Maintenance
Introduction
Safety switches are properly lubricated at the factory. However, periodic cleaning and
lubrication may be required. The maintenance interval between lubrications depends
on the amount of switch usage and the ambient operating conditions. The maximum
maintenance interval should not exceed one year for mechanical or current-carrying
parts.
For additional information, refer to publication NFPA-70B, “Standard for Electrical
Equipment Maintenance”.
Unusual Performance Conditions
Contact Schneider Electric for information regarding performance under unusual
conditions. Examples of unusual conditions are shown in table below:
Unusual Conditions
Ambient temperatures below -22°F (-30°C) or above 104°F (40°C)
Altitudes over 6600 ft (2012 m)
Corrosive or explosive environments
Abnormal vibration, shock, or tilting
Unusual operating duties
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe electrical
work practices. See NFPA 70E, CSA Z462 or NOM-029-STPS.
• This equipment must only be installed and serviced by qualified electrical
personnel.
• Never operate energized switch with door open.
• Turn off switch before removing or installing fuses or making load side
connections.
• Always use a properly rated voltage sensing device at all line and load fuse clips
to confirm switch is off.
• Turn off power supplying switch before doing any other work on or inside switch.
• Do not use renewable link fuses in fused switches.
Failure to follow these instructions will result in death or serious injury.
Annual Maintenance Procedures
1. Turn off power supplying the switch before performing any work on or inside the
switch.
2. Open the switch blades by moving the operating handle to the OFF (O) position.
3. Lock out or tag the switch, per local procedures.
4. Open the enclosure door.
5. Always use a properly rated voltage sensing device at all line and load-side lugs
(terminals) to confirm power is off.
NOTE: Do not remove any parts from the switch or operating mechanism
unless specifically instructed to do so in the following procedures. Vacuum
any loose material from inside the switch. Wipe internal parts and the inside
of the enclosure with a damp, lint-free cloth.
