3. MOUNTING

To prevent electric shock or instrument failure, always turn off the power before mounting or removing the instrument.

3.1 Mounting Cautions

(1) This instrument is intended to be used under the following environmental conditions.

(IEC 61010-1) [POLLUTION DEGREE 2]

(2) Use this instrument within the following environment conditions:

• Allowable ambient temperature: − 10 to + 50 ° C

• Allowable ambient humidity: 5 to 95 %RH

(Absolute humidity: MAX. W. C 29.3 g/m 3 dry air at 101.3 kPa)

• Installation environment conditions: Indoor use

Altitude up to 2000 m

(3) Avoid the following conditions 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 dust, salt or iron particles.

• Excessive induction noise, static electricity, magnetic fields or noise.

• Direct air flow from an air conditioner.

• Exposure to direct sunlight.

• Excessive heat accumulation.

(4) Mount this instrument in the panel considering the following conditions:

• Ensure at least 50 mm space on top and bottom of the instrument for maintenance and environmental reasons.

• Do not mount this instrument directly above the equipment that generates large amount of heat

(heaters, transformers, semi-conductor functional devices, large-wattage resistors.)

• If the ambient temperature rises above 50 ° C, cool this instrument with a forced air fan, cooler, etc.

Cooled air should not blow directly on this instrument.

• In order to improve safety and the immunity to withstand noise, mount this instrument as far away as possible from high voltage equipment, power lines, and rotating machinery.

High voltage equipment: Do not mount within the same panel.

Power lines:

Rotating machinery:

Separate at least 200 mm.

Separate as far as possible.

• For correct functioning mount this instrument in a horizontal position.

• Be sure the COM-ML and function modules are joined when using them.

Bottom

(5) In case this instrument is connected to a supply by means of a permanent connection, a switch or circuit-breaker shall be included in the installation. This shall be in close proximity to the equipment and within easy reach of the operator. It shall be marked as the disconnecting device for the equipment.

3.2 Joining Each Module

Before joining the COM-ML and function modules, use the DIP switch to make the communication settings. For the setting procedure, refer to 5. HOST COMMUNICATION

SETTINGS (rear side).

The maximum number of function modules (Z-TIO-A/B, Z-DIO-A) described in the following can be joined per COM-ML. For details on joining function modules with the COM-ML, refer to the Z-TIO

INSTRUCTION MANUAL (IMS01T01-E  ) .

• When joining function modules of the same type: Up to 16 modules

• When joining function modules of two or more different types: Up to 30 modules

(However, the maximum joinable number of function modules of the same type is 16.)

Procedure for mounting or removing

The procedure for mounting or removing the COM-ML is the same as that of the function module

(Z-TIO-A/B or Z-DIO-A). Both DIN rail mounting and screw mounting are available.

For the mounting or removing, refer to the Z-TIO INSTRUCTION MANUAL (IMS01T01-E  ) .

4. WIRING

To prevent electric shock or instrument failure, do not turn on the power until all the wiring is completed. Make sure that the wiring has been properly made before applying power to the instrument.

4.1 Wiring Cautions

• To avoid noise induction, keep communication signal wire away from instrument power line, load lines and power lines of other electric equipment.

• If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.

− Shorten the distance between the twisted power supply wire pitches to achieve the most effective noise reduction.

− Always install the noise filter on a grounded panel. Minimize the wiring distance between the noise filter output and the instrument power supply terminals to achieve the most effective noise reduction.

− Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness of the noise filter.

• Power supply wiring must be twisted and have a low voltage drop.

• For an instrument with 24 V power supply input, supply power from a “SELV” circuit defined as IEC 60950-1.

• A suitable power supply should be considered in end-use equipment.

The power supply must be in compliance with a limited-energy circuits (maximum available current of 8 A).

• Select the power capacity which is appropriate for the total power consumption of all joined modules (including COM-ML) and the initial current surge when the power is turned on.

Power consumption (at maximum load): 120 mA max. (at 24 V DC)

Rush current: 12 A or less

• When connecting the wiring to the terminals on the base, use the specified solderless terminals. Only these specified solderless terminals can be used due to the insulation between the terminals.
