WARNING: DO NOT CONNECT POWER SUPPLY WITH MORE
THAN 15Vdc VOLTAGE.
Important notes:
In general, "D" Connector numbering patterns are standardized. There are,
however, some connectors with nonconforming patterns and the
numbering sequence on your mating connector may or may not coincide
with the numbering sequence shown in our pin configuration table above. It
is imperative that you match the appropriate wires in accordance with the
correct sequence regardless of the particular numbers displayed on your
mating connector.
Make sure power is OFF when connecting or disconnecting any cables in
the system.
