6. Connect the TIM to the same power supply as the CPU.
7. 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 and screw it
tight.
Note
The standard connecting cable 6NH7701-4AL for connecting the modem to a TIM module
(RS-232) is connected to the MD2, MD3 or MD4 modem "head first" so that the cable
comes away towards the top.
With a TIM 4, the standard connecting cable is also connected from above. With the
TIM 3V-IE variants and the TIM 4R-IE, the cable is connected from below.
8. If you are using a TIM 4R / 4RD and require the supplied interface adapter cable
6NH7 700-0AS00, insert this in the second X3 interface located on the underside of the
device and connect it via a modem connecting cable to the required modem.
9. If a DCF77 radio clock is installed in a TIM 4, the BNC plug of the antenna cable must be
screwed to the BNC socket of the DCF77 adapter cable.
10.To install further TIMs in a rack, follow the same steps as described above.
Note
With a TIM 3V-IE, only one TIM module may be installed per S7-300. This means that
TIM modules of other types cannot be added either.
11.Once all the TIMs are installed, the power supply can be turned on. The TIM starts up.
The LEDs indicate the current start-up activities (see separate section
12.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 variants and the TIM 4R-IE,
the SDBs can also be loaded on the memory card of the S7-300 CPU, with the
TIM 4R-IE, 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.

Installing a TIM 4 / TIM 4R-IE as a standalone device
Order of installation
To install the TIM 4 or TIM 4R-IE as a standalone device on an S7-300 rail, follow the steps
below in the order shown:
1. Place the TIM on the standard rail and push it in towards the bottom.
2. Screw the TIM securely into position.
3. Connect the TIM to the power supply. Since this is a separate TIM rack, this does not
need to be the power supply of the CPU with which the TIM is connected over MPI or
Ethernet.
