Installing the Inverter
Wiring
Follow the seven steps for Cover removal, Ground Wire, Power Wire, Control Wire connections and
EMC Filter connection. Complete the cable connections by connecting appropriately rated cables
for ground, 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 cut-offs, 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 short circuits or inverter failure. Refer to
on page
•
Do not place heavy objects on top of electric cables. Heavy objects may damage the
cable and result in electric shock.
•
Verifiy the power supply system for this equipment (inverter) is a grounded system.
When connected to an ungrounded or asymmetrical grounded power supply, refer to
Step 6, Disabling of the EMC filter
.
•
The equipment may generate direct current in the protective ground wire. When
installing the residual current device (RCD) or residual current monitoring (RCM), only
Type B RCDs and RCMs can be used.
•
Use cables with the largest cross-sectional area, appropriate for power terminal wiring,
to ensure that voltage drop does 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.
•
Separate control circuit wires from the main circuits and other high voltage circuits (200
V relay sequence circuit).
•
Check for short circuits or wiring failure in the control circuit. They could cause system
failure or device malfunction.
•
Use shielded cables for control terminal wiring. Failure to do so may cause malfunction
due to interference. When grounding is needed, use shielded twisted pair (STP) cables.
•
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 front 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.
