Step 1 - Installation
• Controller enclosure must be mounted in a vertical position.
• Ensure mounting method does not compromise enclosure weatherproof rating.
• Ensure access to main isolator is not restricted.
• Ensure cables/conduits entering the panel have mechanical protection and that the penetrations are sealed and do not
compromise the weatherproof rating of the enclosure.
Warning: All electrical connections must be carried out by a suitably
qualified and registered electrician

Step 2 - Connections
Follow the relevant controller’s Inner Door Label on the inside of the enclosure door for power, pump and sensor connections to the
din rail mount terminals.
Step 4 - Powerup
When safe to do so, switch on electrical supply to panel. Check correct supply voltage before turning on the main isolator.
Harmonic Consideration
With all variable speed drives there will be some harmonic distortion on the main power supply. The drives used in the HydroWHIZ VSD
have internal filters to reduce the amount of distortion, however in some applications additional filtering may be required. If additional
harmonic filtering is required to meet site specifications this can be requested. See below an excerpt from the Australian Standard AS/
NZS 61000.3.6 “Limits - Assessment of emission limits for distorting loads in MV and HV power systems”:
‘Power utility companies and Australian Standards stipulate maximum harmonic levels which apply at a customer’s PCC (point
of common coupling). Generally, the maximum permissible harmonic levels are given in terms of % THVD however to achieve a
reduction in THVD, the customer is required to reduce their THID through the use of harmonic mitigation equipment. Commonly, THVD
levels are required to be between 5-8%, however this will vary from state to state. IEEE STD 519 (1992) and AS/NZS 61000.3.6 (2001) are
two widely used harmonic limit standards, however other standards may also be relevant including AS/NZS 61000.3.2 2007. Please
confirm harmonic requirements with your utility provider. For more information please refer to the relevant standard.’
Step 3 - Adjust Fan Thermostat
Adjust the thermostat that controls the cabinet fan to a temperature suitable for the ambient temperature
and environment the controller is installed in. A recommended setting would be around 25-30°C.
