START GUIDE
Start Guide for FM50 series Inverters
& motors
This guide is to assist you in installing/ running the inverter and
verify that it is functioning correctly for the main and basic features
of Inverter.
For detailed information and if there are any doubts please refer to
the instruction manual.
Supply & Motor connection
1) Ensure that the Inverter & the motor have the correct
KW power and voltage ratings.
Motor full load amps must not exceed the Inverter rating.
2) Ensure that the Supply & Motor cables are connected
correctly prior to switch on.
3) For single phase supply, use L1(L) & L3(N) on units
which has 3 supply terminals.
On units with two supply terminals L1&L2, connect the
live to L1 and the Neutral to L2.
4) Connect motor cable to terminals T1, T2 & T3.
(Swap any two leads if motor runs in reverse direction).
5) Connect both supply & motor Earth to the drive Earth
terminal tag strips, screw this to the bottom left case
screw.

Remote speed reference and Remote run
Wiring for Remote mode
1) Ensure that you have carried out installation & wiring
requirements as per step1 quick start guide on previous
page before you proceed.
2) Check the position of SW1. Down position for 0-10Vdc.

Our all ranges of INVERTERS are
designed as a motor control and you
should always connect the output direct
to a motor.
Do use a fixed connection to the AC power line.
DO put a three phase motor directly on the U, V, W or T1, T2,
T3 terminals.
DO wire all switching and control to the input side of the
inverter.

Running Three Phase Motors from
"Single Phase 240V" Inverters.
If your motor was originally wired to an industrial three phase supply, it
is likely that the motor voltage is wired for 415V. The inverter will run
the motor without harm, but the torque will be a fraction of what it
should be.
Here's how to check, and if necessary change the motor wiring.
On the left is a typical TECO MAX-E2 motor
rating plate. In the 50Hz box of data you will
see a voltage rating "220-240V / 380-415V
". This information tells us that the motor can
be wired for two voltage ranges.
In the or Delta configuration, the motor will
run on a three phase supply from 220V to 240V
phase to phase.
In the or Star configuration, the motor will
run on a three phase supply from 380V to 415V
phase to phase.
How to determine the motor configuration?
Connection
On the left is a typical TECO & MONARCH motor terminal arrangement.
The drawing shows the Star configuration. The three wires from the
Inverter output terminals directly to the U1, V1 and W1 leads. The other
three leads W2, U2 and V2 are linked together often with a set of brass
stampings or strips. Wires are also used to make the circuit. For small
motor (*Notes) this star connection would be consistent with 415V
operation.
*Notes: The TECO small motor is 4Kw & below.
The MONARCH small motor is 3Kw & below.
The motor terminals shown on the right are wired in a Delta configuration.
The brass strips, used to make the star connection above, are simply
removed and rearranged.
To find out a spare strip to make the third connection.
Wires the inverter go directly to the U1, V1 and W1 leads as usual. In the
Delta case the connections will share the terminal U1 and W2, V1 and U2,
W1 and V2 with the brass strip. The small motor is now wired for 240V
operation.
