4.0 Wiring
In chapter 4.3 you will find the typical (minimum) wiring of the system . The following pages show some
special applications and the typical wiring in more detail.
This chapter is valid for all units.
For the system set-up it is necessary to wire the
system step by step.
It is recommended to follow the system set-up
procedure, especially for users who are not very
familiar with these drivers.

Wiring
4.1.1 Power Supply
The controller can be supplied, like shown below, with 1- phase input voltage. The power supply module
consists of rectification, smoothing, regeneration circuit and surge current protection.

1) Autotransfomer
2) Isolating transformer
3) Single phase connection (see also chapter 1 for input voltage)
4) The size of the fuse must fit in order to project the power of the transformer.
Fault current breaker are not permitted for fusing the drive (same for point 5).
5) Each controller is internally fused and therefore self protected. The shown input fuse is only for cable or
lead protection. It is recommended to use a back-up fuse of 16A or 20A (max.); e.g. Neozed type gL slow
blow type). For a fuse size of 16A a lead diameter of up to 1.5mm² can be used and for a 20A fuse the
max. lead diameter has to be 2.5mm².
