A means for disconnection of the IPG20 must be incorporated in the fixed
wiring in accordance with the wiring rules.
The IPG20 requires a stable 110V to 240V 50/60Hz supply when operated
from the mains. It can also be operated from an 18 to 24V AC or DC supply
by utilising the low voltage active terminal LV and neutral terminal N (see the
included wiring diagrams). When operated from a low voltage DC supply
the terminals LV and neutral N are not polarity sensitive. Pay attention to
cable sizes and ensure cables are adequate for the specific pump motor
load. This is particularly important where long cable runs are to be used in
the installation. If the voltage drop associated with the starting of the pump
motor is excessive the IPG20 may repeatedly reset and not operate properly.
The IPG20 is designed to directly control single-phase pump motors to
2.4kW via its Relay 1. No interposing contactor is required for such
applications. The controller can also be used to control 3 phase pump
motors of any size via an appropriate interposing contactor.
WARNING:
The contactor control circuit must never exceed 240VAC.
Never connect the IPG20 and contactor coil directly across 2 phases.
