    8. Maintenance and Inspection Proceed with daily inspection and periodic inspection to prevent malfunction and ensure long-term reliability. Note the following: 8-1 Daily Inspection During operation, a visual inspection for abnormal operation is completed externally without removing the covers The inspections usually cover the following: (1) The performance (satisfying the standard specification) is as expected.

  • Page 89 8-3 Measurement of Main Circuit Electrical Quantity The indicated values depend on the type of meter because the harmonic component is included in the voltage and current of the main circuit power (input) and the output (motor) side of the inverter. When measuring with a meter for commercial power frequency use, use the meters shown in Table 8.3.1.

Compliance with Standards 9-1 Compliance with UL/cUL Standards 9-1-1 Overview The UL standard is an abbreviation for Underwriters Laboratories Inc. and is a safety standard for preventing fires and other accidents, and protecting users, servicemen, and general people in the United States. The cUL standard is a standard which the UL constituted to meet the CSA standard.
