Getting Started and Product Document of Compliance for the Cisco IR1101 Industrial Integrated Services Router

Grounding the Router

Make sure to follow any grounding requirements at your site. The ground lug is supplied with the device.
Warning: This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an
electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning: 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

For NEC-compliant grounding, use size 16 AWG (1.5 mm2) or larger copper wire and a ring terminal with an inner
diameter of 1/4 in. (6 to 7 mm).

For EN/IEC 60950-compliant grounding, use size 18 AWG (1 mm2) or larger copper wire.
Caution: Use at least a 2.3mm conductor to connect to the external grounding screw.
To ground the router to earth ground by using the ground screw, follow these steps:
1. Locate the ground lug in the packaging kit. Store the ground screw for later use.
2. Use a wire stripping tool to strip the 14-18 AWG (2.08-1.31mm²) grounding wire to 0.22 in. (5.56 mm).
3. Insert the ground wire into the ring terminal lug,
and using a crimping tool, crimp the terminal to the
wire.
4. Slide the ground screws through the ground lug.
5. Insert the ground screws into the two screw
positions (1) shown in the graphic.
6. Use a ratcheting torque screwdriver to tighten the ground screw and ring terminal to the router side
panel to a torque of 8 to 10 inch-pound (0.9 to 1.1 newton meter).
7. Attach the other end of the ground wire to a grounded bare metal surface, such as a ground bus, a
grounded DIN rail, or a grounded bare rack.
