ACM 400 S motor control unit
6 / 24
5) Installation
This requires 4 screws with a shank diameter of 4mm
a) The suitable installation location
The motor control unit is supplied as a printed circuit board in a simple plastic
housing [X11]. You should therefore choose an installation location with the following
conditions:
The
ambient temperature
may not be lower than -20°C and not higher than
+50°C.
The
air humidity
must lie within 30...90% RH.
Electromagnetic fields
at the installation site must be reliably shielded.
If you use the version with the integrated membrane keyboard, the installation
location should lie within a safe and secure
operator area.
b) Installation
The internal temperature rating is designed for
vertical installation
[X3], [X5],
whereby the
cables must be brought out at the bottom
and sealed with the
enclosed
threaded joints
to prevent penetrating moisture [X13].
The
weight
of the control unit is approx 1.7 kg. Please take this into account when
choosing the type of fixing.
Install
the control unit housing professionally at the suitable installation location.
6) Connect
You may only work on the control unit if it is disconnected from the
power supply!
203 or 400 Volt system voltages can be applied at terminals 1-18. Danger!
Never connect system (i.e. mains) voltage to terminals 19..42.
Disregarding the above causes immediate destruction of the control unit, and the
warranty expires!
Whenever you carry out any work on the control unit ensure
ESD compatible
earthing
. Otherwise there is a risk of the control unit being damaged or
destroyed.
For improved clarity, the respective setting options (values) are also described in this
chapter. The "Programming" chapter (see page 16) explains how you can call up the
necessary Settings menu.
The screw-type terminals 16...42 can be plugged in, you can easily pull them out
from the front. This should make it easier for you to connect the individual wire
strands/cores.
