Connection Examples
Connection with line derivation:
supply wires
Mot a / Mot b
derive off in par-
allel,
monitoring
will be looped through all
cables up to group end.
Example 1:
1 line
Simple installation, but unfavourable for
voltage drop: All drives on one line.
Example 2:
2 lines
Control panel in centre, one side wired as
derivation, the other as terminal line.
Observe 4 wires for derivation!
Example 3:
2 lines on one side
Derivation and terminal lines in same
direction; number of drives vary according
to length of line.
Observe 4 wires for derivation!
Example 4:
3 lines
3 lines are installed due to extremely long
distances: 2 lines with 3 drives each on 75
m line as derivation, and 1 line with 2 drives
on 200 m line.
Observe 4 wires for derivation!
