3 Safety Precautions

! WARNING

Serious injury may possibly occur due to loss of required safety functions. Do not use test outputs of the DST1 as any safety outputs. Serious injury may possibly occur due to loss of required safety functions. Do not use DeviceNet standard I/O data or Explicit message data as any safety data. Serious injury may possibly occur due to loss of required safety functions. Do not use LEDs on the DST1 for safety operations. Serious injury may possibly occur due to breakdown of safety outputs. Do not connect loads beyond the rated value to the safety outputs. Serious injury may possibly occur due to loss of required safety functions. Wire the DST1 properly so that DC24V line do NOT touch the safety outputs accidentally or unintentionally. Serious injury may possibly occur due to loss of required safety functions. Ground the 0V line of the power supply for external output devices so that the devices do Not turn ON when the safety output line is grounded.

For Model DST1-MRD08SL-1, Apply only one AC line phase to the relays output

For Model DST1-MRD08SL-1, Insert a fuse rated at 3.15A or less for each output terminal to protect safety output contacts from welding.

Confirm the fuse selection with the fuse manufacturer to ensure the dependability of the characteristics of the connected load. Serious injury may possibly occur due to loss of safety functions. Use appropriate devices according to the requirements given in the following table.

Controlling devices Requirements

Emergency stop switches Use approved switches with a direct opening mechanism complying with IEC/

EN 60947-5-1. Door interlocking switches Limit switches

Use approved switches with a direct opening mechanism complying with IEC/

EN 60947-5-1 and capable of switching micro-loads of 5 mA at 24 V DC.

Safety sensor Use approved sensors complying with the relevant product standards, regula-

tions, and rules in the country where it is used. Relay with forcibly guided

contacts

Use approved devices with forcibly guided contacts compliant with EN 50205.

For feedback, use devices with contacts capable of switching micro-loads of

4 mA at 24 VDC. Contactor Use approved relays with forcibly guided contacts complying with EN 50205.

For feedback purpose, use devices with contacts capable of switching micro-

loads of 5 mA at 24 V DC. Other devices Evaluate whether devices used are appropriate to satisfy the requirements of

safety category.

4 Precautions for Safe Use

Handle with care

Do not drop the DST1 to the ground or excessive vibration or mechanical shocks. The DST1 may be damaged and may not function properly.

Installation and storage environment

Do not use or store the DST1 in any of the following locations.

• Locations subject to direct sunlight.

• Locations subject to temperatures or humidity outside the range specified in the specifications.

• Locations subject to condensation as the result of severe changes in temperature.

• Locations subject to dust (especially iron dust) or salts

• Locations subject to dust (especially iron dust) or salts.

• Locations subject to water, oil, or chemicals.

• Locations subject to shock or vibration. Take appropriate and sufficient countermeasures when installing systems in the following locations. Inappro-

priate and insufficient measures may result in malfunction.

• Locations subject to static electricity or other forms of noise.

• Locations subject to strong electromagnetic fields

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.

Installation/ Mounting

• Use the DST1 within an enclosure with IP54 protection or higher of IEC/EN 60529.

• Use DIN rail (TH35-7.5 according to IEC60715) for placing the DST1 into the control board.

• Mount the DST1 to DIN rails with attachments (TYPE PFP-M, not incorporated to this product), not to drop out of rails by vibration etc.

• Spacing should be available around the DST1 at least 50mm from its top and bottom surfaces for ventilation and wiring.

Installation/ Wiring

• Use the following to wire external I/O devices to the DST1.

• Disconnect the DST1 from power supply when wiring. Devices connected to DST1 may operate unexpectedly.

• Apply properly specified voltages to the DST1 inputs. Applying inappropriate DC voltage and any AC voltages cause the DST1 to fail.

• Be sure to separate the communication cable and the I/O cable from the high-voltage/ current lines.

• Be cautious not to have your fingers caught when attaching connectors to the plugs on the DST1.

• Mount screw of DeviceNet Connector and I/O Connector correctly(0.25-0.3 Nm).

• Incorrect wiring may lead to loss of safety function. Wire conductors correctly and verify the operation of the DST1 before commissioning the system in which DST1 is incorporated.

• After wiring is completed, be sure to remove label for wire clipping prevention on the DST1 to enable heat to escape for proper cooling

Power Supply Selection

Use DC power supply satisfying requirements below.

• Secondary circuits of DC power supply is isolated from its primary circuit by double insulations or reinforced insulations

• DC power supply satisfies the requirement for class 2 circuits or limited voltage/current circuit stated in UL 508.

• 20ms or over of the output hold time.

Solid wire 0.2 ~ 2.5 mm2 AWG 24 ~ 12 Standard (Flexible) wire 0.34 ~ 1.5 mm2 AWG 22 ~ 16

Standard wire should be processed with insulation-covered bar terminal (DIN46228-4 standard compatible type) at its ends before using for connection.

Periodical Inspection and Maintenance

• Disconnect the DST1 from power supply when replacing. Devices connected to the DST1 may operate unexpectedly.

• Do not dismantle, repair, or modify the DST1. It may lead to loss of its safety functions.

Disposal

• Be cautious not to have you injured when dismantling the DST1.
