Installation

To ensure that the device is installed efficiently, follow the instructions below:
1. Even if the device can function properly at a voltage that varies between 18 and 30Vdc, always supply
a stabilised voltage that is not affected by network load variations.
2. Never leave a break in the cable shielding. If a connector or joint has to be inserted in the US3
cable, make the connection as shown as shown in the diagram:
3. The CLAMP ferrite provided with the equipment must be applied to the cable.
