4.1 Installation site checklist
DANGER:
Never install the system controller in an explosive or flammable environment.
WARNING:
• Always refer to the local and national regulations, legislation, and codes in force
regarding selection of installation site, and water and power connections.
• Keep the manual, drawings, and diagrams accessible for detailed installation and
operation instructions. It is important that the manual is available for equipment
operators.
• Install the unit on the motor fan cover. Keep motor cables as short as possible. Check
the motor characteristics for actual tolerances.
• For wall mounting installations with long motor cables, use the output filter option to
protect the motor.
• Ensure that the ingress protection rating of Hydrovar (IP55, Type1) is suitable for the
installation environment.
CAUTION:
• Ingress protection. IP55 (Type 1) rating can only be guaranteed if the unit is properly
closed.
• Make sure that there is no liquid on the unit before opening the plastic cover.
• Ensure all cable glands and unused holes for glands are properly sealed.
• Ensure that the plastic cover is properly closed.
• Device damage through contamination. Do not leave Hydrovar uncovered.
4.2 Frequency converter and motor pre-installation check list
• Compare the model number of the unit on the nameplate to what was ordered to
verify the proper equipment.
• Ensure each of the following are rated for same voltage:
– Mains (power)
– Frequency converter
– Motor
• Ensure that the frequency converter output current rating is equal to or greater than
motor service factor current for peak motor performance.
– Motor size and frequency converter power must match for proper overload
protection.
– If frequency converter rating is less than motor, full motor output cannot be
achieved.
