Lubrication Instructions

WARNING
hazard of incorrect maintenance Do not disassemble circuit-breakers and drives for lubrication. Only approved lubricants may be used. Refer to Auxiliary products. Failure to follow these instructions can result in death, serious injury, or equipment damage.

CAUTION
hazard of incorrect maintenance The following elements must not be lubricated: Motor Ball bearings Auxiliary releases Push switches Blocking coils Auxiliary switches Failure to follow these instructions can result in injury or equipment damage.

Preparation

Remove truck from the panel, refer to the Access to the Main Circuit Compartments and Removing the circuit breaker from the panel, Installation Manual (GEX2564100SWE-00(NORDICS)).
To get access to the fixed contacts behind the shutters, use a shutter lift (Figure 63).
Handling of the shutter lift corresponds to that of standard trucks (Evopact HVX and EvoPact UTX).
Clean lubrication points using a lint-free cloth; use cleaning agent in case of serious contamination, refer to the Annex.

For a panel width of 650 mm, refer item number ADM I25 125-01.

For panel width 800/1000 mm, refer item number ADM I25 126-01.

Lubrication

Points of lubrication	Lubricant	Lubrication procedure
Sliding contact surfaces	KL	Clean by means of lint-free cloth; use cleaning agent in case of serious contamination. Apply a thin and uniform film of lubricant.
All accessible friction points and sliding surfaces	KL	Clean lubricating points using a lintfree cloth or a soft paint-brush, if necessary using cleaning agent (use sparingly, just moisten points of lubrication). Apply a thin coat of lubricant (using e.g. a paintbrush).
Bearings and joints	FL	Pour drops of liquid lubricant (oil can, drip feed lubricator) into the bearing gap. Liquid lubricant gets between the bearing surfaces due to the capillary effect. In case of inaccessible lubrication points, use an extension tube or spray.

Once maintenance work is complete:

Remove all the tools and auxiliary equipment used.
Reinsert truck into the panel, refer to the Access to the Main Circuit Compartments and Inserting the circuit breaker into the panel, Installation Manual (GEX2564100SWE-00(NORDICS)).
Reposition covers, close doors and check switching functions, refer to the Commissioning, Installation Manual (GEX2564100SWE-00(NORDICS)).
