Power supply grounding and wiring
When connecting power to the AZW-5000, ensure that one leg of the VAC 
secondary circuit connects to a known earth ground. Also ensure that the GND 
terminal on the AZW-5000 connects to the same known earth ground.
Supplying a high-quality ground connection to a AZW-5000 and then properly 
connecting the AZW-5000 to the ground is one of the most important things you 
can do to ensure a trouble-free installation.
The 24VAC secondary leads are not interchangeable. Once a lead connects to 
the GND terminal on the AZW-5000, it is the grounded lead. Observe and 
maintain polarity for subsequent connections. The GND terminal provides a 
reference ground for the circuit board and communications wiring. Use 18 AWG 
cable for best results.

Ensure that all AZW-5000 power, communications, and I/O 
cabling are grounded according to these instructions. Failure to follow these 
instructions may result in AZW-5000 operational and communication failures or 
equipment damage.
Power supply wire selection
If you are considering long power supply wiring runs, using the right wire size is 
critical. If the wire diameter is too small, the resistance may be too high, 
resulting in a low voltage supply to the AZW-5000. This is known as line loss. 
The wire size is based on the length of the wire run and the current draw of the 
AZW-5000. Obtain additional information from the transformer manufacturer.
