ISM Installation
General, Preparation
All applicable regulations must be adhered to during installation, commissioning and operation, including
ANSI, IEEE, CEC, NEC, and other local, national or international standards / codes as required. Work shall
only be performed by qualified personnel.
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.
Nuts, washers and conical spring washers shall be used for
connecting the upper terminals of the ISM with the busbars.
The lower terminals of the ISM shall be connected with the
same connecting elements.
If additional fastening material is required, 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
All LD series can be installed in any position (Figure 21). The ISM
shall be installed at the place designated for it (Figure 21) on a
sufficiently stable frame.
In order to prevent bending loads at the support insulators the
poles must be fixed as shown in Figure 22.
The torque of all fixing points shall not exceed the values stated
in Figure 23.
