For instructions on grounding the switch and connecting it to power, see the Connecting to Power, on page

Wiring the External Alarms
Use M12 A-coded cable to connect to the alarm connector on the switch. Recommended torque is 4.43 to
7.08 in/lbs (0.5 to 0.8 Nm).
The recommended cable part number from Molex is 1200650523. One end of the cable has M12 A-coded
connector and the other end is open.
The labels for the alarm connector are on the switch panel and are displayed in the following table.
Table 7: Alarm Connector Labels (Top to Bottom)
Connection Label Pin
Alarm Output Normally Open (NO) connection NO 1
Alarm Output Normally Closed (NC) connection NC 2
Unused UNCONNECTED 3
Unused UNCONNECTED 4
Alarm Common connection COMMON 5
The input voltage source of the alarm output relay circuit must be an isolated source and limited to less than
or equal to 24 VDC, 1.0 A or 48 VDC, 0.5 A.
Caution
Connecting Destination Ports
These section provides information about connecting to the destination ports.
IP66/IP67 UL50E Type 4X compliant only when all cables are mated and torqued appropriately or with the
supplied dust caps attached. Caution
Connecting to 10/100 and 10/100/1000 Ports
The 10/100 and 10/100/1000 ports automatically configure themselves to operate at the speed of attached
devices. If the attached ports do not support autonegotiation, you can explicitly set the speed and duplex
parameters. Connecting devices that do not autonegotiate or that have their speed and duplex parameters
manually set can reduce performance or result in no linkage.
To maximize performance, choose one of these methods for configuring the Ethernet ports:
• Let the ports autonegotiate both speed and duplex.
• Set the port speed and duplex parameters on both ends of the connection.
