Power Connector
The ANR2 accepts 24 Vdc as its input power. As shown in the figure below, the power connector is located

AMCI under the part number MS-4M. They are also available from Phoenix Contact under their part number
187 80 37.
Figure 3.4 Power Connector Location
Power connections should be tight, as loose connections may lead to arcing which will heat the connector.
Phoenix Contact specifies a tightening torque of 4.4 to 5.4 lb-in (0.5 to 0.6 Nm).
The power supply is connected to the pins marked “+Vdc In” and “DC Return”. The “Chassis GND” pin is
used to attach the ANR2 to earth ground.
1) AnyNET-I/O modules are electrically isolated from the DIN rail by their mounting, but the
Chassis GND connection is common to all of the modules in the stack through a pin in the
IC-5 connector. At least one module in the AnyNET-I/O Stack must be attached to earth
ground through a heavy gauge stranded wire to ensure reliable operation of the stack.
2) Each ANR2 module must have its own power connection.
I/O Connector Pin Out
The I/O Connector is located on the top of the module. The mate for this connector is included with the
ANR2. Spares are available from AMCI under the part number MS-2X11 and are also available from Phoe-
nix Contact under their part number 173 88 98. Figure 3.5 shows the pin out for the I/O connector.
