Operating Environment Precautions
4
■
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.
• Properly apply the specified voltage and current to the DST1 inputs. Con-
necting a DC power supply that exceeds the ratings, connecting any AC
power supply, or applying any current that exceeds the specified I/O
power supply current to the I/O terminals may result in failure of the spec-
ified functions, may diminish safety functions, or may damage the DST1
(including burning damage).
• Do not wire any other Units or external devices from the I/O power supply
terminals of the DST1.
• Be sure to separate the communication cable and the I/O cable from the
high-voltage/ current lines.
• Be careful not to catch your fingers when attaching connectors to the
plugs on the DST1.
• Mount the screws on DeviceNet Connectors and I/O Connectors correctly
(0.25 to 0.3 N·m).
• Incorrect wiring may lead to loss of safety function. Wire conductors cor-
rectly and verify the operation of the DST1 before commissioning the sys-
tem in which DST1 is incorporated.
• After wiring is completed, be sure to remove label for wire clipping preven-
tion on the DST1 to enable heat to escape for proper cooling.
■
Power Supply Selection
Use a DC power supply that satisfies the following requirements.
• The secondary circuits of the DC power supply must be isolated from its
primary circuit by double insulation or reinforced insulation.
• The DC power supply must satisfy the requirements of class 2 circuits or
limited voltage/current circuit stated in UL 508.
• The output hold time must be 20 ms or longer.
• The DC power supply must satisfy the SELV requirements given in IEC/
EN 60950-1 or EN 50178.
■
Periodical Inspection and Maintenance
• Disconnect the DST1 from power supply when replacing it. Devices con-
nected 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 careful not to get injured when dismantling the DST1.
