ELECTRIC SCHOCK CAN KILL! Precautionary measures should be taken to provide maximum
protection against electrical shock.
Be sure that all power is OFF by opening the line (wall) disconnect switch when primary
electrical connections are made to the power source.
Be sure to check your input leads with a voltmeter to make sure all power is OFF.

Terminating resistor
In order to avoid communication interference, the ends of
the CAN bus must be fitted with terminating resistors.
One end of the CAN bus is at the control panel, which has
an integral terminating resistor. The other end at the
power source must be fitted with the terminating resistor,
as shown on the right.

Check that the unit is connected to the correct mains power supply
voltage, and that it is protected by the correct fuse sizes. A
protective earth connection must be made, in accordance with
regulations.
