Outline of electrical equipment box (Typical)
Connection of remote control input
To execute remote control, connect the cable according to the procedure below.
Local procurement items
Remove the short-circuit bar (between terminals [10] and [11]) on the terminal block in
the electrical equipment box.
(For the crimp tool, use the specified tool.)
Connect the cable specified in above between terminals [10] and [11].
∗
12 VDC is applied across these terminals (Terminal [10]: negative polarity, [11]: positive polarity).
Component
Single-pole, single-throw remote control switch, or “a” contact that enables operation command output
Note) Select a switch whose minimum allowable load is 12 VDC and 5 mA.

• Protect switch (erroneous operation prevention)
The factory default setting of this switch is OFF but some nonstandard units are set to ON.
Pay attention when you attempt to change any of the operation setting, parameter setting or timer setting.
• CN2 (OP2 terminal)
Alarm will be generated on malfunction by connecting an external protecting device and setting the parameter
(n003) (see "Alarm Setting for Optional Protecting Device (Installed by user)" on page ).
• CN11
Replace this connector with the outlet oil temperature thermistor when you attempt returned oil temperature control.
• CN12
Connect the lead provided in the unit to the optional communication board.
