3.6.1.3 Installing an AC reactor/DC reactor
• Two options are available when the inverter is connected to a large-
capacity power transformer whose capacity is 600kVA or higher:
Transformeter
AC Reactor
Transformeter
Inverter
DC
Reactor
Figure 3.5 Reactor installation
• If not, inverter may be damaged due to an excessive peak current flow
through the input power circuit.
• AC reactor/DC reactor also can be used to improve the power factor
on input power supply side.

3.6.1.4 Connecting input power supply
• Input power supply can be connected to any terminal R/L1, S/L2, or
T/L3 on the terminal block; the phase sequences of input power
supply are irrelevant.
3.6.1.5 Installing a surge absorber
• A surge absorber must be used for inductive loads near the FARA
MOSCON-E7.
Otherwise, it may damage the devices or cause
malfunctioning.
• These inductive loads includes:
- MC,
- Electromagnetic relay,
- Solenoid valves and solenoids,
- MCCB
