4.5.3 Connection of power cord
(1) Before obtaining access to terminals, all supply circuits must be disconnected.
(2) If units are type I electrical appliances, they must be reliably grounded.
(3) Ground resistance must be in accord with requirements of local standard.
(4) The green-yellow wire within units are ground wire. Do not use it for other purposes. Nor should it be
cut off or secured by tapping screws. Otherwise, it may cause electric shock.
(5) Power supply at user side must have reliable ground terminal. Do not connect ground wire to the
following places:
1) Water pipe.
2) Gas pipe.
3) Drainage pipe.
4) Other places that are considered by professionals as unreliable.
(6) Power cord and communication wire should be separated, with a distance of more than
20cm(7-7/8in.). Otherwise, system’s communication may not work well.
Steps of power cord connection:
(1) Knock off the cross-through opening that’s used for leading the external power cord, with
the cross-through rubber ring on the opening. Then lead the cable through the opening.
Connect L1, L2, L3 of power cord and ground wire separately to the positions on wiring
board (for power supply) that are marked with L1, L2, L3 and the ground screw nearby.
(2) Fasten the power cord with cable tie.
(3) Lay the power cable and communication cable for the ODU according to the marker of
external connection circuit diagram.
