Restrictions
Risk of electrical shock
The DC link within the Power Module (PM) carries high voltages which has the potential to
cause severe personal injury.
Before performing any installation work on the system, it is essential that all power supplies
to the system are disconnected.
After the power supplies have been disconnected from the system, it is necessary to wait
for at least five minutes before accessing any electrical connections of the system, this
allows time for the high voltage capacitors within the system to completely discharge.
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.
