Grounding the Chassis
The ION002-AD chassis comes equipped with grounding lugs located on its back panel. They require a grounding
conductor wire terminated with a two-hole, compression-type, grounding connector (not provided). The grounding
wire (must be a copper conductor) is not included with the chassis and must be provided by the
customer/installer.
The electrical-conducting path from the ION002-AD chassis must:
•
Flow via the grounding lugs to the common bonding network (CBN) for telecom installations, or to an
alternative approved grounding system (if required) for non-telecom installations.
•
Be of sufficiently low impedance to conduct fault currents likely to be imposed on the media converter.
•
Enable proper operation of any over-current protection devices.
Grounding Wire Size
The wire size of the Protective Earth (ground) conductor should be greater than or equal to the wire size of the
power source conductors. The power-source conductor wire size is installation dependent and sized to
accommodate acceptable IR losses between the power source and the device terminal block. The device terminal
block accommodates #6 wire lugs. A #6 wire lug typically terminates #16 - #20 wire; with #18 most common.
Connecting the Ground Wire
The conductor must be fastened to the grounding lugs with the enclosed antirotation star-washers and lug-nut
fasteners. The torque requirement for the connector lug-nut fasteners is specified by the connector’s
manufacturer.
Grounding Methods
The conductor must be fastened to the grounding lugs with the enclosed antirotation star-washers and lug-nut
fasteners. The torque requirement for the connector lug-nut fasteners is specified by the connector’s
manufacturer.
To properly ground the ION002-AD chassis:
1. Obtain one (1) a two-hole, compression-type, grounding connector.
2. Attach the grounding conductor to the chassis by placing the two-hole connector onto the grounding lugs and
fasten with the enclosed lockwashers/lug-nuts at the proper torque (per the manufacturer’s specification).
3. Attach the opposite end of the grounding conductor to the common-bonding network (CBN) for telecom, or to
earth ground (if required) for non-telecom installations.
