Select a terminal according to the main power supply voltage.
For different-voltage model (-047, -048)*
(*Wiring connection example when the voltage is 380V)
• 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.
