7.2 Connection<br />
The connection is carried out in accordance with below figure. Please note, that the load resistor must have a<br />
value between 250 and 500Ω .<br />
The minimum power supply is 13.5V + (RL*20mA) ; RL = load resistor<br />
The maximum power supply is 30V.<br />
As connection cable a protected twisted cable pair is recommended.<br />
