4.1 Primary part
Preparation
The following regulations must be adhered to during installation, commissioning and operation:
IEC 62271-1//DIN VDE 0101, General specification for high-voltage switchgear and control gear
standards;
VDE 0105, Operation of electrical installations;
DIN VDE 0141, Earthing systems for electrical power installations with nominal voltages above 1 kV;
All rules for accident prevention applicable in the respective countries.
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 actions must be followed:
Clean contact surfaces with a rough, dry cloth;
In case of hard oxidation, clean with a hard plastic sponge, the coating layer must not be removed;
The nuts, washers and conical spring washers shall be used for connecting the terminals of the ISM with the
busbars.
If additional fastening material is required, steel bolts according to EN ISO 898 class 8.8 (yield point 800
N/mm
2
), nuts according to EN ISO 890 class 8 (yield point 880 N/mm
2
), washers to DIN 125, conical spring
washers to DIN 6796 (for ISM15_LD_1, LD_3, LD_6, LD_8 and ISM25_LD_1, LD_2, LD_3) and high load
conical spring washers (#431540 in Schnorr catalogue - for ISM15_MD and #431560 in Schnorr catalogue -
for ISM15_HD) shall be used. Bolts and washers for ISM15_Shell_2 connection are already included in the
CBkit_Shell15_1 kit. ISM mounting and shall be made with a calibrated torque wrench only.
Installation of the ISM
Mounting
In any switchgear application, the ISM15_Shell and ISM15_HD may be installed in position “actuator up”, as
well “actuator down” (Figure 58, Figure 59). The ISM15_LD, ISM15_MD and ISM25_LD can be installed in
any position (Figure 60). Additionally ISM15_Shell_2(150_L) and ISM15_Shell_2(210_L) can be installed in
horizontal actuator position. In this case the plane of all ISM terminals surfaces shall be horizontal as well and
terminals surfaces shall be up oriented.
