Pulser Wiring Notes
Notes: 1) All the pulsers shown above are connected to Hose 1.
2) Jumpers on the Pump Control PCB must be properly jumpered according to the
pulser type. This should be done by the person performing the start-up. Power to the
system must not be turned on prior to this setup.

4) When installed in a separate DC conduit, 18 AWG wires are required for
installation. Although it is recommended that DC pulser wires be run in a separate
conduit away from AC wires, they can be combined in the same conduit with AC
wires providing UL-listed cable with the following specifications is used:
• Conductor: 18 AWG stranded wire. Number of conductors to be determined by
pulser
• Shield: Foil-wrapped 100% coverage and/or tinned copper braid 90% coverage
• Drain Wire: Stranded, tinned copper, 20 AWG or larger/or braided shield
• Voltage Rating: Maximum operating voltage of 600 V
