5.5.1 Supply Power
The DLC-RC requires one connection to an external power source. It uses this same connection to
power its own supply, the motor starter relay (external) and the alarm relay output. The user must
be mindful of these external loads when sizing the branch circuit.
The DLC-RC power supply and attached PULSAR motor starter relay (external) are not fuse
protected. The user is responsible for correctly sizing the protection element (i.e., fuse or circuit
breaker at the distribution panel). Use the work sheet in Table 2 for correctly sizing the branch
protection element.

Device Current Requirement(Amp) Device Current Requirement (Amp)
DLC-RC 1A (1A Max.) DLC-RC .5A (.5A Max.)
Motor Relay* + (8A Max.) Motor Relay* + (4A Max.)

Total DLC-XP** 1A (1A Max.) Total DLC-XP** .5A (.5A Max.)
* 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.
Table 2: Branch Circuit Protective Element Sizing Worksheet.
The DLC-RC with an attached pump motor relay 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.
The DLC-XP should also 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.
The operating voltage and frequency of the DLC-XP are factory configured -- an internal
motor/capacitor and power supply are sized according to voltage and frequency. Attempting to
operate DLC-XP outside of rating will result in damage to the unit that is not covered by the
warranty.
The operating voltage and frequency of the DLC-RC are also factory configured. If the power
supplied to the DLC-RC does not match the factory configuration, it will display an {OVER
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 DLC-XP, until the voltage problem is corrected.
High Voltage circuits (e.g., branch) should be run in separate conduit. Do not combine High
Voltage (i.e., greater than 100VAC) lines and Low Voltage (i.e., less than 28VDC) lines in a
common conduit!
5.5.2 PULSAR Motor Starter Relay (DLC-RC)
Connect the pump motor starter relay to the J3 terminal block on the DLC-RC labeled PUMP
'MOTOR OUT AC/DC.' Use 14 AWG, 105° C insulation wire size or larger. The pump motor
starter relay must be wired to operate at the DLC-RC supply voltage (i.e., if the power supplied to J1
is 115VAC 60Hz, then the motor must operate on 115VAC at 60Hz).
