NOTICE
Do not disconnect the wiring to the converter and harmonic filter module while the converter is outputting a
voltage.
Improper equipment sequencing could result in damage to the converter.
When connecting a converter, use a power supply with a capacity that is the same or higher than the capacity
calculated by the power supply capacity selection formula in
Selecting the Power Supply Capacity on page 17
.
Failure to comply could result in damage to the converter.
Observe proper electrostatic discharge procedures (ESD) when handling the converter, circuit boards, and
CMOSIC.
Failure to comply may result in ESD damage to the converter circuitry.
Do not perform a withstand voltage test on any part of the converter.
Failure to comply could result in damage to the sensitive devices within the converter.
Do not operate damaged equipment.
Failure to comply could result in further damage to the equipment.
Do not connect or operate any equipment with visible damage or missing parts.
Install adequate branch circuit short circuit protection per applicable codes.
Failure to comply could result in damage to the converter.
The converter is suitable for circuits capable of delivering not more than 100,000 RMS symmetrical Amperes, 240 Vac
maximum (200 V Class) and 480 Vac maximum (400 V Class).
Prevent foreign matter such as metal shavings or wire clippings from falling into the converter during converter
installation and project construction.
Failure to comply could result in damage to the converter. Place a temporary cover over the top during installation. Be
sure to remove the temporary cover before start-up, as the cover will reduce ventilation and cause the converter to
overheat.
Never lift the converter up while the cover is removed.
This can damage the terminal board and other components.
Do not perform signal checks during operation.
Failure to comply could result in damage to the converter.
Check the following items before you turn on the power supply.
Failure to comply could result in damage to the converter and harmonic filter module.
• Is the power supply voltage correct?
200 V Class: AC190 to 240 V 50/60 Hz
400 V Class: AC380 to 480 V 50/60 Hz
• Are the converter and the control devices connected properly (e.g., is the phase order correct)?
• Is the phase order correct between the main circuit terminals (R/L1, S/L2, and T/L3) on the converter and the power
supply voltage detection terminals (r1/ 11, 1/ 21, t1/ 31).
• Are the control circuit terminals on the converter connected properly to the control devices?
• Are the Run Commands for the converter and the control devices turned off?
Replace the cooling fan correctly according to instructions in this manual.
Incorrect cooling fan mounting direction will prevent sufficient cooling of the converter and could damage internal
circuits.
