Control Wiring - Trane TR200 Operating Instructions Manual

Installation
NOTICE
IT IS THE RESPONSIBILITY OF THE USER OR CERTIFIED ELECTRICAL INSTALLER TO ENSURE CORRECT GROUND-
ING (EARTHING) OF THE EQUIPMENT IN ACCORDANCE WITHNATIONAL AND LOCAL ELECTRICAL CODES AND
STANDARDS.
• Follow all local and national codes for proper electrical equipment grounding (earthing).
• Correct protective grounding of the equipment must be established. Ground currents are higher than 3
mA.
• A dedicated ground wire is required.
• Connect the ground wire directly to a reliable earth ground. Grounding studs are provided on the back
plate of the option panel for grounding.
• Do not use conduit connected to the option panel as a replacement for a ground wire.
• Do not ground one panel to another in a "daisy chain" fashion. Each panel must have a dedicated ground
connection.
• A high strand count ground wire is preferred for dissipating high frequency electrical noise.
• Keep the ground wire connections as short as possible.

Control Wiring

Detailed instructions for terminal functions, control wiring installation, and operation is shown in Section 5
Electromechanical Bypass (EMB) Operation and Section 6 Electronically Controlled Bypass (ECB) Operation.
RUN INPUT POWER, MOTOR WIRING AND CONTROL WIRING IN THREE SEPARATE METALLIC CONDUITS
ORRACEWAYS FOR HIGH FREQUENCY NOISE ISOLATION. FAILURE TO ISOLATE POWER, MOTOR AND CON-
TROL WIRING COULD RESULT IN LESS THAN OPTIMUM DRIVE AND ASSOCIATED EQUIPMENT PERFORM-
ANCE.
• It is recommended that control wiring is rated for 600 V for 480 V and 600 V drives and 300 V for 200-240
V drives.
• Isolate control wiring from high power components in the drive.
• See label inside of panel cover for details.
