Environmental conditions
The TDM880i can be installed in an environment meeting the specifications shown in Table 1.
Tools and installation materials
The TDM880i is to be mounted on mechanics using ø 3 mm screws (5 pcs) suitable for a printed circuit board. The
screw type depends on the material (metal/wood/plastic). For the detailed dimensions of the TDM880i, see Figure
10 and Figure 11.
Cable types, making of cables
Depending on your application and its environmental conditions, you should consider the requirements relevant to
your cables, for example:
• Direct exposure to sunlight
• Common chemicals such as
• alcohol
• isopropanol
• petrol
• sun lotion and hand creams
• insecticides.
All the cables and other materials must be selected so that they tolerate the conditions in your application and its
environment.
Power cable
The Airbus Defence and Space power cable CA-124 consists of a matching board-to-wire connector and of three
separate stripped wire ends. The wire ends should be connected to a power supply (to a battery or another DC
supply) so that the black wire is GND (0V), the green wire is the IGS signal, and the red wire is the VCC signal (10.6
- 16.0 V). The maximum recommended length of the power cable is 1.5 meters. If a longer cable is needed, the
voltage drop and inductance of the cable should be taken into consideration; fast load transients may cause the
input voltage to drop below the operational limits of the device.
• Cable diameter minimum AWG 14
• The pinout is given in Section Power supply on page 31.
• Recommended cable suppliers: Carol Cable, Dearborn, Belden, Alpha Wire, West Penn Wire.
• Connector suppliers: Tyco Electronics, Conec, Amphenol, Molex, JST.

TDM880i environmental conditions
WARNING:
Do not install the TDM880i in a dusty environment. If the module and the heat sink are dusty,
they can overheat.
WARNING:
When cutting and joining cables, take care not to drop pieces of cables and thin copper wires on
the TDM880i module, because they can cause short-circuits in the module.
