NOTES
:
1
)
Follow
local
codes
and regulations when selecting field wires.
2
)
The wire sizes marked in the table are selected at the maximum current of the unit according to the
European Standard , EN60335-1.Use the wires which are not lighter than the ordinary polychloroprene
sheathed flexible cord (code designation H07RN-F) .
When
connecting
the terminal block using flexible cord, make sure to use the round crimp-style terminal
for connection to the power supply terminal block.
Place the round crimp-style terminals on the wires up to the covered
part and secure in place.
When
connecting
the terminal block using a single core
wire, be sure to perform curing.
3
)
When transmitting cable length is more than 15 meters, a larger wire size should be selected.
4
)
Use a shielded cable for the transmitting circuit and connect it to ground .
