Motor Modules with internal air cooling

4.2.1

Description

A motor module is a power unit (inverter) that provides the power supply for the connected
motor(s). Energy is supplied from the Infeed Module. A Motor Module must be connected to
a Control Unit via DRIVE-CLiQ. The open-loop and closed-loop control functions for the
Motor Module are stored in the Control Unit.
One motor can be connected to single motor modules and two motors can be connected to
double motor modules.

Safety information

Risk of electric shock. A hazardous voltage is present for up to 5 minutes after the power
supply has been switched-off.
It is only permissible to open the protective cover after this time has expired.
When opening the protective cover for the DC link, you must activate the release.
A suitable tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used further, as this could result in secondary damage
or accidents.
Motor Modules with a rated current as of 18 A and all Double Motor Modules conduct a
high leakage current via the PE conductor. Because of the high leakage current of the
Motor Module, a permanent PE connection of the Motor Module or control cabinet is
required.
Furthermore, the following measures must be taken according to EN 61800-5-1:
Either protective ground conductor cross-sections ≥ 10 mm
protective ground conductor of the same cross-section as the first one.
The DC link discharge voltage hazard warning in the local language must be attached to all
of the components.
A set of labels in 16 languages is supplied with the component.
