Power Wiring
The Zener Smartstart
®
6000 is installed between the
mains and cable to the motor. If a mains or isolation
contactor is used it is best controlled by the starters
‘Line relay’.
3Wire or 6wire: The standard connection of an
electronic soft starter to a motor is 3 wire.
An alternative connection is 6 wire or inside delta
connection. This is commonly used when replacing a
star/delta type motor starter.
Bypass / Continuous: The Smartstart
®
6000 can
operate with or without a bypass contactor. Some
models include an integral bypass contactor. The
bypass contactor reduces the heat dissipation of the
soft starter as the semiconductors are bypassed after
the ramp time.
Select cables & install in compliance with
local regulations
Motor Protection:
The Smartstart
®
6000 provides advanced motor
protection with user selectable overload classes, over
& under current protection, phase imbalance and
thermistor protection. It is important that the power
wiring is followed correctly to ensure proper
protection and starter performance.
Refer to page 23 ‐ 26 and 39 for more details regarding
motor protection.
Semiconductor Fuses
Semiconductor fuses are recommended for all
electronic soft starters to provide protection of the
thyristors in the event of an output short circuit.
Semiconductor fuses are strongly recommended for
applications such as submersible pumps.
Semiconductor fuses are optional with all models.

For smaller models (15 – 80Amp) fuse kits are
available.

For larger models semiconductor fuse kits are
available which mount to the ‘Line’ Busbar.

conductor fuses.
