4.2 Mounting and connecting up a TIM
TIM DNP3
66 System Manual, 12/2015, C79000-G8976-C253-04
If the cable or conduit entry point exceeds 70 °C or the branching point of conductors
exceeds 80 °C, special precautions must be taken. If the equipment is operated in an air
ambient in excess of 50 °C, only use cables with admitted maximum operating temperature
of at least 80 °C.
Take measures to prevent transient voltage surges of more than 40% of the rated voltage.
This is the case if you only operate devices with SELV (safety extra-low voltage).
Notices on use in hazardous areas according to UL HazLoc
DO NOT DISCONNECT WHILE CIRCUIT IS LIVE UNLESS AREA IS KNOWN TO BE

This equipment is suitable for use in Class I, Zone 2, Group IIC or non-hazardous locations
only.
Installing the TIM modules
Both DNP3 TIM types can be installed as a CP in an S7-300 device.
Only 1 DNP3 TIM per station.
Only 1 DNP3 TIM can be installed per S7 station.
The TIM 4R-IE DNP3 can also be mounted as a standalone device on an S7-300 rail and
then communicates via Ethernet with S7-400, S7-400H or S7-300 CPU modules and/or a PC
control center.
The following sections describe how to mount the devices as a CP or standalone device.
