Electrical Details
Isolation - Before commencing work make sure
that the unit, switched live and Nuaire control are
electrically isolated from the mains supply.
Warning - Inverter Speed Control
An Inverter is used to provide speed control. When the fan is
isolated, allow 5 minutes for the capacitors in the inverter
to discharge before commencing any work on the unit.
RDC
If a RDC is fitted to protect the circuit, a type B RCD should
be used (trip limit 300mA). Otherwise nuisance tripping will
occur.
Because the run and start currents depend upon the duty
and associated ductwork of an individual unit, the values
quoted in the table are nominal.
Run currents will be exceeded if the unit is operated with its
cover removed. It is therefore recommended that the unit is
not run for prolonged periods in this condition.
