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 Switching Tap Position
380V or more, less than 400V V1
400V or more, 440V or less V2
More than 440V, 460V or less V3
<Wiring example of 7.5K>
The terminal arrangement differs by capacity. Check the terminal arrangement on 6.3
Outline dimensions (refer to page 150).
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.
