Primary part
General, Preparation
The following regulations must be adhered to during installation, commissioning and operation:
· IEC 60694/DIN VDE 0101, General specification for high-voltage switchgear and control gear standards.
· VDE 0105, Operation of electrical installations.
· DIN VDE 0141, Ground systems for electrical power installations with nominal voltages above 1 kV.
· All rules for accident prevention applicable in the respective countries.
The wearing of gloves for handling the parts during installation
is recommended.
Insulating material surfaces must be cleaned with clean and
dry rags. The contact surfaces of connections must be cleaned
before installation. If the contacts have become oxidized
during transport or storage then the following sequence must
be followed:
· Clean contact surfaces with a rough, dry cloth.
· With hard oxidation, clean with a hard plastic sponge,
the upper layer must not be removed.
For ISM fixing and terminal connections steel bolts according
to EN ISO 898 class 8.8 (800 N/mm²), nuts according to EN
ISO 890 class 8 (880 N/mm²), washers to DIN 125 and conical
spring washers to DIN 6796 shall be used.
ISM mounting and connection shall be made with dynamometic
wrench only.
Ins tallation of the ISM
In any switchgear application, the ISM shall be installed with
the actuator drive axis vertical (Figure 16). ISM may be
installed in position “actuator up”, as well “actuator down”
(for all types).
The ISM shall be installed at the place designated for it on a
sufficiently stable frame. In order to prevent bending loads
at the support insulators the poles must be fixed as shown in
figure 20. The torque of all fixing points shall not exceed the
values stated in figure 20.
