ST.RE.TT1222.2

NOTE…
There is no user-replaceable fuse in the rear of the unit.

2.5.2 Technical

Earth

The Technical Earth provides a suitable connection between the TT1222

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

frequencies. A terminal at the rear panel (left of the power socket) 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.

Figure 2.2: Technical Earth Connector

NOTE…
The technical earth shall be fitted with a bolt of M4 x 6 dimensions, 4 millimetres in diameter, and no

longer than 6 millimetres.

CAUTION…

It is strongly recommended that the Technical Earth terminal at the rear panel of the equipment be

connected to a site Technical Earth before any external connections are made and the equipment is

powered. This limits the migration of stray charges.

2.5.3

AC Power Supply Cord

General

A mains cord is normally supplied with this product. It is fitted with a

moulded plug suitable either for mainland Europe, the UK, Australia or

USA as advised when ordered.

NOTE…
The TT1222 is not fitted with an ac power supply ON/OFF switch. Ensure the socket-outlet supplying

the equipment is installed near the equipment, so that it is easily accessible.

When replacing the power cord in the USA, make sure to always replace it

with a cord of the same type. The cord should be of type: Feller type SVT

cord rated 3x18 AWG with plug 498 G and appliance coupler C13.
