which disconnects all poles must be fitted wiin 2m and in sight of machine.†
All units must be correctly eared/grounded. An ear leakage trip of e
current operating type (30mA) is recommended to be fitted to is heat pump
and any associated equipment. When fitting recommended ear leakage trip,
to avoid nuisance tripping, e machine should be connected to its own 30mA
trip separate from any oer associated equipment.

nominal voltage. (415V for 3~N 50Hz) . The lamp on e phase rotation
relay, situated in e electric box, is illuminated when e phases are
correctly connected and e voltage is sucient.
Minimum Maximum
Voltage
Single phase machines 207V 253V
Three-phase machines 360V 440V
Cycle frequency 47.5Hz 52.5Hz
N.B. This voltage must be available at e heat pump whilst running.
† Note e isolator must have a minimum of 3mm air gap when turned off.
