■ %(DUTY) Lit when the duty value is monitored in the monitor level.

■ %(OUT) Lit when the output value is monitored in the monitor level.

■ %(PHASE) Lit when the phase angle is monitored in the monitor level.

Changing from monitor level to adjustment level or from monitor level to initial setting level is possible even when an error occurs.

In the monitor level, the ENT/RST Key functions as a Reset Key only when an error occurs. (It does not function as a Reset Key when there is no error.)

A : Installation with 20 mm between Power Controllers B : Close mounting

Note: 1. The ambient operating temperature range is −15 to 55°C, but take the following considerations into account. When the ambient

temperature exceeds 40°C, reduce the maximum load current as shown below.

2. At least 20 mm must be provided on the left and right sides of the G3PW-A260E@. If you must use side-by-side mounting, then reduce the maximum load current when the ambient temperature is over 30°C.

3. Certification for safety standards was obtained with a mounting interval of 20 mm.

4. Leave sufficient space for ventilation.

5. Do not install the Power Controller above devices that generate significant amounts of heat, such as heaters, transformers, and high-

capacity resistors.

6. If the ambient temperature reaches 55°C or higher, install an air conditioner to lower the temperature.
