[Overview of Terminals and Connectors]
The terminal blocks and connectors for wiring are located behind the electrical access door (upper
front panel door).
[Usage for the External connection terminal block 1 (TB1)]
● Applicable cable size : AWG26 to 18 (Φ0.4 to 1.0) (Note1)
● Wire covering to be stripped : 8 to 9 mm
(Note1)
Since the applicable wire size for terminal block TB1 has acquired UL approval with
AWG26 to 20, when using under conditions equivalent to UL Standards, use AWG26
to 20 wire.
Faulty wiring causes the substrate breakdown.
Before wiring, be sure to confirm the terminal signal.
