DANGER Devise an emergency stop circuit, interlock circuit, and other similar circuits outside the programmable controller. Disregarding this rule may result in damage to the equipment or cause an accident if the programmable controller fails. Keep it in mind that this hardware unit operates on a high voltage. If the user touches a high-voltage terminal inadvertently during connection or disconnection of this hardware unit or its cable, he or she may suffer from an electric shock.
Page 5
REQUIREMENT An electric shock may lead to a death or burn. Noise may cause the system to malfunction. Ground the line ground (LG), frame ground (FG), and shield (SHD) terminals, as described below. • Electrically insulate the mount base from the cubicle. To assure this, do not remove the insulating sheet from the mount base.

1 BEFORE USE Environment Operate the Programmable Controller in the following environment: Table 1-1 Operating Environment Supply voltage 100 to 120 VAC, single-phase, 50/60 Hz±4% Amplitude range 85 to 132 VAC Temperature At operation: 0 to 55°C; storage: -20 to 75°C Relative humidity At operation: 30 to 90% RH;...
1 BEFORE USE Grounding point Provide Class D* or better independent grounding. Do not use any other existing ground as a substitute. It is particularly important that the grounding point for the Programmable Controller be at least 15 m away from an AC panel grounding point. * Class D grounding is defined in the Technical Standard for Electrical Facilities of Japan.
User must not replace internal parts of the Programmable Controller with anything other than the parts specified in the manual. Replace the entire module in which a defective part is included. For details on parts replacement, contact your Hitachi maintenance personnel. Module insertion/removal Power must be turned off while a module is inserted or removed.
1 BEFORE USE Grounding * Inspection of the ground wiring. − Check if a ground wire is shared with another ground wire. − Check if the grounding point is at least 15 m away from the grounding point of the AC panel.

4 INSTALLATION DANGER You may be electrified if you install/remove a module or connect/disconnect a cable when power is ON by inadvertently touching a power supply terminal due to the presence of a high voltage. Also, note that a short circuit or noise may render the machine defective.
IR.LINK module of the CPU unit to the FG terminal of the CPU unit mount base and the FG terminal of the IR.Station module of the I/O unit to the FG terminal of the I/O unit mount base respectively. This connection puts their grounding potentials at the same level, makes the grounding performance higher, and consequently increases the noise resistance.
Page 37
5 CABLING An example of wiring when modules in different I/O units are connected When connecting modules in different I/O units, leave the FG terminal of the IR.Station module open. If connected, the noise resistance will decrease because of different grounding potentials.
5 CABLING 5.2 Connecting the Line Cables Always terminate the CPU module (master station) and the IR.Station module which are at both ends of the line. The terminating resistance is 120 ohms (built-in) or any (externally connected). When using an external terminating resistor, select it according to the characteristic impedance of the cable.

6 SETTING 6.1 I/O Address Setting (1) Input and output modules can be mounted any place in the mount base (free location). A module in a slot always has the same I/O address whether the module is an input module or an output module.
6 SETTING 6.2 Startup Procedure Start Check wiring (particularly the power supply wiring). Set the rotary switch correctly. Check the rotary switch setting. Check the number of points of the Set the number of points of I/O module. the I/O module correctly. Turn on power.
7 MAINTENANCE 7.1 Preventive Maintenance For optimum use of the S10mini, it is essential that you carry out the following maintenance ever now and then (at least 2 times a year). Preventive maintenance items Module appearance check Screw/terminal strip screw looseness check Cable/wire coating check Dust adhesion check AC supply voltage check (85 to 132 V)
7 MAINTENANCE Dust adhesion check Check if dust or other foreign matter adhered on the module. If any dust/foreign matter buildup is found, remove it with a vacuum cleaner. If you allow dust or other foreign matter to build up, the internal circuitry may be shorted or to cause a component burnout. Supply voltage check Check that the voltages of the module power supply and externally supplied power are within the specified ranges.
