Connection of a DC reactor (FR-HEL)

(1) Keep the surrounding air temperature within the permissible range (-10C to +50C). Keep enough clearance
around the reactor because it heats up. (Take 10cm or more clearance on top and bottom and 5cm or more on left
and right regardless of the installation direction.)
5cm or more
(2) When using the DC reactor (FR-HEL), connect it across terminals P/+ and P1.
In this case, the jumper connected across terminals P/+ and P1 must be removed. Otherwise, the reactor will not
exhibit its performance.
Since the DC reactor (FR-HEL) is electrically connected to the enclosure through mounting screws, the DC reactor is
earthed (grounded) by being securely mounted to the enclosure. However, if the DC reactor is not earthed (grounded)
securely enough, an earthing (grounding) cable may be used. When using an earthing (grounding) cable, wire the cable
to the installation hole where varnish is removed. (Refer to the Instruction Manual of FR-HEL.)
NOTE
 The wiring distance should be within 5m.
 As a reference, the cable gauge for the connection should be equal to or larger than that of the power supply cables
(R/L1, S/L2, T/L3) and the earthing (grounding) cable. (Refer to page 17)
 DC reactor connection is not available when Filterpack is connected.
