Connect the external power supply to the applicable input voltage source
and the output of the external power supply to the DC input connector on
the pump unit.
NOTE:
The Power Supply output connection is center positive (+).
Terminals 1 and 2 on the rear panel barrier terminal strip, Figure 1-3,
provide a means for connecting a remote DC power source. The positive
(+) terminal is terminal 1. The negative (–) terminal is terminal 2.
NOTE:
Input voltage must not exceed 15V DC or equipment may be
damaged. A minimum of 11V DC is required for proper operation.
Terminals 3 and 4 on the rear panel terminal strip, Figure 1-3, are used for
remote start/stop operation. Pump direction and speed are not remotely
controllable. In non-remote operation, these terminals are connected
together by a Shorting Bar.
For remote control by switch closure, remove the Shorting Bar and
connect the two terminals of the remote control switch to terminals 3
and 4. A closure of the remote control switch contacts will start the
Pump System. Opening the contact will stop the Pump System.
