DH+ Connection
To attach a personal computer to a ControlNet PLC-5 processor using
a DH+ connection:
When used in a Class I, Division 2, hazardous
location, this equipment must be mounted in a
suitable enclosure with proper wiring method that
complies with the governing electrical codes.
If you connect or disconnect the DH+ cable with
power applied to this processor or the device on the
other end of the cable, an electrical arc can occur.
This could cause an explosion in hazardous location
installations. Be sure that power is removed or the
area is nonhazardous before proceeding.
