Connect a full-scale 1 mAdc DC ammeter or full-scale 7 .SVdc-1 mA DC
voltmeter to the control terminals.
The contact rating of the protection operation detection relay (FL) is
250Vac
(cos¢' =0.4) 30Vdc-1A.
A max. of 24dc
-1
OOmA
can be used from the P24 control power
terminal to drive external relays.
The RCH and LOW control terminals are open-collector output, and
can output a max. 24Vdc-50mA.
Use of a 24Vdc OMRON
MY1
relay
(RY)
is
recommended.
Always install a diode (200V-1 A class)
for surge absorption. Take
special note
of the diode
polarity to avoid incorrect
application.

Use a potentiometer rated at 1 k to 1
Ok
Q-1 /4W for the frequency-
setting input signal.
The
clearance between terminals on the inverter main circuit terminal
block
is
small, so use sleeved crimp-on terminal lugs for all main
circuit terminals. Take
special care during connection so that the
terminal lugs do not make contact with neighboring terminal lugs.
Always ground the G/E grounding terminal with a wire that is 3.5mm
2
or larger.
For inverter capacities that are 3.7kW or less, a built-in braking
resistor is connected between the main circuit terminals
(PA
1)
and
(PB1), providing dynamic braking as a standard feature.
The
(E)
terminal is for internal connections,
so
do not remove
connections from it or make any
external connections to it.
