5.3 Front & Rear Panel Marking
5.3.1 Power input port
The Model LI-220C has a IEC C20 receptacle for connection to an external
DC or AC input power source.
CAUTION
Due to the high level of earth leakage current, the device cannot be
connected to any power source protected by either a g
round fault circuit
interrupter (GFCI) circuit breaker
or residual current devices (RCDs).
The power source must be protected by a circuit breaker with a current
rating which is greater than or equal to the rating of the LISN.
5.3.2 Grounding bolt (GND)
The threaded bolt with hex nut marked 'GND' are found on rear panel of
the LISN. This bolt is used for Protective grounding connections. In addition
to this, the un-painted bottom surface of the LISN should be bonded
directly to an earth referenced ground plane for effective RF reference
ground. In cases where no ground plane is available, a mains isolating
transformer shall be used.
