Connection Mode (Take example by Circuit Breakers)               

1.     The connections that its direct current for Circuit Breaker assistant loop.

2.     The connections that its alternating current for Circuit Breaker assistant loop.

Installation Mode                                            

MGZ2000 indicator installation

1)      Take down back cover of indicator

2)      Take down nut, outer sleeve and gaskets

3)      Encasedφ25 install hole of switchboard, installed gaskets, outer sleeve and fasten nut.

4)      According the diagram of connections access line of control and check electrode pass

         affirm, then install back cover. (See drawing 1)

         ZL-SS220 rectifier install

1)      Take down bolt and reed on connection pole of indicator

2)      Take indicator connection pole into faucet of rectifier (See drawing 2)

3)      Fasten bolt on hole 1,+2,+3 by turns, to order to good connection with connection pole of

         indicator and circuitry board of rectifier.

4)      Check and affirm connection with indicator and rectifier.

The process of test mode as following:

1.  Measure by multimeter

     The resistance 0.1kΩ3.0 kΩ between 1 and 1, or else the connection is error.

2.  Measure by DIODE of digital multimeter.

     The red probe be connected 2, black probe be connected+2, shall display about 500, or

     else the connection is error.

3.  Measure by DIODE of digital multimeter.

     The red probe be connected 3, black probe be connected +3, shall display about 500, or

     else the connection is error.

     If the connection be estimative is error, and loosening bolt 1, +2,+3,  then check it and

     connect renew.

     Repeat above process and test by turns, until good connection by affirmed.

Note                                                        

When check and accept & installation, the indictor pole +2 and +3 shall control electricity positive pole, the indictor pole 1 shall control negative pole. The connection of positive pole and negative pole be must right.
