The DLCM with an attached pump motor and alarm load, should be connected to its own branch
circuit. Size the supply wire and protective element according to local code requirements. Use 14
AWG, 105
° C insulation wire or better. Attach the supply to the J1 terminal block labeled 'LINE
POWER IN'. Make 3 connections: Neutral, Earth (ground) and Hot as labeled.

* In-rush current requirements should be considered. All values RMS.
** Calculation is for guideline purposes only. User must consult local electrical codes when sizing branch
circuits. Protection must not exceed 10Amps RMS at 115VAC or 5.5Amps RMS at 230VAC.

The operating voltage and frequency of the DLCM are factory configured – an internal motor and
capacitor are sized according to voltage and frequency. If the power supplied to the unit does not
match the factory configuration, the DLCM will display either an {OVER VOLTAGE} or {UNDER
VOLTAGE} diagnostic message on power-up. This is possible because the microprocessor and
display are powered by a switching power supply. It detects the incoming power and self-regulates its
output. This power supply is protected by a 7.4 Joule surge suppression device. The microprocessor
will not operate the internal stroke adjustment motor, potentially causing damage, until the voltage
problem is corrected.
