Electrical Installation for the PM-600
From the mains electrical connection, install a permanent 230 to 250 volt, 50 Hz external
GPO in a suitable position near the pump module. The pump module draws a maximum
50 watts at full load.
The temperature sensors should not be in direct contact with fluid. Always use immersion
sleeves. Take the collector temperature sensor cable assembly and attach to the panel-
mounted, 2 way connector. This plug will only fit one way. The tank temperature sensor
cable is hard wired to the module, and exits the case through an M12 cable gland.
Should extra cable length be required, there is slack inside the module. Remove the
cover, loosen the cable gland, and pull through extra cord as required. Re-tighten cable
gland and replace cover.
