Power Supply - Important Safety Information

The Model 340 Power Supply must be wall-mounted on to plasterboard, wood

or a similar non-conductive material, in a protected indoor environment and

close to a 240V AC electrical supply eg. an electrical cupboard. Connections to

the 240V AC mains supply must be carried out by a qualified electrician or similar

competent person, and made in accordance with accepted safety practices.

A two-pole switch ( as provided by a Consumer Unit or Switch-Fuse) must be

included to isolate both Live and Neutral during Installation or Maintenance. The

circuit must be protected by a fuse or other current-limiting device, rated

according to the capacity of the cable used, up to a maximum of 10A.

Fuse

The transformer is protected by a fuse; always replace this with the correct type

and rating:

T200mA 250V (20mm glass fuse, 200mA, 250V, Time delay, approved to BS

EN 60127 or equivalent)
