Power
Supply Connection:
Power Supply is 24 VDC, with conductor size AWG 12-13 (2.5
– 4 mm²). The Interconnection boards of
master and slave units are connected to the connector J14. It is a 3-pin plug connector, but only two-wire
connection (+ and -
) are needed. Don’t connect a third wire for the ground. Instead of that the devices should
be grounded at the bottom of each housing at a M5 connection or at a free M8 connection at the mounting
plate.
