Safety Information and Declarations
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:

Model 840 Power Supply (with battery standby)
The Model 840 power supply 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.
