Passive clamps:
Measurement of the earthing resistance between clamp jaw and ground
(PAL):
ground clamp 70SG or 70PG:
earthing resistance: 235 kOhm, ±5 %
clamping force:
140 N, ±20 %
ground clamp 70OK or 70PK:
earthing resistance: <1 Ohm
clamping force:
100 N, ±20 %
5.2 Ground clamps
To make sure that the proper ground connection exists with the equipo-
tential bonding and that no malfunctions occur in active clamps, the
ground clamp must be cleaned when dirty.
Store the ground clamp such that it cannot be damaged. Replace
damaged cables and clamps with new parts. Whenever possible, the
ground clamp should either be hung up freely or be clamped to a non-
conductive object.
5.3 Cable rewinders
Perform regular checks to ensure that the cable and the insulation show
no tears or abrasion that could impair the cable's insulation or functioning.
Clean the cable with a cloth soaked in warm water to remove dirt or
incrustations and ensure perfect unwinding.
Defective devices must be sent in for repair.
