Aligning the GPS antenna

Proceed as follows:

1. Install the GPS antenna.

2. Align the antenna vertically to the sky.

With other angles the synchronization can fail temporarily because a satellite is not in the

reception window.

Note

Do not install the GPS antenna at locations where there is a risk of lightning strikes

occurring.

If nothing else is possible, attach the GPS antenna to the inside of high windows.

Further information

● Additional information on the connection and optimal alignment of the GPS receiver can

● Additional information on connecting a central plant clock can be found in the Operating
