5.3 Control Supply Module

5.3 Control Supply Module
5.3.1

Description

The Control Supply Module is a 24 V power supply with 20 A output current.
The output voltage corresponds to protective extra low voltage (DVC A) with grounded
frame.
The power is either supplied via the line supply connection or the integrated DC link
connection. For example, this means that it is possible to maintain the 24 V power supply
voltage when the power fails for coordinated retraction motion.
Input voltage range: 320-550 V
When the Control Supply Module is first operated, then the power is always taken from the
line supply. When the power fails, the module automatically changes-over to supply from the
DC link.

Safety information

This component is equipped with two supply circuits!
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 (e.g. with a defective lock on the protective cover) must not be
operated further.
Failure to comply with these instructions can result in death or severe injury.
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.
A ventilation clearance of 80 mm above and below the components must be observed.
