■ Fan power source switching connector “CN R”, “CN W” (types FRN0203 E2■-4

or above)
FRENIC-Ace supports direct current power supply input with PWM converters in the standard specification.
However, FRN0203 E2■-4 or above contains parts which are driven by AC power supply such as the AC fan, so
AC power must also be supplied. When using DC power for the inverter, move connector “CN R” to NC side, move
connector “CN W” to FAN side, and connect an AC power source to the auxiliary power input terminals for the fan
(R1, T1).
For details on the switching procedure, refer to “Figure 2.2-23 Switching Connector Positions” and “Figure 2.2-24
Attachment and Removal of the Switching Connector”.

• DC bus input type
• Combination with PWM converter

The fan power source switching connector “CN R” is on FAN and “CN W” is on NC when shipped from
the factory. When direct current
power supply input is not used, do not modify this setting.
Mistakes in the fan power
source
switching connector setting may prevent the cooling fan from operating,
and alarms such as cooling fin overheat
0h1 and charging circuit error pbf may be generated.
