3. Commissioning<br />
Power supply unit, Order No. 77 3401 00<br />
1. Connect input and output terminal connections. (Refer to items 2.1 and 2.2)<br />
2. Switch on the input voltage.<br />
From now on, the connected nurse call system devices are supplied with 24 V DC.<br />
The green LED "Power" is on due to the voltage at the terminal clamps.<br />
