Step

Procedure
③
Press the interlocks (
④
and ) of the carrier module
into the carrier module.
Recommendation:
Avoid angle errors during in‐
stallation:
Before tightening the fixing
screw, you should latch sever‐
al carrier modules onto the rail
and connect them to one an‐
other with the interlocks.
In this way, the carrier mod‐
ules automatically align them‐
selves parallel to the rail.
Tighten the fixing screws
on the carrier module to the
rail.
When the screws are tight‐
ened, the position of the carri‐
er module to the rail is fixed
and cannot be changed by
latching of the next carrier
module.
