ABB PM856 3BSE018104R1 Speed module

The MB20 expansion module can be installed while in running operation. □ On the right side of the switch basic module, loosen the screw at the top and at the bottom (1 - 3 revolutions). 

□ Remove the side cover. 

□ If you have not yet done so, mount the switch basic module onto the top-hat rail. 

□ Slide the MB20 expansion module on the top-hat rail toward the switch basic module until the modules plug into each other. □ On the switch basic module, tighten the screws at the top and at the bottom.

CONNECTING THE MM22-T1T1T1T1 POE MEDIA MODULE 

The MM22-T1T1T1T1 PoE media module is supplied with the PoE voltage (48 V DC safety extra-low voltage) via an external power supply unit. The PoE voltage is fed into the 3-pin terminal block of the PoE media module. The twisted pair cables are supplied with the PoE voltage on port 1 to 4 via the spare pairs (pins 4 & 5 and 7 & 8 of the RJ45 sockets).

Make sure that the external power supply unit

 being used for providing the PoE voltage meets, among other things, the following requirements: – Isolation requirements in compliance with IEEE 802.3af (electrical strength of the 48V output to “rest of the world" 2250 V DC for 1 min.) – Output power < 100 W. – Current limiting < 2 A. – Power supply unit and PoE media module form a “Limited Power Source” in compliance with IEC60950-1. – The external PoE power supply unit has to be able to provide the power for the PDs being connected. All these conditions are met by the RPS60/48V EEC power supply unit.
