of unfavorable operating conditions frequent temperature
changes the clamping points, shorter interval may be
necessary. Cupal washers are required for the transition
from aluminum cable lugs the busbar the terminal
blocks. For normal ambient conditions and load cases,
we recommend checking intervals six months. This selected according its conductor shape
and connected according the cable lug manufacturer‘s
specifications. Stranded aluminum conductors are
connected terminal blocks with the aid aluminum
cable lug. Temperature measuring strips with storage of
the maximum values can attached the immediate
surroundings the connection points and can useful
for objective assessment during the regular inspections. This the only way ensure safe transition from
copper aluminum.Installation
Assembly notes for flat cable lugs:
When tightening the terminals, recommended to
hold against the conductor avoid deformation the
mounting rail and keep the base the terminal block free
from torsional forces.

All connection points are suitable for the connection one
conductor, unless explicitly noted otherwise.
Aluminum conductor for indirect connection:
Indirect connection aluminum conductors the safest
choice. This can made possible crimped connection
elements such Al/Cu ring cable lugs crimp connection
bolts. Nevertheless, the corresponding manufacturer‘s
specifications must also observed here, and the connection
points must checked according the operating
conditions
