(1) General Precaution
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.
(2) Environment
Before installation, check that the environment meets following specifications.
Surrounding Air Temperature is a temperature measured at a measurement position in an enclosure. Ambient Temperature is a temperature outside an enclosure.

or less for the 160K or higher
(3) Installation
High power factor converter (FR-HC2) and its accessories are open type devices which must be installed inside a separate
and suitable Type 1 enclosure along with the external components (Input reactors, Magnetic Contactor, Pre-Charge
Resistor, Capacitors and Transformer).
Make the necessary wiring connections in accordance with the NEC for installations in North America, CEC for Canada and
any applicable local codes.
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 below.
Due to Type 1 enclosure variables of size, cooling fans, ventilation and location, be sure to monitor the surrounding air
temperature of the converter to not exceed 50
C. Use additional cooling means as necessary.
Install all appended accessories inside the enclosure.
