The electrical control panel is situated within the cabinet and has front access for essential maintenance of the unit. This
contains major components such as:
•
Mains isolator
•
Circuit breakers/ fuses for protection of major unit components
•
Power monitoring (based on unit selection)
•
24V transformer and controllers
•
Mains and inter-connecting terminals (this includes volt-free contacts for common alarm).
The panel is wired to the latest standards and codes of practice for the relevant market.
The SmartCool One is available in the following supply voltage options:
•
400V / 3Ph + N / 50Hz (-0) -
Three phase and neutral star connection electrical supply configuration at 50Hz
frequency. Nominal L-L voltage is 400V and nominal L-N voltage is 230V.
•
460V / 3Ph / 60Hz (-3) -
Three phase delta connection electrical supply at 60Hz. Nominal L-L voltage is 480V and
utilisation L-L voltage is 460V.
•
380V / 3Ph + N / 50Hz (-A) -
Three phase and neutral star connection electrical supply configuration at 50Hz
frequency. Nominal L-L voltage is 380V and nominal L-N voltage is 220V.
Single Power Supply
Single power supply is a standard feature on the SmartCool One. -0 and -A supply voltage units have a door interlocked
mains isolator as standard. Door interlocked mains isolator is an optional feature for -3 supply voltage units.

Dual Power Supply (ATS)
Dual power supply automatic transfer switch (ATS) is designed for use in power systems to safely transfer a load supply
automatically between a normal and alternate source. In the event of a power failure, the supply can be switched from
utility to an alternative power supply (such as second utility or generator). For the automatic transfer feature to operate
effectively, the two incoming power supplies must have the same voltage and frequency. During changeover of power
there is a short break of power and the Ultracap backup module is used to maintain power to the unit controls, allowing
for immediate reinstatement of cooling following changeover.
The automatic transfer switch offers switch position status and supply priority set, both of which are configurable via the
unit’s display, and is used to set which of the two power supplies power will be drawn from when both power supplies
are active. Switch position status indicates to the end user which position the switch is currently in, i.e. A or B and is
shown via the unit’s display. When the automatic transfer switch option is fitted, the Ultracap backup is fitted as standard
to reduce unit downtime and keep loss of cooling to a minimum.
