8.0 ELECTRICAL DETAILS
The electrical wiring must be carried out
by competent persons, in accordance with
good industry practice and should
conform to all governing and statutory
bodies i.e. IEE, CIBSE etc.
8.1 SUPPLY
ELECTRIC HEATER SUPPLY
The control is powered by a 400Vac 50Hz 3 phase & Neutral supply. This must
be isolated local to the unit and fitted with appropriate overcurrent and fault
protection.
For models with electric heating, the heating circuit is powered by 1 or 2
seperate, higher current, 400Vac 50Hz 3 phase & Neutral supplies. This must be
isolated to the unit and fitted with appropriate overcurrent protection. The main
supply is still required. Electric heater elements are protected by a fail-safe over-
temperature switch which will disconnect the heater supply if a temperature of
80°C is reached. Once the elements cool, the switch will reset but a power cycle
is required to reset the heater supply contactor.
* Denotes any character.
# These values do
NOT include the condenser units, which are powered by a seperate supply. See the table below or condenser manual.
† Single heater models require a seperate supply for the heater section, with an appropriate overcurrent current protection device.
‡ Double electric heater models require seperate supplies for two heater sections, each with an appropriate overcurrent current protection device.
