CAUTION:
Disconnect All Communication Loop Wiring

Then Reconnect Communication Loop Wiring.
24 VAC Transformer
Size For 6 VA Max. Load
Some Installers Like To Use One Large 24 VAC Transformer
To Power Several Devices. This Is Allowable As Long As
Polarity Is Maintained To Each Device On The Transformer
Circuit.
Using Separate Transformers Also Allows Redundancy In
Case Of A Transformer Failure. Instead Of Having 8 Devices
Inoperative Because Of A Malfunctioning Transformer, You
Have Only 1 Device Off Line.
WARNING: If Polarity Is Not Maintained, Severe Damage
To The Devices May Result. AAON Recommends
Using A Separate Transformer For Each Device In Order
To Eliminate The Potential For Damaging Devices Due To
Incorrect Polarity.
CAUTION:
Disconnect All Communication Loop Wiring
From The MiniLink Before Removing Power
From The Controller. Reconnect Power And
Then Reconnect Communication Loop Wiring.
