Precautions
When undertaking electrical installations, please note the following:
All mains voltage electrical work must be carried out by a qualified
electrician, especially external power outlet socket installation.
A readily accessible disconnect device, over current device and RCD
Protection rated to suit the size of the pump plus 5VA must be incorporated
in the power supply wiring. The over current device for a 1500W, 240Vac
pump must not exceed 10Amps.
Sensor leads should be kept 300mm (12 inches) away from mains and
comms cables.
Do not use mains power extension cords unless approved by the
manufacturer. Water resistant plugs and sockets should be used.
The SolaSmart™ controlled output (PUMP) will be connected to the input
power supply wiring and is not isolated from it. Supply voltages will be output
through that outlet during activation.
The HWC outlets are isolated contacts. A supply wire and an output wire will
need to be wired to each HWC outlet.
Always use the unit within specified voltage and load ranges. Never use with
damaged leads, plugs or sockets.
Do not allow the sensor cable to come within 10mm of the high voltage
connectors or components inside the enclosure.
The electric element should have a fuse that is rated within the stated
maximum of the relay driving the element.
Do not connect the mains or the pump to a circuit that could be switched off
by your electricity supplier to manage peak loads (ripple control).
Comply with all local and relevant electrical regulations.
Warning
These products are not designed for use in, and should not be used for,
applications which are in conjunction with items that are critical to any
person’s health (e.g. life support systems).
In any critical installation, an independent fail-safe back-up system must
always be implemented.
