Safety Precautions
3
For the DST1-MRD08SL-1, isolating transformers, such as TR1, that are used to
isolate between overvoltage categories III and II must conform to IEC60742, and
the insulation between the primary input and secondary output must satisfy at
least the basic insulation standards of overvoltage category III. One side of the
secondary output of the isolating transformer must be grounded to prevent
electrical shock in case of short-circuiting to the ground or to the frame of the
isolating transformer. To protect the isolating transformer and to prevent electri-
cal shock in case of short-circuiting to the frame, insert fuses according to
transformer specifications, i.e., at points F1, F2, and F3.
Serious injury may possibly occur due to loss of required safety functions.
Clear the previous configuration data before connecting devices to the network.
Serious injury may possibly occur due to loss of required safety functions. Set
suitable node addresses before connecting devices to the network.
Serious injury may possibly occur due to loss of required safety functions. Per-
form user testing and confirm that all device configuration data and operations
are correct before starting system operation.
Serious injury may possibly occur due to loss of required safety func-
tions.When replacing a device, configure the replacement device appropriately
and confirm that it operates correctly.
For Model DST1-MRD08SL-1, insert a fuse rated at 3.15 A or less for each output
terminal to protect safety output contacts from welding. Confirm the fuse selec-
tion with the fuse manufacturer to ensure the dependability of the characteris-
tics of the connected load.
Serious injury may possibly occur due to loss of safety functions. Use appropri-
ate devices according to the requirements given in the following table.
