3.0 Maintenance
The IR10 and PP10 require minimal routine maintenance in normal day to day operation. Before inspection, the
device must be de-energized an locked out of service. Failure to do so could lead to personal injury or
death, as a result of shock.
Once the device has been de-energized, remove the cover. Visually inspect the wiring connections for looseness
and re-tighten where required. Inspect all internal wiring for wear and replace where required. In the event of
device or component (individual switch) failure, replacement of affected components should only be carried out by
ABB service personnel or sent back to the factory for replacement or repair. Contact the Service Department to
initiate all claims requests.
WARNING!

Generally, the only component that may require replacement is the K1 relay. Use only identical replacement relay,
as substitution of components that may affect the safety of the unit.
