RECOMMENDED WIRING SCHEMES
4.1
Typical wiring diagram
Control voltage and discrete input voltage from
different sources.
Control voltage and discrete input voltage from the
same source.
Notes:
(1) - Use fuses for type 2 coordination. Refer to section
4.2.1 on page 10
(2) - Solstart Plus incorporates a universal power supply unit for DC and AC control voltage: 110-
230V 50/60Hz or 110-230VDC.
(3) – Discrete input voltage can be either 110-230V 50/60Hz or 110-230VDC.
This voltage can be from a different voltage system then the control voltage or of the same
system.
(4) – End Of Acceleration contact (EOA) exist in models Solstart Plus
58 and up.
(5) – Fault contact closes in fault conditions.
(6) - When emergency stop switch is required it is recommended to trip a series contactor or the
feeding circuit breaker. (Not shown)

Wiring Notes
When mains voltage is connected to the Solstart Plus, even if control voltage is
disconnected, full voltage may appear on the starter load terminals.
Therefore, for isolation purposes, it is necessary to connect an isolating device
before the starter.
Power factor correction capacitors must not be installed on starters load side.
When required, install capacitors on starter’s line side.
WARNINGS!
Never connect the Solstart Plus “Inside Delta”!
