Connecting The Tim To The Power Supply - Siemens SIMATIC TIM 3V-IE DNP3 System Manual

Installation and commissioning
4.2 Mounting and connecting up a TIM
4. If you are connecting the TIM to an external modem, the insert the 9-pin D-sub connector
of the modem connecting cable into the X1 or X2 connector of the TIM 4R-IE DNP3 and
screw it tight.
5. Connect the TIM to the S7-CPU(s) or the PC of the control center. With a
TIM 4R-IE DNP3, this is via Ethernet.
6. Once the wiring is completed, the power supply can be turned on.
The TIMs start up. The LEDs on each TIM indicate the current start-up activities, refer to
the section Commissioning the TIM (Page 70).
7. Once it has started up, the TIM can be supplied with its parameters (SDBs) using the
SINAUT diagnostics and service tool.
With the TIM 3V-IE DNP3 and the TIM 4R-IE DNP3, the SDBs can also be loaded on the
memory card of the S7-300 CPU, with the TIM 4R-IE DNP3, you can also use the
optional C-PLUG of this module for storage. The TIM receives then its configuration data
from the CPU during startup or takes it from the inserted C-PLUG.

Connecting the TIM to the power supply

Connecting up only with power off
Connecting the TIM module to a live power supply can damage the module. Connect the
module to the power supply only when the power supply is off.
SELV
The power for the device (24 V DC) must be generated as a safe extra low voltage. This
means it must be a SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low
Voltage) according to DIN VDE 0100 Part 410 (IEC 60364-4-41).
Cables
To wire the power supply, use flexible cables with a cable cross-section of 0.25 ...0.75 mm
If you wire only one cable per connection, no wire-end ferrule is necessary.
