Safety Notes
Warning!
The mains (supply) voltage must be isolated before the mains (supply) connector is handled
.
Warning!
Any interruption of the protective conductor inside or outside the apparatus or disconnection of
the protective earth terminal is likely to make the apparatus dangerous under some fault
conditions. Intentional interruption is prohibited.
Note: In order to comply with the requirements of safety standard EN61010, the power supply
module must have one of the following as a disconnection device, fitted within easy reach of the
operator and labelled as a disconnection device.
i.
A switch or circuit breaker which complies with the requirements of IEC947-1 and IEC947-3
ii.
A separable coupler which can be disconnected without the use of a tool
iii.
A separable plug, without a locking device, to mate with a socket outlet in the building.
1.
Before any other connection is made, the protective earth terminal shall be connected to a protective
conductor.
2.
The Mains (supply voltage) wiring must be terminated in such a way that the Earth wire would be
the last wire to become disconnected should excess tension be applied to the mains cable.
3.
It is recommended that crimps be used to terminate the wires before they are inserted into the
terminal blocks.
4.
The Mains supply fuse within the Power supply unit is replaceable and should only be replaced with
a fuse of the same type and rating. In no conditions should the fuse be replaced with one of a higher
rating.
5.
Whenever it is likely that protection has been impaired, the unit shall be made inoperative and
secured against unintended operation. The nearest manufacturers service centre should be consulted
for advice.
6.
Any adjustment, maintenance or repair of the opened apparatus under voltage, is prohibited.
7.
The unit is designed for use only in an enclosure.
8.
Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning /
filtering / sealing etc. must be installed in the enclosure.
9.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by
the equipment might be impaired.
