7.7 Spare parts, auxiliary materials and lubricants
7.7.1 Spare parts
A spare parts list is available on request for procurement of spare parts. It basically includes moving
parts and parts subject to wear. When parts are required, the serial number of the relative switchgear
or switching device should always be quoted.
7.7.2 Auxiliary materials, lubricants
Lubricant
• Vaselina as oxidation protection for busbars;
• Mechanical grease for moving parts.
Halogen-free cleansers
• ETHANOL F 25 M (for general cleaning);
Touch-up paint
• Standard colour RAL 7035.
7.6 Tests on the panel
7.6.1 Auxiliary switch settings on the earthing switch
1. There must be a run-on of 0.5 mm in the fully operated position before the plunger reaches the stop
(for safety reasons);
2. Auxiliary limit switch 11.4 (Q8S2) for earthing switch ON must be operated immediately after the
dead centre position of the toggle spring mechanism is reached in the closing process and the
automatic rapid closing process has started;
3. Auxiliary limit switch 11.3 (Q8S1) for earthing switch OFF must:
a) be operated on earthing switches with manual mechanisms during the opening movement of the
slide 14.2 before half of the hexagonal shaft has become visible, or 1 mm before the tab of the
slide makes contact with the armature of the de-energised locking magnet;
b) be operated on earthing switches with motor operators (no slide 14.2 fitted) immediately after the
toggle spring mechanism has passed the dead centre position during rotation to the OFF position.
Note
Check the direction of rotation of the motor after repair work.
Do not allow the motor to run up against a lock if the direction of rotation is incorrect (also see section
7.5.4).
