2.3 Assembly of the ERC-M RS232 PCB
Assemble and solder the components according to the following drawings.
Please read the following instructions before you start:
1. The vertical assembled Diodes should have a distance (1-2mm) to the PCB while soldering.
Otherwise there is the risk of overheating these components while soldering.
2. Take care of polarization of the following components (marked red in the assembly drawing):
- Diodes D1,D2,D3,D4,D5,D6,D9,D10,D11,D13,D14
- Capacitor Al C5
- Capacitor tantal C7,C8,C17,C18,C19,C20
- IC-socket for IC1,IC2,IC3
- Transistor T1,T2
- Voltage-regulator IC4
- Box-header X3
3. Carefully compare the position of the PCB with the drawings before you start to assemble it.
