GND, GND1 and GND2 must all be commoned. See
section 9.2.
Ensure that the wire gauge used for these connections is appropriate for the
current to be drawn. Ideally, wires should be double crimped or independently
secured to ensure they cannot come loose. Route low voltage and mains wiring
separately. If they must be loomed together ensure that low voltage insulation
rating is sufficient or that supplementary insulation is used.

PP610F and PP612F Serial Connector
The RS232 connector is a standard 9-way female D-type connected as follows.
A standard straight through cable can be used to connect the PP600 to a PC
serial port.

PP602F and PP612F CCS Connector
Refer to section 12 for details on connecting to CCS lighting.

Power Supply
The PP600 has split power input connectors for the control circuit and the two
output channels. This is so that crosstalk between the outputs can be minimised
when one channel has a high output current.
Start by wiring the PP600 up as in section 9.2.1. It is possible to run the two
channels and digital system from two or three separate supplies as shown in
9.2.2, though this will rarely be necessary.
Power supplies should be regulated with SELV compliant outputs (fault
tolerant). Consideration should be given to fusing VS1+ and VS2+. The fuse
value can be based on the average current output. Note that in Europe fuses are
designed to pass at their rated current, while in the USA fuses are designed to
blow at their rated current.
