If a custom power supply is used, use the power cable with pig tail ends. Connect the female end of the circular
mini-change cable to the power connector on the switch (torque = 10in/lbs) and connect the pigtail to the
non-standard power supply.
This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the
protective device is rated not greater than: 10 A Statement 1005
Warning
The recommended torque to achieve IP67 compliance is 10 in-lbs (1.13 Nm) for the power input connector
on the switch, power output and input connector on the Cisco IP67 power supply.
Grounding the Switch
Follow any grounding requirements at your site.
This equipment is intended to be grounded to comply with emission and immunity requirements. Ensure that
the switch functional ground lug is connected to earth ground during normal use. Statement 1064
Danger
To make sure that the equipment is reliably connected to earth ground, follow the grounding procedure
instructions, and use a UL-listed ring terminal lug suitable for number 10AWG wire (Hollingsworth part
number R3456B or equivalent).
Caution
Use at least a 4 mm 2 conductor to connect to the external grounding screw.
Caution
A ground lug is not supplied with the switch. You can select from these options:
• Single ring terminal
• Two single ring terminals
To ground the switch to earth ground by using the ground screw, follow these steps:
Procedure
Step 1
Use a standard Phillips screwdriver or a ratcheting torque screwdriver with a Phillips head to remove the
ground screw from the switch. Store the ground screw for later use.
Step 2
Use the manufacturer guidelines to determine the wire length to be stripped.
Step 3
Insert the ground wire into the ring terminal lug, and using a crimping tool, crimp the terminal to the wire.
See the following figure. If two ring terminals are being used, repeat this action for a second ring terminal.
