MOUNTING � Mounting Cautions (1) Use this instrument within the following ambient temperature and ambient humidity. • Allowable ambient temperature: −10 to +50 °C • Allowable ambient humidity: 5 to 95 % RH (Absolute humidity: MAX. W. C 29 g/m 3 dry air at 101.3 kPa) (2) Avoid the following when selecting the mounting location: • Rapid changes in ambient temperature, which may cause condensation. • Corrosive or inflammable gases. • Direct vibration or shock to the mainframe. • Water, oil, chemicals, vapor or steam splashes. • Excessive induction noise, static electricity, magnetic fields or noise. • Direct air flow from an air conditioner. • Exposure to direct sunlight. • Excessive heat accumulation. (3) Mounting consideration • Install the module 200 mm away from the main power line. • Ensure at least 50 mm space on top and bottom of the control unit for maintenance and environmental reasons. � Dimensions 70 3.5 60 28 φ3.5 (Unit: mm) 48 39 (13.4) � DIN rail Mounting 1. Pull down the mounting bracket at the bottom of the module (A). Attach the hooks on the top of the module to the DIN rail and push the lower section into place on the DIN rail (B). 2. Slide the mounting bracket up to secure the module to the DIN rail. (C) Locked (B) Push Mounting bracket DIN rail (A) Pull down � Panel Mounting Mount COM-K directly on the panel with screws which are inserted in the mounting holes of the top and bottom mounting brackets. Recommended tightening torque: 0.3 N⋅m (3 kgf⋅cm) The customer needs to provide the M3 size screws. Select the screw length that matches the mounting panel.

WIRING � Wiring Cautions To avoid noise induction, keep communication signal wire away from instrument power line, load lines and power lines of other electric equipment. � Method to connect (1) For loader communication Connected to loader communication connector of the controller (FB400/FB900) Connected to USB port of a personal computer USB cable Loader communication cable (W-BV-01) [Option] USB communication converter COM-K Connected to USB connector Connected to loader communication connector While loader communication is being performed, DO NOT turn on or off the instrument power supply (e.g. FB400/FB900). The loader may be stopped. Please refer to our web site http://www.rkcinst.com for how to communicate to FB series with a COM-K. The COM-K can be connected at either the power turned ON or OFF of the controller. When the power of the controller is turned off, COM-K supplies power to the controller after approximately 2 seconds. While the power is being supplied from the COM-K, the “−−−−” is displayed on the PV/SV display of the controller. (2) For RS-485/RS-422A communication RS-485/RS-422A Connected to USB port of a personal computer USB cable Connected to communication terminals of controller (Example: FB400/FB900) USB communication converter COM-K Connected to USB connector Connected to RS-485/RS-422A communication connector � Connector pin configuration 1 2 3 4 5 RS-485/RS-422A communication connector [RS-485] [RS-422A] Pin No. Signal name Symbol Pin No. Signal name Symbol 1 Signal ground SG 1 Signal ground SG 2 Send data/ Receive data T/R (A) 2 Send data T (A) 3 Send data/ Receive data T/R (B) 3 Send data T (B) 4 * Unused  4 Receive data R (A) 5 * Unused  5 Receive data R (B) * Do not connect wires to 4 and 5 pins.
