3.11 Wiring Checklist
NOTICE: Check all the wiring to ensure that all connections are correct after installing the converter and connecting any other devices.
Failure to comply could result in damage to the converter. To get the full performance life out of the electrolytic capacitors and circuit
relays, refrain from switching the converter power supply off and on more than once every 30 minutes.
No.
Converter, Peripherals, Option Cards
1 Check converter model number to ensure receipt of correct model.
2 Make sure you have the correct peripheral devices.
3 Check the option card model number.
Installation Area and Physical Setup
4 Ensure that the area surrounding the converter complies with specifications.
Power Supply Voltage, Output Voltage
The voltage from the power supply should be within the input voltage specification range of the
5
converter.
6 The total load must be within the output specifications of the converter.
A power supply with a capacity (kVA) that is larger than the rated input capacity of the converter must
7
be used.
8 The ratings must be correct.
Main Circuit Wiring
9 Confirm proper branch circuit protection as specified by national and local codes.
10 Properly wire the converter.
11 Suitable wires must be used to wire the power supply and converter.
12 Properly ground the converter. Review page 61.
Check that the screws for the converter's main circuit terminals and the ground terminal have been
13 fastened using the specified torque.
Refer to
Control Circuit Wiring
14 Use twisted-pair line for all converter control circuit wiring.
15 Ground the shields of shielded wiring to the GND
16 Properly wire any option cards.
17 Check for any other wiring mistakes. Only use a multimeter to check wiring.
Check that the screws for the converter's control circuit terminals have been fastened using the
18
specified torque. Refer to
19 Pick up all wire clippings.
20 Ensure that no frayed wires on the terminal block are touching other terminals or connections.
21 Properly separate control circuit wiring and main circuit wiring.
The line between the input-side AC reactor and converter must be 10 m or shorter and the DC bus line
22
between the converter and drive must be 5 m or shorter.
