CME Transistor output common A common terminal for transistor output terminals. Insulated from
terminals CM and 11.
30A,30B,
30C Alarm relay output
(for any fault) Outputs alarm signal as relay contact output (1SPDT) when inverter
stops due to alarm.
Contact capacity: 250V AC, 0.3A, cos
f = 0.3 (or 48V DC, 0.5A when
conformed with Low Voltage Directive)
You may choose to close contacts under unusual or normal
conditions.

(1) Input terminals (13, 12, and 11)
1) Shielded wires as short as possible (20m or less) should be used
for cables because these terminals handle weak analog signals
that are very susceptible to external noise. The shields should be
grounded to the earth, as a rule. If the signals are greatly affected
by external induction noise, however, connecting the shields to
terminal 11 may be advantageous.
2) When relay contacts are required in this circuit, use twin contacts
handling weak signals. Do not use contacts at terminal 11.
3) If any of these terminal is connected with an external analog signal
output unit, it may malfunction due to the noise generated by the
inverter, depending on the analog signal output circuit. In this
case, connect a ferrite core or capacitor to the external analog
signal output unit.
