The type ‘(a)’ that has substantial cooling effect is recommended.
CAUTION
1. The ambient temperature condition for the power supply unit or the drive units is 55°C or less.
2. Because heat can easily accumulate in the upper portion of the units, give sufficient consideration to heat dissipation
when designing the panel. If required, install a fan in the panel to agitate the heat in the upper portion of the units.
