acc. to Fig. 228:
Panel versions with at least 3 connection points per phase
In panel versions with at least 3 connection points per phase, the connection points for cable sealing ends are
arranged both one behind the other and side by side (viewed from the access to the connection compartment).
Damage to the switchgear panels
Depending on the cable lugs used, the cable lugs of adjacent phases can
be too close to each other. Use only cable lugs keeping the minimum
distance between the cable lugs of adjacent phases.
The panel connections in the connection compartment must all be equipped
with cable sealing ends.
To bolt the cable sealing ends together with the cable connecting lug,
always use the bolting material pre-assembled at the connecting lug.
To coordinate a different procedure, please contact the regional Siemens
representative.
