Electrical System Overview
The WHE-3 electrical system comprises a 380 or 440 VAC power circuit and a 24 VDC
control circuit. The power circuit is the electrical supply for the heaters, pump motor and DC
power supply unit. The control circuit provides power supply to all control, indication and
safety circuits.
HIGH VOLTAGE – HIGH CURRENT
THIS IS A HIGH VOLTAGE / HIGH CURRENT SYSTEM AND ONLY TRAINED,
COMPETENT PERSONNEL SHOULD ATTEND TO INSTALLATION, SERVICE AND
MAINTENANCE REQUIREMENTS. ALL RELEVANT SAFETY PROCEDURES MUST BE
FOLLOWED.
The remote control panel requires cable connection to the WHE-3 unit and these connections
are detailed in the electrical drawings provided in Appendix C.
The WHE-3 main panel and remote control panel are operated with a 24 VDC control system.
Ideally this should be supplied directly from the WHE-3 unit, however it may utilize an
independent supply if required. Terminals are provided on the remote panel and in the
WHE-3 main panel to facilitate installation and faultfinding.
