Connecting the Equipment to the AC Power Supply

As there is no mains power switch fitted to this unit, ensure the local ac

power supply is switched OFF before connecting the supply cord.
Connect the mains lead to the TT1260 and then to the local supply.

2.6

Technical Earth Connection

The terminal marked at the rear panel is a Technical Earth. It 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.

The Technical Earth provides a suitable connection between the TT1260

and the installation to give a low impedance path at normal operating

frequencies.
