SX80 and SX90 Quickstart Guide
Personnel
Installation must be carried out by suitably qualified personnel.
Enclosure of live parts
To prevent hands or metal tools touching parts that may be
electrically live, the controller must be installed in an enclosure.
Caution - Live sensors
The controller is designed to operate if the temperature sensor is
connected directly to an electrical heating element. However, you
must ensure that service personnel do not touch connections to
these inputs while they are live. With a sensor, all cables, connectors
and switches for connecting the sensor must be mains rated for use
in 240 Vac CAT II.
Wiring
It is important to connect the unit in accordance with the data within
this document ensuring that the protective earth connection is
ALWAYS fitted first and disconnected last. Wiring must comply with
all local wiring regulations, i.e. UK, the latest IEE wiring regulations,
(BS 7671), and USA, NEC Class 1 wiring methods.
Do not connect the ac supply to the low voltage
sensor input or low level inputs and outputs.
