overvoltage or other protection may be activated at power restoration according to the op-
erating condidition.
Temperature applicable for a short period in transit, etc.
The braking torque indicated is short-duration average torque (which varies with motor
loss) when the motor alone is decelerated from 50Hz in the shortest time and is not a con-
tinuous regenerative torque.When the motor is decelerated from the frequency higher than
the base frequency, the average deceleration torque will reduce. Since the inverters of the
FR-E500 EC Series does not contain a brake resistor, use the optional brake resistor when
regenerative energy is large. A brake unit BU may also be used.
Not valid for the inverters FR-E 520S-0.4 k, -0.75 k EC and FR-E 540-0.4 k, -0.75 k EC

4.2 Wiring of the Main Circuit
PDANGER:
The frequency inverter must always be powered off completely before performing
any wiring work. Before starting rewiring or other work after performing operation
once, check the voltage with a meter etc. more than 10 minutes after power-off.
For some time after power-off, there is a dangerous voltage in the capacitor.
ECAUTION:
The inverter must be grounded using the dedicated ground terminal.
Power must not be applied to the output terminals (U, V, W) of the inverter. Otherwise
the inverter will be damaged.
4.2.1 Mains, Motor and Ground Terminal Connections
The terminal blocks for connection of the frequency inverter can be accessed by removing the
front cover and the wire cover. Connect a 1-phase power supply to the terminals L1 and N when
using the inverter FR-S 520S EC/ECR and a 3-phase power supply to the terminals L1, L2 and
L3 when using the inverter FR-S 540 EC/ECR. The required power supply is 200–240V AC,
−15% / +10% for the inverter type FR-S 520S EC/ECR and 380–480V AC, −15% / +10% for the
inverter type FR-S 540 EC/ECR. The main frequency is 50–60Hz ± 5% for all types.
Connect the motor cables to terminals U, V and W. The illustration below shows the correct as-
signments for the power connections. Please see the main frequency inverter manual for details
on the required cable dimensions for your model.
NOTE The inverter must be grounded using the dedicated ground terminal.

4.3 Wiring of the Control Circuit
The following picture shows the arrangement of the terminal for the control circuit of the inverter:
*The control signal level can be adjusted with the jumper. At the factory the jumper on the EC
units is set to the “Source” position (positive logic, 24V DC corresponds to logical 1).
If you want to use negative logic (0V corresponds to logical 1) you must move the jumper to
the “Sink” position. Use tweezers or thin-nosed pliers to move the jumper.

Signal Terminal Terminal name Description
Input signals
Contact inputs
STF Forward rotation start
The motor rotates forward, if
a signal is applied to terminal
STF.
When the STF
and STR signals
are turned on si-
multaneously,
the stop com-
mand is given.
STR Reverse rotation start
The motor rotates reverse, if
a signal is applied to terminal
STR.
RH, RM, RL Multi-speed selection Up to 15 different output fre-
quencies can be preset.
Input terminal
function selec-
tion (Pr. 180 to
Pr. 183) changes
the terminal
functions.
MRS Output stop
Turn on the MRS signal
(20ms or longer) to stop the
inverter output.
RES RESET input
Used to reset the protective circuit activated.
Turn on the RES signal for more than 0.1 second
then turn it off.
Common
SD Common sink for contact in-
put/reference potential
A determined control function is activated, if the
corresponding terminal is connected to the ter-
minal SD (sink logic). The SD terminal is isolated
from the digital circuits via optocouplers. The ter-
minal is isolated from the reference potential of
the control circuit.
Common output terminal for 24V DC / 0.1A po-
wer output (PC terminal).
PC
24V DC output and
control input common if
source logic type is activated
24V DC/0.1A output
With negative logic and control via open collec-
tor transistors (e.g. a PLC) the positive pole of an
external power source must be connected to the
PC terminal. With positive logic the PC terminal
is used as a common reference for the control in-
puts. This means that when positive logic is se-
lected (default setting of the EC units) the corre-
sponding control function is activated by
connecting its terminal to the PC terminal.

ECAUTION
:
Terminals 10 and 5 must not be connected to each other. Otherwise the internal volt-
age output for the connection of the potentiometer will be damaged.
NOTE The control terminals RL/RM/RH/MRS (input terminals) and RUN/FU/A, B, C (output termi-
nals) can be assigned to other functions or signals with the help of the control unit
(FR-PA02-02 or FR-PU04), the PC software or a field bus system.Please see the frequency
inverter manual for details on the procedure for this.
Please note the following important points for proper frequency inverter control performance:
쎲The following conditions must be fulfilled for the frequency inverter to output a rotating field
correctly:
–The inverter lock must be deactivated (see below).
–You must input both a direction of rotation signal and a frequency setpoint value to the
inverter.
쎲If the frequency inverter does not work properly even though the wiring of the control termi-
nals block appears to be correct please check the following points:
–Is the frequency inverter reporting an error condition (red alarm LED)?
–Is the correct operating mode selected (EXT mode for control via the terminal block, PU
mode for control via the control unit)?
–Is the inverter lock (terminal MRS) deactivated and is the inverter receiving a rotation
start signal (terminal STF or STR)?
–Is the inverter receiving a valid frequency setpoint value > the start frequency (voltage
signal on terminal 2, current signal on terminal 4, preset frequency digital inputs)?
–Are the control terminals you are using programmed correctly?
