● 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.
Installation
1. Disconnected all power supplies to the system and wait 5 minutes.
2. Remove the Power Module (PM).
3. Remove the blank plate from the side of the terminal housing.
4. Remove the Control Module (CM).
5. Fit the 24 V PSU to the side of the terminal housing, ensuring that no cables or wiring are
trapped between the 24 V PSU and the terminal housing. Tightening torque: 1.5 Nm.
6. Connect the input cable to the DC link terminals in the terminal housing (black to DC- and
red to DC+).
7. The 4-way 24 V cable is routed underneath and then over the top of the CM.
8. Fit the 4-way connector as shown in the illustration below.
9. Fit the CM back into place - ensuring that it securely fastened into place.
10.Replace the PM.
11.Fit blanking cap to the 7/8th connector (note: there is no 7/8th connector on the USS
