5.1 ELECTRICAL (MACHINE WIRING AND SUPPLY)
SEE FIG. 4,5, AND 6 FOR PREFERRED METHOD
The cable supplying electricity to a machine wi a given load must
increase in cross sectional area (C.S.A.) as e leng increases in order
at e voltage drop wiin e cable does not exceed recommended
limits. Cable sizing should be calculated by an appoved electrician. All
electrical work to be carried out in accordance wi I.E.E. standards,
latest issue, or local codes of practice as applicable.
The machine should be installed in accordance wi EMC2004/108/EC.
Protected supply to incorporate fuses or motor type circuit breakers
(Type C) to specified rating, (see Data Sheet). H.R.C. fuses are
recommended. An isolator 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.
Inconsistent electrical supply
The following limits of operation must not be exceeded if Danerm
Ltd. machines are to be guaranteed eier in performance or warranty

This voltage must be made available at e heat pump whilst running.
† Note e isolator must have a minimum of 3mm air gap when turned
off.
NOTE: All machines are fitted wi a phase protection relay and will not
run if e phases are not connected in correct order (phase sequence)
or if e supply voltage is 15% less an e nominal voltage. (415V for
3N~ 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. The undervoltage protection feature is not present
in phase protection relays fitted in 220V 3~ 60Hz machines.
