Control Wiring
Connect “run” and “interlock” control wiring from the PowerFlex 700L
drive to the J1 connector on the control board. Refer to
terminal specifications.
Table 1.F Control Board Terminal Specifications
Run Wiring
The run output signal from the PowerFlex 700L drive must be connected to
the heat exchanger control board (
) so that the heat exchanger
automatically starts when the drive is started.
The heat exchanger J1 connector provides fault and alarm contact outputs to
monitor the operating state of the heat exchanger if desired.
