Power Source Connections
Before You Begin
• The recommended installation wire gauge is 16 AWG (1.29mm diameter or cross-sectional area of
1.30 mm 2 ) for the power supply wires at a length of 300 meters (1000 feet). The minimum wire
gauge is 18 AWG (1.02 mm or cross-sectional area of 0.82 mm 2 ).
• When tightening small terminal blocks, use a torque between 0.5 N*m (4.43lbf*in) and 0.6 N*m (5.2
lbf*in) to fasten a wire gauge from 16 AWG to 18 AWG (from a diameter of 1.29 mm or a cross-sec-
tional area of 1.30 mm
2 to a diameter of 1.02 mm or a cross-sectional area of 0.82mm 2 ).
• Disconnect supply before servicing.
What You Should Know
1. Locate the Automation or Safety terminals on the EDGE Weather Station to connect.
2. Connect the wires (24V and GND) from the EDGE Weather Station to the network.
Consult the wiring diagrams to see the maximum cable distance according to the wire gauge.
IMPORTANT: Make sure to connect the same identifications together and to use the same network
from one side to the other
IMPORTANT: If redundancy supplies are not used, use the Automation bus.
WARNING
Installation must only be performed by qualified service personnel.
