CONDITIONS OF ACCEPTABILITY
In determining the acceptability of the combination, the following details should be
examined.
1. These devices should be mounted in an enclosure having adequate strength and
thickness. The front face of the touch screen controller may be used as part of an
enclosure.
2. These devices should be used within their recognized ratings as specified.
3. The terminals are suitable for factory wiring only.
4. The input circuitry of these devices have to be supplied from:
a) A Class 2 transformer in accordance with UL1585, or
b) an isolating device such that the maximum open circuit voltage potential
available to the circuit is not more than 28.8 Vac and the current is limited to a
value not exceeding 8 amperes measured after 1 minute of operation, or
c) a suitable isolating source with a maximum open circuit voltage potential of not
more than 28.8 Vac in conjunction with a fuse in accordance with UL248.
The fuse shall be rated max. 1.6 A and be installed in the input circuitry of the
device in order to limit the available current.
5. Spacing at factory wiring terminals of not less than 6.4mm (1/4 in) should be
maintained between any un-insulated live part and the walls of a metal enclosure.
