In the case of the standard type and semi-standard type
（−Ｃ，−Ｈ ，−Ｔ ，−046）, connect the line to X1M.
In the case of “with breaker” （−B） specifications,
connect to the circuit breaker.
In the case of the semi-standard type （with transformer：−047，−048）,
connect the line to the terminal block supplied with the transformer.

1. Always install an all-pole (3-pole) circuit breaker (to be prepared
by you) of the specified capacity on the main power supply.
*All contact distances must be at least 3 mm.
2. Always ground the unit. Since a noise filter is installed, there
is a risk of electrical shock without proper grounding.
3.
Before opening the electric component box, always turn off the power,
and wait for 5 minutes until internal high voltage has been discharged.
4. Do not energize the equipment with the electric component
box kept open.
DANGER
1. To avoid the effects of noise, connect the power wire by
cutting it to the proper length so that no excess wire comes
into contact with the control board or others.
2. To perform remote control, remove the short-circuit wire
between [10] and [11] and install an operation switch （to be
prepared by you）.
3. The mode is set to “Lock mode （Stop mode）” by default.
Before starting operation, follow the procedure to release the
Lock mode from the operation panel. Refer to the operation
manual for the unlocking procedure.
4. The unit is provided with a misoperation prevention switch
(PROTECT) to reject setting from the operation panel.
If you want to use this function, make the necessary setting
referring to the operation manual.
CAUTION
1. The following electric wires can be used on the
terminal block for straight crimp-style terminals.
Single wire: φ０．57∼φ１．44（ＡＷＧ＃22∼＃16 ）
Stranded wire: ０．25mm

∼1．25mm

（ＡＷＧ＃２２∼１６）
2. Load applicable to [60 - 64] and [66 - 67] is as follows:
Min. applicable load: 10mV DC, 10μA or more
Max. applicable load: 30V DC, 2A （Resistance load）
3. For [10] to [13], please prepare contacts to meet
the condition of minimum applicable load 12V DC
and 5mA.
4. When the length of the thermistor to be connected
to [30] − [31] is longer than 10m, or the wiring is
routed in a poor noise environment, use shielded
wire.
CAUTION
2. Use a straight crimp-style terminal for connection.
3. Use stranded wires for electric connection.
4.
The wiring size is 0.5 mm
2
to 1.5 mm
2
in the case of duplex cable according
to IEC. If using stripped wire, make the stripped length 9 mm to 10 mm.
