z SAFETY PRECAUTIONS z (Always read before starting use) When using this equipment, thoroughly read this manual. Also pay careful attention to safety and handle the module properly. These precautions apply only to this equipment. Refer to the User’s Manual of the CPU module to use for a description of the system safety precautions. These "Safety Precautions" classify the safety precautions into two categories: "DANGER" and "CAUTION".
[WIRING PRECAUTION] DANGER z Completely turn off the externally supplied power used in the system when installing or placing wiring. Not doing so may cause electric shock or damage to the product. CAUTION z Check the layout of the terminals and then properly route the wires to the module. z Solder connectors for external device properly. Insufficient soldering may cause malfunction. z Be careful not to let foreign matter such as sawdust or wire chips get inside the module.

5. Wiring DANGER z Completely turn off the externally supplied power used in the system when installing or placing wiring. Not doing so may cause electric shock or damage to the product. 5.1 Wiring Precautions (1) Always confirm the terminal layout before connecting the wires to the QD75. (2) Correctly solder the external wiring connector. An incomplete soldering could lead to malfunctioning. (3) Make sure that foreign matter such as cutting chips and wire scraps does not enter the QD75.
(9) If cables to connect to QD75 absolutely must be positioned near (within 100 mm) the power line, use a general shielded cable. The shield must be grounded on the QD75 side. Connector Connector (A6CON1/A6CON2) Shielded cable To external devices To external device To drive unit To QD75 Use the shortest possible length to ground the 2mm2 or more FG wire. (The shield must be grounded on the QD75 side.) The length between the connector and the shielded cables should be the shortest possible.
Wrap the coated parts with a heat contractile tube. (10) To make this product conform to the EMC directive and low voltage instruction, be sure to use the AD75CK type cable clamp (manufactured by Mitsubishi Electric) for grounding to the control box. Inside control box QD75 20cm(7.88inch) to 30cm(11.82inch) AD75CK Using the AD75CK, you can tie four cables of about 7mm (0.28inch) outside diameter together for grounding.
5.2 External Interface The internal circuits of interface for connecting external devices to the QD75 are shown by the schematic diagrams in the tables below (for the QD75P1 and QD75D1).

5.3 Wiring of the differential driver common terminal When the differential driver output type (QD75D1/QD75D2/QD75D4) is used, an inter-common potential difference may occur between the differential driver common terminal and the differential receiver common terminal of the drive unit. To eliminate an inter-common potential difference, connect between the differential driver common terminal of the QD75D1/QD75D2/QD75D4 and the differential receiver common terminal of the drive unit.
