  Power source connection procedure
Check the current capacity of the distribution board before wiring. The wiring must be performed by
a professional engineer.
WARNING
 Be sure to switch off the breaker at the distribution board before connecting this product to the
distribution board. Otherwise, an electric shock might occur.
1. Remove the resin-molded cover of power input and output panel in case DP060LM / DP120LM
or that of power input panel in case DP180LM.
2. Connect the power cable to the power input terminal of this product. Be sure to tighten the
screws firmly.
3. Attach the resin-molded power input and output / input terminal cover so that the cables pass
through the cutout.
4. Ensure that the power switch of this product is turned off, and then connect the power cable to
the distribution board.
CAUTION
 Be sure to check phases L, L1, L2, L3 and N are correctly connected between this product and
the distribution board.
 If this product whose power input is three-phase four-wire input (3P4W) is used without
connecting N, it may be damaged. Be sure to connect all power cables.
WARNING
 Do not use this product when the resin-molded terminal cover is removed. Otherwise, an electric
shock might occur.
 Use enough thick cables to prevent touching live conductive parts after attaching the
resin-molded terminal cover. If a thin cable is connected, fingers may enter the gap between the
resin-molded terminal cover and the cable, resulting in electric shock, therefore attach some
additional guards.
