Wiring of main circuit (FR-HC2-7.5K to 75K, FR-HC2-H7.5K to H220K)
(2) Wiring of reactor 1 and outside box
• Cable size differs by the capacity. Select an appropriate cable by referring to 2.6.3 Cable sizes of the main control circuit
terminals and earth (ground) terminals (refer to page 31) and perform wiring.
• The 400V class outside box is equipped with a MC power supply stepdown transformer. Switch the tap (V1, V2, V3) of the
stepdown transformer according to the input power supply voltage as shown in the table below.
Power Supply Voltage
380V or more, less than 400V


Use the enclosed screws (M5) for the wiring of FR-
HCB2-7.5K, 15K and FR-HCB2-H7.5K to H30K.
NOTE
• Because the reactor heats up, install the reactor in a place where the outside box will be unaffected by heat.
• Perform wiring where the wire sheath does not touch the reactor.
• Do not remove or wire the whirl-stop (shown on the right diagram) of
the crimping terminals (R2/L12, S2/L22, T2/L32) of FR-HCB2-H160K
and H220K.
