Installation
4.2 System Installation
At the base of the 24 V PSU housing is a cable gland opening (which is sealed with a blanking
plug) which provides and entry point for the cables from an external braking resistor.
The optional 24 V PSU can be ordered using the following article number:
6SL3555-0PV00-0AA0
A brief description of the layout and the connections of the 24 V PSU are given in the following
figure.
Figure 4-6
Restrictions
The following restrictions should be observed when installing the 24 V PSU:
• If an external braking resistor is not used, the cable gland opening must be sealed with a
blanking plug to maintain the IP rating of the system.
• The 24 V DC IN and OUT connectors and the CPI must be sealed with screw caps to maintain
the IP rating of the system.
• When using the 24 V PSU there is no longer any isolation between the 24 V PSU and the digital
outputs of the system.
• Since the 24 V PSU utilizes the DC link voltage to provide the 24 V supply to the Control
Module, when the mains supply is disconnected, all power will be lost to the Control Module.
