C.1 UL Standards
u UL Standards Compliance
The UL/cUL mark applies to products in the United States and Canada and indicates that UL has performed product testing
and evaluation and determined that their stringent standards for product safety have been met. For a product to receive UL
certification, all components inside that product must also receive UL certification.
Figure C.1 UL/cUL Mark
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:
n Installation Area
Do not install the drive to an area greater than pollution severity 2 (UL standard).
n Ambient Temperature
IP20/NEMA Type 1 enclosure: -10 °C to +40 °C (14 °F to 104 °F)
NEMA Type 4X/IP66 enclosure: -10 °C to +40 °C (14 °F to 104 °F)
u IP66/NEMA Type 4X Conditions of Acceptability
Adhere to the installation conditions specified in this manual to take full advantage of the IP66/NEMA Type 4X design of this
drive.
n Resistance Against Chemicals and Solvents
Table C.1 lists the information on chemical and solvent tolerability of the drive. The drive enclosure meets these requirements:
• UL50E: Enclosures for Electrical Equipment, Environmental Considerations NEMA Type 4X
• International Standard IEC 60529 Degrees of protection provided by enclosures (IP Code) IP66
Refer to the appropriate enclosure specification for more details on the enclosures resistance to chemicals and solvents.
Table C.1 Chemical and Solvent Tolerability
Reagent Solvent
• Hydrochloric acid (10%)
• Sulfuric acid (10%)
• Nitric acid (10%)
• Ammonia water
• Sodium chloride
• Methanol
• Ethanol
NOTICE: Do not allow a stream of chemicals or solvents to be sprayed directly onto the drive enclosure. Failure to do so can damage the
drive.
NOTICE: Prevent moisture and other solvents from entering the drive enclosure when removing the front cover. Failing to do so can damage
the drive or considerably shorten its expected performance life.
u Main Circuit Terminal Wiring
Yaskawa recommends using closed-loop crimp terminals on all drive models. UL/cUL approval requires the use of UL Listed
closed-loop crimp terminals when wiring the drive main circuit terminals. Use only the tools recommended by the terminal
manufacturer for crimping. The wire gauges listed below are Yaskawa recommendations. Refer to local codes for proper wire
gauge selections.
