[. . . ] When using the Ethernet module, refer to the `Ethernet installation and Wiring Guide' (6F8C0879) CAUTION Always ground the model 2000. Failing to ground the unit can cause electrocution or malfunction. 2. 4. 1 Grounding Tips Note the following when grounding: (1) The model 2000 unit must not be a conductor for grounding current of other devices. (Especially, high frequency current can cause trouble. ) (2) The grounding potential of the model 2000 base and expansion unit must be equal. (Ground at single point. ) (3) Do not connect to ground of motorized system (require high frequency separation) (4) Do not connect to unstable ground (parts with unstable impedance such as screwed on painted parts or parts affected by vibration) 14 Computer m odule SATELLITE 5100-201PU37 User's Manual 2. 4 Grounding 2. 4. 2 Grounding method (1) Grounding of control panel In the case of connecting panel, the ground current flowing from the high frequency device or power panel may flow through the PC housing panel. Power panel Ground current change change Power panel Power panel Isolate model 2000 mounting panel and connect to the ground point separately Isolate model 2000 from the mounting frame and connect to the ground point separately. 6E8C1111 15 Chapter 2 Installation (2) Grounding connection between base PS Basic unit FG PS Expansion unit PS Expansion unit Board internal ground terminal Dedicated ground · Connect the FG terminal of the power supply module to the unit mounting screw, 2 and to the ground bar in the panel by 2mm or larger wire in shortest possible distance. · Use a dedicated ground for the control circuit, and keep the ground cable away from that for high-power systems. · 100¶ or less to earth is recommended. (3) Line Filter ground (LG) terminal The LG terminal is a neutral point of the primary power supply line filter. It can suppress the effect caused by the noise from power supply line, by grounding the LG terminal. Therefore, normally, ground the LG terminal together with the FG terminal. However, depending on the power system, leakage current to the ground from the LG may cause problems. In this case, install an isolated transformer in the power line, or open the LG terminal. Use crimp terminal with width of 7mm or less for M3. 5 screw. 6E8C1111 19 Chapter 2 Installation 2. 6 Connector Connection Connect each connector to the peripheral device as described below. CAUTION · Turn off the power of the main unit and peripheral device when connecting peripheral devices. Connecting with the power on may cause injury or burn. · Be sure to hold the connector when attaching/removing signal cables. Otherwise, the cable may be damaged causing fire or electrocution. Important · Check the shape of the connector and insert the cable properly into the main unit. The pins may break or bend if unnecessary force is applied. · If the cable connector is equipped with fastening screws, tighten them so that the cable does not come loose. (1) Check that the switch of the power module is in the OFF position. (2) Connect the cable of each peripheral device to the main unit connector. After connecting, tighten two screws and fasten the connector to the module. Match the connectors properly when connecting and connect firmly. 20 Computer m odule SATELLITE 5100-201PU37 User's Manual Chapter, R 3. 1 Power On and Power Off Handling If you are using peripheral devices, connect them before turning on the main unit power. Important · Wait at least 5 seconds when turning on the power after turning it off. If the power is turned back on too quickly, the rush current prevention circuit may not function properly and a sudden flow of current (approximately 100A) may cause the power supply fuse to blow out. 3. 1. 1 Turning On the Power Configure the external circuit to power on in the following sequence: (1) Turn on the AC power to the power supply module. [. . . ] A Check Is the device near the TV or radio?Is the device plugged into the same outlet as TV or radio?Action Change the direction of the indoor radio or television antenna. Change the direction of the unit with respect to radio or television. [. . . ]
