B. Control circuit wiring signal
1. Separate control circuit wires from power cables to pre-
vent erroneous operation caused by noise interference.
2. Use shielded wires for control circuit wires.
3. To wire the external control signals, please refer to 6-3.
C. Grounding
1. Ground resistance less than 0.1
2. The ground wires must obey international standards and
keep the length as short as possible.
3. Never ground the inverter in common with welding ma-
chines, motors or an other large-current electrical equip-
ment. To connect all of the ground wires separate from
wires for large-current electrical equipment.
4. When using serveral inverter units side by side, ground the
units as shown in (a) or (b). Do not loop the ground wires
as shown in (c).
