Fan power supply switching connectors (CN R and CN W) (on inverters of 60 HP or above for 230 V and those of
125 HP or above for 460 V)
The standard FRENIC-MEGA series accepts DC-linked power input in combination with a PWM converter. Inverters of 60 HP or
above for 230 V and those of 125 HP or above for 460 V, however, contain AC-driven components such as AC fans. To supply AC
power to those components, exchange the CN R and CN W connectors as shown below and connect the AC power line to the
auxiliary fan power input terminals (R1, T1).
For the switching instructions, see Figures 2.6 and 2.7.

When using terminals R1 and T1
• Feeding the DC-linked power
• Combined with a PWM converter
Note:
A box (
) in the above figure replaces S or H depending on the enclosure.
By factory default, the fan power supply switching connectors CN R and CN W are set on the FAN and NC positions,
respectively. Do not exchange them unless you drive the inverter with a DC-linked power supply.
Wrong configuration of these switching connectors cannot drive the cooling fans, causing a heat sink overheat alarm
0h1
or a charger circuit alarm

Location of the switching connectors
The switching connectors are located on the power printed circuit board (power PCB) as shown below.
