations are secure. Re-torque to values given previously in these instructions if necessary.
NOTE:
Discoloration due to excessive heat is an indicator of possible problems and should be investigated and repaired as necessary.
2.
Check grounding and bonding effectiveness/continuity. Re-torque connections to original values if necessary.
3.
Check gaskets for damage and replace as necessary.
4.
Inspect breathers and drains for proper function. Clean or replace as necessary.
5.
Check all conduits and close-up plugs for tightness and re-torque as necessary.
6.
Clean interior of all foreign materials.
7.
Make sure all openings are closed.
8.
Cover bolts must be tightened AND the cover locking screw engaged inside the cover.
9.
Make sure the receptacle assembly nameplate remains clean and legible.
Do not paint the nameplate.
NOTES:
• The receptacle insulator and contacts are not serviceable; consult with the factory.
