Connection Of A Dc Reactor (Fr-Hel) - Mitsubishi Electric FR-D720-0.2K-G Instruction Manual

2.4.5

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.)
(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.
(3) DC reactor (FR-HEL) is electrically connected to the enclosure through mounting screws when the DC reactor is
securely mounted to the enclosure. If the DC reactor is not earthed (grounded) securely enough, an earthing (grounding)
cable may be used.
When you are using an earthing (grounding) cable, wire the cable to the mounting hole where varnish is removed. (Refer
to the Instruction Manual of FR-HEL.)
NOTE
 The wiring distance should be within 5m.
 The size of the cables used 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 16.)
 Do not connect a DC reactor (FR-HEL) to the drive unit when FR-HC2 or FR-CV is connected.
