WIRING
Wiring Safety
AT INSTALLATION, BE SURE TO COMPLY WITH THE FOLLOWING REQUIREMENTS:
• Disconnect power to the unit before attempting any connection or service to the unit.
• Do not bundle or route signal lines with power lines.
• Keep all lines as short as possible.
• Use twisted pair shielded wire for all output wiring.
• Observe all applicable, local electrical codes.
• Use only the type of power source suitable for electronic equipment. If in doubt, contact your distributor. Make sure
that any power cables are of a sufficiently high current rating.
• All units must be grounded to eliminate risk of electric shock.
• Failure to properly ground a unit may cause damage to that unit or data stored within it.

Follow these steps:
1. Disconnect power to the unit.
2. Completely remove the two screws from either the left or the right side of the transmitter.
