Installation Environment Section 3-1
■ Current-temperature Characteristic (G3PW-A260E)
• At least 20 mm must be provided on the left and right sides of the G3PW-
A260E. Refer to 3-2 Installation. If you must use side-by-side mounting,
then reduce the maximum load current when the ambient temperature is
over 30
°
C.
• Certification for safety standards was obtained with a mounting interval of
20 mm.
• Leave sufficient space for ventilation.
• Do not install the Power Controller above devices that generate significant
amounts of heat, such as heaters, transformers, and high-capacity resis-
tors.
• If the ambient temperature reaches 55
°
C or higher, install an air condi-
tioner to lower the temperature.
Note If more than one Power Controller is installed side-by-side or vertically, the
heat that is generated will cause the internal temperatures of the Power Con-
trollers to rise and will shorten their service life. Take suitable measures, such
as installing fans for forced-air cooling.
Improving Noise
Immunity
• Do not install the Power Controller in a control panel together with high-
voltage devices.
• Install the Power Controller at least 200 mm away from power lines.
■ Recommended External Noise Filter
We recommend installing a noise filter on the primary side to improve noise
immunity.
Recommended filter: RSMN-series Filters from TDK-Lambda Corporation
RSMN-2030: For 20 A
RSMN-2060: For 45/60 A
Refer to 3-3-5 Wiring an External Noise Filter for wiring methods.
