Russound CAM6.6T-S1 Instruction Manual page 20

CAUTION
Do not connect the controller's main power feed until all other connections have been
made and verified. Live connection or removal of the keypad wiring or other wiring
when the system is powered can cause communication problems in the network.
Double-check terminations during each phase of the installation to prevent accidental
damage. Incorrect wiring is the number one cause for non-warranty product damage.
