Installation guidelines
Semi-annual inspection
At least twice yearly, perform a thorough
inspection of the switchgear. Emphasize the
following checks:
• Perform an overall visual inspection.
• Check all indicators, meters and instruments
for proper operation.
• Make sure all bolted panels are secure.
• Verify operation of heaters and thermostats,
if used.
• Check for undue noise or vibration that might
loosen bolted connections.
• Look for evidence of moisture in the switchgear.
Annual inspection
• Bolted connections should be tight.
Discoloration, excessive corrosion, embrittled
or discolored insulation may indicate an
overheated connection.
• Inspect all cables for tight connections and
ample support.
• Inspect control wiring for signs of wear and
damage. Replace wires if signs of wear or
damage.
• Examine resistors and other devices prone
to overheating.
• Open all hinged panels and remove all
bolted panels.
• Clean insulation thoroughly.
• Withdraw and clean all drawout components.
• Clean the stationary portion of the switchgear by
wiping with a clean cloth.
• Compressed dry air is useful for cleaning
inaccessible areas.
• Remove covers of all panel devices where
possible. Check wiring for secure connections.
Clean contacts on relays and switches wherever
necessary. Replace covers.
• Inspect the gearing of the overhead lifting device
when used. Keep well lubricated. In very dirty or
gritty conditions, use a dry lubricant.
• Follow the recommendations of any individual
device instructions furnished for maintenance of
the device.
18-to-36-month inspection
Perform the following at 18- to 36- month intervals,
or sooner if required by local conditions or
regulations.
Clean the circuit breaker primary contacts. See
document 1SDH000999R0002 & SDH001000R0002
Listed breaker installation, service and
maintenance instructions. Inspect for evidence of
excessive heat, arcing, or corrosion.
