figure 4: Multi connector for IO (Power Supply Pins highlighted)
A suitable mating connector with lock-and-release levers is Phoenix Contact order number 1790580. A
Model witch screw locking is available with order number 1790399.
The plug uses spring-cage connection and accepts solid or flexible wires from 0.2 mm² to 1.5 mm².
Push in connection is possible, in case of flexible wires you must use ferrules for this. If you use
ferrules with plastic sleeve, the maximum wire size reduces to 0.75 mm².
Stripping length for the wires is 10 mm.
If you use ferrules, obey that standard ferrules for 0.75 mm² have only 7 mm length.

DANGER
The product may only be operated with power supplies which can be considered SELV
circuits.
Pins 21 and 22 should be connected to EMI protective earth (PE). These contacts are internally
connected to the DC power supply EMI filter and to the D-SUB shell of the console (RS-232). The
signal is doubled to prevent false connection, it only requires one connection. In locations where no
EMI noise is present, the PE connection is not required. The PE has no safety function.
