Important Safety Information

Connections to the 240VAC mains supply must be carried out by a qualified

electrician or similar competent person, and made in accordance with current

legislative requirements. 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. Use only

mains cable to BS6004 or equivalent, within the following specified limits:

Min Max

Conductor Diameter

1.0mm (0.8mm

)

2.25mm (4mm

)

Cable Diameter 4.0mm 8.0mm

Model 840 PSU (with battery standby)

The Model 840 PSU must be placed in a protected indoor environment such as an

electrical cupboard. It must be secured to the wall with adequate fixings so that there

is no possibility of it falling. The Lead-Acid Battery for the Standby Power Supply is

shipped in separate packaging. It should only be connected once the system has

been fully tested. Connection is made by 2 leads with spade terminals; observe the

correct polarity - red to positive, black to negative. Care must be taken to ensure that

the terminals of the battery are not shorted together by metal objects, as this may

constitute a Fire Hazard. The Control Cabinet is IP55 rated (to exclude dust) and is

vented to avoid the build-up of gases. Do not block any vents that may be apparent.

A good mains safety earth must be connected to the cabinet housing the power

supply

Where the power supply is fitted with a replaceable internal mains fuse and or battery

fuse, always replace with the same type as indicated on the power supply. The fuse

must be approved to BS EN 60127 or equivalent.

Model PS4 and 340C Power Supplies

These power supplies must be wall-mounted onto plasterboard, or a similar non-

conductive material, in a protected indoor environment such as an electrical

cupboard.

When fitting the power supply cable (both mains and low voltage) ensure the cable

entry cut-outs in the enclosure lid are no larger than necessary for the cable diameter

used and under no circumstances must they be taken beyond the outer cut-out

zones.

Videophone

The display module of the videophone has a high voltage circuit (2KV), which

represents a shock hazard. Do not remove the inner cover of the videophone

assembly, there are no user adjustments requiring this.
