ELECTRICAL INSTALLATION
All electrical work associated with the E30
must be carried out by qualifi ed electrical
personnel and all electrical work must
conform to AS/NZ standards and to local
wiring rules.
INTRODUCTION
When used with its HD terminal link in place the E30 can directly control
single-phase motors to 2.4kW via its Relay 1. No interposing contactor is
required for such applications. The E30 can also be used to control 3 phase
motors of any size via an appropriate interposing contactor.
WARNING: The contactor control circuit must never exceed 240VAC.
Never series connect the E30 relay contacts and contactor coil directly
across 2 phases.
The E30 requires a stable 220V to 240V AC 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 (FELV) and neutral terminal N
(see the included wiring diagrams). When operated from a low voltage DC
supply the terminals LV (FELV) and neutral N are not polarity sensitive.
Pay attention to cable sizes and ensure cables are adequate for the specifi c
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 E30 may repeatedly reset and not
operate properly.
