Chapter 3 Electrical Installation
Auxiliary Power Connection Attach a micro-style 4-pin female to the micro-style 4-pin male receptacle as
shown below. The female side is used to daisy chain the power to another device.
The power connection is limited to 4 A. When the daisy chain approach is used,
the maximum number of interface blocks that can be connected is determined by
the total power consumed by each block.
The pin connections for the aux power connectors are shown below:
The power for the output port is separate from the power to the remaining
portions of the interface block. This allows the output device to be turned off,
while maintaining power to the transceivers, the input port, and the EtherNet/IP
connection. When the output is connected to the safety related portion of the
machine control system, an actuator can be turned off, while diagnostic
information is still available to the machine control system.
IMPORTANT Power must be connected to the male connector first. Do not connect power to
the female connector and leave the male connector exposed. The pins in the
male connector will have 24V DC potential for short circuit.
