Warnings – read before installation or use
Do not apply AC mains power until all the preliminary
activities and interconnections have been completed.
AC voltages in excess of 100 volts can be dangerous
and even lethal under certain conditions. To prevent
injury to personnel and damage to the controller,
ensure that it is disconnected from the AC power
source (not just switched off) before any dismantling
takes place.
Only suitably qualified engineers should carry out
maintenance.
Ensure that the power earth connection is correctly
made.
Always check that the supply voltage specified
is correct for the local AC power supply voltage.
The controller consists of electronic parts. Do not
drop the controller or bump it against other objects
or place the controller near heat sources such as
radiators or air conditioning ducts.
Care should be taken so that solid objects or liquid do
not fall into the Controller enclosure.
Clean the case with a soft dry lint free cloth, or a soft
cloth lightly moistened with a mild detergent solution.
Do not use any type of solvent such as alcohol, which
might damage the special ‘Nextel’ finish.
