Installation of the transparent insulating plate (addition E55 or E65, optional)
The transparent protective plate is an accessory and depends on the design of the
switching device. You can ask the manufacturer if mounting is possible.
The transparent insulating plate (65) is required at a rated short-term power frequen-
cy withstand voltage of 55 kV and 65 kV.
• Remove cover (see “Removing and mounting covers” page 40).
• Remove fixing material, fast-acting glue and installation drawing from the sup-
plementary equipment.
• Remove the protective film from the insulating plate.
• Insert M6 hexagonal bolt (polyamide) with washer through a hole in the trans-
parent insulating plate, screw on with spacer sleeve on the back and secure
hand-tight.
• Repeat the work steps for all other holes.
• Guide the fully assembled insulating plate between the pole shell and the oper-
ating mechanism housing, position it on the angled protective plate and then on
the operating mechanism housing (20).
• Fasten washers and M6 hexagonal bolts with a tightening torque of 1 Nm on the
M6 hexagon bolts.
• Secure the M6 hexagon nuts with fast-acting glue from the supplementary
equipment.
• Mount cover (see “Removing and mounting covers”, page 40).
