A.1.3 Short circuit ratings
Suitable for use in a circuit capable of delivering not more than 100 kA rms symmetrical amperes, 550 V or 600 V maxi-
mum (500 V maximum at 12-pulse rectifier power supply).
A.1.4 Machinery directive
The frequency inverter and the converter unit themselves are not a machine in the spirit of the EU machinery directive.
The start up of the final integrated system with the inverter and the converter unit in a machine is prohibited so long until it
has been confirmed that the entire machine complies with the provisions of Directive 98/37/EC (from 29.12.2009 Machin-
ery Directive 2006/42/EC).
A.2 Instructions for UL and cUL
(Conforming standard UL 508C, CSA C22.2 No.14)
A.2.1 General precautions
The bus capacitor discharge time is 10 minutes. Before starting wiring or inspection, switch power off, wait for more than
10 minutes, and check for residual voltage between terminal P/+ and N/- with a meter etc., to avoid a hazard of electrical
shock.
A.2.2 Installation
All types of the converter unit have been approved as products for use in enclosure.
Design an enclosure so that the surrounding air temperature, humidity and atmosphere of the converter unit satisfy the
specifications (refer to page 2.)
Wiring protection
For installation in the United States, Class T, Class J, Class CC, or Class L fuse must be provided in accordance with the
National Electrical Code and any applicable provincial codes (refer to the table on page 29).
For installation in Canada, Class T, Class J, Class CC, or Class L fuse must be provided in accordance with the Canada
Electrical Code and any applicable provincial codes (refer to the table on page 29).
Wiring protection (12-pulse rectifier power supply)
Refer to the connection diagram on page 29.
For installation in the United States, branch circuit protection must be provided in accordance with the National Electrical
Code and any applicable provincial codes.
For installation in Canada, branch circuit protection must be provided in accordance with the Canadian Electrical Code
and any applicable provincial codes.
Provide the appropriate fuse in accordance with the table at the top of this page.
A.2.3 Wiring of the power supply and motor
For wiring the input (R/L1, S/L2, T/L3) terminals of the converter unit and output (U, V, W) terminals of the inverter, use the
UL-listed copper wires (rated at 75 °C) and round crimping terminals. Crimp the crimping terminals with the crimping tool
recommended by the terminal maker.
A.2.4 Short circuit ratings
Suitable for use in a circuit capable of delivering not more than 100 kA rms symmetrical amperes, 550 V or 600 V maxi-
mum (500 V maximum at 12-pulse rectifier power supply).
