3.1 Input Power Supply, Molded-case Circuit

Breaker, and Fuse

Use input power supplies that meet the following conditions.

• The main circuit power supply must be a 24-VDC or a 48-VDC power

supply.

• The control circuit power supply must be a 24-VDC power supply.

• The main circuit power supply and the control power supply must be two

separate input power supplies.

• Power supplies must have double or reinforced insulation that conforms

to safety standards.

• Current limiting function is required for AC/DC converter which is used

for main circuit power supply. The current limiting specification must be

50A or less to prevent short-circuit current exceeds 50A under short cir-

cuit condition.

• External branch circuit protection must be provided in accordance with

the National Electrical Code and local codes.

When choosing molded-case circuit breakers and fuses for input power sup-

plies on the AC side, confirm the specifications of the input power supplies

and refer to this table.

Also, choose molded-case circuit breakers and fuses that meet the following

cutoff characteristics.

Cutoff characteristics (25°C): ⋅300% of the rated load input current, five

seconds min.

⋅Does not cut off at the inrush current value

of the power supply.

* 1. Values with instantaneous maximum load.

* 2. Values with rated load.
