LEESON SM Series Sub-Micro Inverters - Manual (Page 15)

8.1 INPUT AND OUTPUT WIRING
On single phase input models, wire the input power to terminals L1 and L2/N. On three phase input
models, wire the input power to terminals L1, L2, and L3. Refer to Section 9.0 - SM Series
™ POWER
WIRING DIAGRAM.
All three power output wires, from terminals U, V, and W to the motor, must be kept tightly bundled
and run in a separate conduit away from all other power and control wiring.
It is not recommended to install contactors or disconnect switches between the drive and motor.
Operating such devices while the drive is running can potentially cause damage to the drive’s power
components. If such a device is required, it should only be operated when the drive is in a STOP state.
If there is potential for the device to be opened while the drive is running, the drive must be programmed
for COAST to stop (see Parameter 4 - STOP METHOD), and an auxiliary contact on the device must
be interlocked with the drive’s run circuit. This will give the drive a stop command at the same time the
device opens, and will not allow the drive to start again until the device is closed.
