UL Standards
Figure 10.1 UL/cUL Mark
The UL/cUL Mark indicates that this product satisfies stringent safety standards. This mark
appears on products in the United States and Canada. It shows UL approval, indicating that it
has been determined that the product complies with safety standards after undergoing strict
inspection and assessment.
You must use UL Listed or UL Recognized parts for all primary components that are built into
electrical equipment that has UL approval.
This product has been tested in accordance with UL standard UL61800-5-1, and has been
verified to be in compliance with UL standards.
Machines and devices integrated with this product must satisfy the following conditions for
compliance with UL standards.
■

Wire the Main Circuit Terminal Block
Wire the main circuit terminal block correctly as specified by the instructions in the manual.
To select the correct wire gauge, refer to
Main Circuit Wire Gauges and Tightening Torques on
.
Main Circuit Wire Gauges and Tightening Torques
Refer to
Single-Phase 200 V Class on page 300
Three-Phase 200 V Class on page 296
, and
Three-Phase 400 V Class on page 303
for the recommended wire gauges and tightening torques
of the main circuit terminals.
Comply with local standards for correct wire gauges in the region where the drive is used.
WARNING
Electrical Shock Hazard. Make sure that the protective ground wire conforms to technical
standards and local safety regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the
power supply to automatically de-energize when the protective ground wire disconnects. If you turn on the
internal EMC filter, the leakage current of the drive will be more than 3.5 mA. You can also connect a protective
ground wire that has a minimum cross-sectional area of 10 mm
2
(copper wire). If you do not obey the standards
and regulations, it can cause serious injury or death.
WARNING
Electrical Shock Hazard. Only connect peripheral options, for example a DC reactor or
braking resistor, to ter1, +2, -, B1, and B2. Failure to obey can cause serious injury or death.
