1. Caution These connectors are designed to fit together only one way Do not attempt to insert the connectors backward To do so would damage the connector and possibly the system board Making Back Panel Connections Position the connector so that the side of the connector that contains the screws is facing up Insert the prepared DPC into the NCI Back Panel with an even force The connectors are supposed to be tight to ensure a good connection Do not attempt to defeat this by loosening the connection Power Connection and Fusing Power Connection and Fusing 10 The fuse module is located on the left side of the NCI back panel see Figure 1 The fuse module contains the voltage selector and two fuse holders The NCI 901 902 is a Safety Class I device according to IEC Standard 348 that is the NCI uses a three conductor line cord Caution Before turning the unit on check that the proper line voltage has been selected in the fuse module at the back of the interface Otherwise serious damage to the interface may occur Warning Insert the main plug only in a socket outlet provided with a protective earth contact Do not disconnect the protective earth ground contact for any reason To do so is unsafe and will interfere with the proper operation of the interface Ensure that the main plug is easily accessible Do not place the NCI 901 902 in a location where the power cord is unreachable gt To change the voltage 1 Di2.

Connections 17 Secondary Relay Circuits Secondary Relay Circuits When the controlled device requires higher voltages and or currents particularly when you must switch primary power that is 120 230 VAC use a secondary relay circuit An example of such a circuit is shown in Figure 3 The NCI 901 902 relays are used to switch power to a secondary relay The secondary relay may normally be open as shown in Figure 3 or closed depending on the application The secondary relay contacts and all connecting cabling must be rated to accommodate the power requirements of the controlled device Warning You must shield all live connectors from user contact If primary power is switched have a trained technician or contractor install all circuitry in compliance with local codes The secondary relay coil voltage should match the chosen power supply less than 24 VDC and must require a current of less than 0 5 amps Note that the circuit that connects the NCI 901 902 relay and the secondary relay is powered by a DC supply and that a diode is installed across the secondary relay coil The diode shunts the inverse current generated when the secondary relay coil power is switched off minimizing electromagnetic noise that could affect the NCI 901 902 microprocessor or other digital devices nearby It is difficult to suppress such noise in an AC circuit so the DC option is strongly recommended If the controlled device draws significant power
