Safety
•
Mains wiring should only be carried out by a qualified
electrician.
•
Ensure suitable protective devices are fitted on the mains
supply to the Hub.

Ensure all cabling and connected devices meet the
specifications stated in this installation guide.
•
Use the cable strain relief provided inside the Guru Hub.

Securely fix all cables between the Hub and connected
devices.
