The unit has a Technical Earth terminal (marked ) located at the rear
panel (See Figure 2.3). Its use is recommended. This is NOT a Protective
Earth for electric shock protection. The terminal is provided to:
1. Ensure all equipment chassis fixed within a rack are at the same
technical earth potential. To do this, connect a wire between the
Technical Earth terminal and a suitable point on the rack.
2. Eliminate the migration of stray charges when connecting between
equipment.

Connecting the Equipment to the AC Power Supply
As there is no mains switch fitted to this unit, ensure the local ac power
supply is switched OFF before connecting the supply cord.
Connect the supply cord to the Modulator and then to the local supply.
