Check After Prolonged Storage
Storage Conditions
Devices must be stored in a dry, ventilated room, protected from rain, water and chemical agents.
They must be well protected against dust, rubble, paint, for example.
If storage is for an extended period, the relative humidity in the room must be maintained below 70%.
Storage conditions:
-
Devices without their trip unit: -40 °C to +85 °C (-40 °F to 185°F)
-
Devices with their trip unit: -25 °C to +85 °C (-13 °F to 185°F)
Devices must be stored in the open (OFF) position with the charging springs discharged.
Check and Maintenance
After extended storage and if the conditions above are respected, the checks below must be carried out to ensure correction device operation.
Storage ≤ 2 years
Run the second year and Intermediate End-User preventive maintenance programs on the following subassemblies:
-
Mechanism
-
Device and chassis locking
-
Chassis (optional)
Storage > 2 years
Run the fifth year diagnostic Intermediate End-User and Manufacturer preventive maintenance programs on the following subassemblies:
-
Mechanism
-
Control auxiliaries
-
Device and chassis locking
-
Chassis (optional)
If the devices are stored under harsh conditions (high temperature, corrosive atmosphere), it is necessary to:
-
Check the surface condition of the metal parts (zinc) and the copper parts (silver coatings (Ag) or tinning (Sn)).
-
Check the greasing for the device and chassis.
