3.3.7.2 Connecting to the DC Power Supply
The device is supplied with two PEM modules. Each PEM module is equipped with a DC
power inlet (Phoenix Contact type MSTB2.5/2-STF, 5.08 mm). The DC input is floating with
a maximum input current of 5.25 A.
Depending on customer requirements, the power cabling is available in one of the following
configurations:
DC terminal block with a screw connection type: the device is provided with a pre-
installed terminal block in the chassis (DC inlet). This terminal block must be used with
14-AWG wires for connecting to the DC mains.
DC terminal block with a crimp connection type: the device is supplied with a 48-
VDC power feed cable crimped to this terminal block. The connector types that
constitute this connection is as follows:
• Phoenix contact type crimp terminal female 14-16 AWG (P/N: STG-MTN 1,5-2,5)
• Phoenix female terminal block shroud 7.62 mm 2 pole cable mounting (P/N:
PCC4/2-ST-7,62)
Electrical Caution
Before crimping the power wires to the terminal blocks, ensure that the power
wires are not connected to the DC mains.
