Connecting Ground Cable
The protective earth connection to the SMG-3200 is provided via three core mains lead. The earth
wire in the mains cord (Green/Yellow) is connected in the factory to the earth terminal within the
system. The Earth wire is connected directly to the ground connection on the rear panel of the
system.
The protective earth (PE) is used for surge protection and for the electrical safety of the system.
The system must be plugged into a GPO socket that is correctly earthed. The PE provided all
system earthing requirements, a TRC is not required and should not be connected.
Before connecting ground cable, ensure that AC power supply cable is
disconnected. With power cable connected, connecting ground cable may
cause damage or possibly death.
