Description:

• Read and understand this manual before installing, operating, or servicing this Drive. All warnings, cautions, and

instructions must be followed. All activity must be performed by qualified personnel. The Drive must be installed according

to this manual and local codes.

• Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is

on. Do not remove or insert the digital operator while power is on.

• Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply

is turned off. Status indicator LEDs and Digital Operator display will be extinguished when the DC bus voltage is below

50 VDC. To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage level

to confirm safe level. 

• Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged

by high voltage.

• The Drive is not suitable for circuits capable of delivering more than the specified RMS symmetrical amperes. Install

adequate branch short circuit protection per applicable codes. Refer to the specification. Failure to do so may result in

equipment damage and/or personal injury.

• Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the

output of the Drive. These devices may generate peak currents that exceed Drive specifications.

• To avoid unnecessary fault displays caused by contactors or output switches placed between Drive and motor, auxiliary

contacts must be properly integrated into the control logic circuit.

• YASKAWA is not responsible for any modification of the product made by the user; doing so will void the warranty. This

product must not be modified. 

• Verify that the rated voltage of the Drive matches the voltage of the incoming power supply before applying power.

• To meet CE directives, proper line filters and proper installation are required.
