NOTICE
Cleaning
Possible malfunctioning and damage to the panels caused by pollution.
Before closing the busbar compartment:
Clean polluted areas. To do this, use a vacuum cleaner and a lint-free cloth.
If necessary, moisten the cloth, use a mild household cleaner, and dry
properly at the end.
Some parts and surfaces of the switchgear are greased for functioning. Do
not remove the grease there; do not clean the parts and surfaces.
If greased areas are dirty, clean the dirty area and grease again according
to the maintenance instructions.
INFORMATION
Before commissioning the panels, the busbar compartment must only be
permanently closed by bolting the transverse partition or busbar cover tight under
the following conditions:
•
The compartment is free from foreign objects and pollution
•
All previous assembly work inside the compartment has been fully and
properly completed
Verify completeness and correctness of the previous assembly work inside
the compartment. In this context, also check the control tightening torque of
the bolted joints and correct the torques if required.
Record the proper condition of the compartment after bolting together, so
that this is clear without any doubt before commissioning the panels.
INFORMATION
In the case of contactor panels with panel width 435 mm, the busbar compartment
is accessible neither through the rear wall of the busbar compartment nor through
the roof plate.
The busbars must absolutely be mounted from the side of the panel before
mounting the transverse partition.
