Connecting the PP8xx
Refer to
Section 11, PP8xx reference information
for the ratings of the
connections. To prevent overload of output wiring, all power and output
cabling must be rated for a continuous load current of 6.3A minimum.
However, this does not apply to the Ethernet, RS232 and trigger input
connections.
The PP8xx's connections are shown below:
7.1
Power
Any power supply derived from mains electricity must have a Safety Extra
Low Voltage (SELV) output. Route low voltage wiring to the PP8xx
controller separately from mains electricity wiring.
Please refer to
Section
2, Safety
.
If this is not possible, make sure the low voltage wiring has an insulation
rating that is appropriate or supplementary insulation is used. The
connections are shown below:
Note:
The case of the PP8xx is not connected to GND.
