Wiring Method - TDK-Lambda DRF240 Série Mode D'emploi

PA619-04-01B
(3) Press against the bottom front side for locking.
Shake the unit slightly to check the locking action.
(4) In order to tighten the unit mounting, the Din rail
stopper attached on both sides of the unit is
recommended.
8.2. Power supply removal from DIN RAIL
(1) Switch main power off and disconnect your system from
the supply network. Pull the Latch on the rear lower edge
of the unit downwards and gently lift lower front edge of
the unit (tipping upwards) and remove it.
9. Output Derating – DRF240 series

10. Wiring Method

The output load line and input line shall be separated and
twisted to improve noise sensitivity.
Use all lines as thick and short as possible to make
lower impedance.
Noise can be eliminated by attaching a capacitor to the load
terminals.
EMI reduction performance by winding the cable
a
around toroidal ferrite core several times. Use any
appropriate commecially available ferrite core from local
vendor.
For safety and EMI considerations, connect
Earth) terminal of input connector to ground terminal of
equipment.
10.1 EMC
The DRF240 complies with the provisions of the EMC
directive and meets the following standards:
Emissions: EN55022 Class B
Immunity: EN61000-4-2, -3, -4, -5, -6, -8, 11
SEMI F47 0706, GL EMC2
11. External Fuse Rating
If required a 250Vac/8A rated fuse rating should be fitted
external on input line. Surge current flows when line turns on.
Use slow-blow fuse or time-lag type fuse. Do not use fast-
blow fuse. Fuse rating is specified by in-rush current value at
line turn-on. Do not select the fuse according to input current
(RMS.) values under the actual load condition.
