Installation
■ Wiring
1. Power lead polarity
The red power lead leading from the pump is positive polarity
and must be connected to a positive contact of a DC power
supply, and the black power/signal lead leading from the pump
is negative polarity and must be connected to a negative con-
tact of the power supply.
2. 1-5V control signal polarity
The white signal lead leading from the pump is positive polarity
and must be connected to a positive contact of a 1-5VDC sig-
nal generator, and the black power/signal lead leading from the
pump is negative polarity and must be connected to a negative
contact of the signal generator.
NOTE: The black power and signal leads are leading from the
common negative terminal of the pump.
3. Pump speed signal polarity
The green signal lead leading from the pump is positive polar-
ity and must be connected to a positive polarity of the counter.
4. Wiring diagram
Optimal diagram changes depending on if the 1-5VDC control
signal is used or not.
5. External fuse
Install an external fuse in the power line for overcurrent protec-
tion.
