Installing
the Inverter
26
2.3 Cable Wiring
Open the terminal cover, remove the cable guides, and then install the ground connection as
specified. Complete the cable connections by connecting an appropriately rated cable to the
terminals on the power and control terminal blocks.
Read the following information carefully before carrying out wiring connections to the inverter. All
warning instructions must be followed.
•
Install the inverter before carrying out wiring connections.
•
Ensure that no small metal debris, such as wire clippings, remain inside the inverter. Metal debris
in the inverter may cause inverter failure.
•
Tighten terminal screws to their specified torque. Loose terminal block screws may allow the
cables to disconnect and cause a short circuit or inverter failure. Refer to page
604
.
•
Do not place heavy objects on top of electric cables. Heavy objects may damage the cable and
result in electric shock.
•
Use cables with the largest cross-sectional area, appropriate for power terminal wiring, to ensure
that voltage drops do not exceed 2%.
•
Use copper cables rated at 600 V, 75
℃
for power terminal wiring.
•
Use copper cables rated at 300 V, 75
℃
for control terminal wiring.
•
If you need to re-wire the terminals due to wiring-related faults, ensure that the inverter keypad
display is turned off and the charge lamp under the terminal cover is off before working on wiring
connections. The inverter may hold a high voltage electric charge long after the power supply has
been turned off.
•
The accessible connections and parts listed below are of protective class 0. It means that the
protection of these circuits relies only upon basic insulation and becomes hazardous in the event
of a failure of the basic insulation. Therefore, devices connected to these circuits must provide
electrical-shock protection as if the device was connected to supply mains voltage. In addition,
during installation these parts must be considered, in relation with electrical-shock, as supply
mains voltage circuits.
