Although Harmonic provides the power input connector with the Electra-9200D, you must
supply the wires.
The wires must comply with the specifications shown in Table 2–2.
Power Connector
The encoder is supplied with a special DC power connector plug that matches the DC power
socket on the back of the encoder.
This connector is made by WAGO, model number 231-103/037-000.
Use only the original connector for connecting the encoder to the DC power source. Contact
Harmonic Technical Support (Appendix D, Contacting the Technical Assistance Center) if you want to
use any other type of connector.
Figure 2–7 shows the connector and its strain relief housing.
