Installing and putting a TIM into operation
5.5 Installing a TIM
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.
Wiring
To wire up the power supply module with a TIM, follow the steps below:
1. Open the front panels of the power supply unit and the TIM.
2. Connect the power supply cables from the power supply unit to the TIM: M and L+
3. Close the front panels.
Wiring diagram
The figure below shows the wiring diagram for one or more TIMs of the type TIM 3 or TIM 4.
Instead of a TIM, a SINAUT ST7 modem of the type MD2, MD3 or MD4 can also be
installed. The same wiring diagram applies to these modules.
Figure 5-42
The next figure shows how to connect up the TIM 3V-IE variants and the TIM 4R-IE.
