YASKAWA ELECTRIC TOEP C710616 33A YASKAWA AC Drive L1000A Quick Start Guide 7
Precautions for CE Low Voltage Directive Compliance
This drive has been tested according to European standard EN61800-5-1, and it fully complies with the Low Voltage
Directive. The following conditions must be met to maintain compliance when combining this drive with other devices:
Do not use drives in areas with pollution higher than severity 2 and overvoltage category 3 in accordance with IEC664.
Ground the neutral point of the main power supply for 400 V Class drives.
In the drives LC2A0145/0185 and LC4A0112/0150 the wire bending space (space between terminals and cable entry
point) provided is smaller than recommended in the IEC61800-5-1.
Precautions for UL/cUL Standards Compliance
This drive is tested in accordance with UL standard UL508C and complies with UL requirements. The following
conditions must be met to maintain compliance when using this drive in combination with other equipment:
Do not install the drive to an area greater than pollution severity 2 (UL standard).
Use UL-listed copper wires (rated at 75°C) and closed-loop connectors or CSA-certified ring connectors. For details
refer to the Technical Manual.
Wire low voltage wires with NEC Class 1 circuit conductors. Refer to national state or local codes for wiring. Use a class
2 (UL regulations) power supply for the control circuit terminal. For details refer to the Technical Manual.
This drive has undergone the UL short-circuit test, which certifies that during a short circuit in the power supply the
current flow will not rise above 100,000 amps maximum at 240 V for 200 V class drives and 480 V for 400 V class
drives.
The drive internal motor overload protection is UL listed and in accordance with the NEC and CEC. The setup can be
done using the parameters L1-01/02. For details refer to the Technical Manual.
Note: The UL listing of the drives LC2A0145/0185 and LC4A0112/0150 is pending.
Do not modify the drive circuitry.
Failure to comply could result in damage to the drive and will void warranty.
Yaskawa is not responsible for modification of the product made by the user. This product must not be modified.
Check all the wiring to ensure that all connections are correct after installing the drive and connecting other
devices.
Failure to comply could result in damage to the drive.
Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection
devices to the output of the drive.
Using unapproved filters could result in damage to the drive or motor equipment.
Check the motor rotation and elevator movement direction prior to starting up the drive.
The drive puts out voltage in phase sequence U-V-W with an Up command. Make sure the elevator moves up if the
motor is supplied with this phase sequence.
Always remove the ropes when performing Rotational Auto-Tuning.
During Rotational Auto-Tuning the drive turns the motor for a certain time. Not removing the ropes might result in
damage to the equipment.
When using a PM motor, make sure the motor can handle the maximum current delivered by the drive.
Operating the motor with too high current may result in demagnetization.
