Using Only One SERVOPACK
• Wiring Example for Three-Phase, 200-VAC Power Supply Input: SGD7S-R70A, -R90A,
-1R6A, -2R8A, -3R8A, -5R5A, -7R6A, -120A, -180A, -200A, and -330A
* You do not have to connect B2 and B3 for the following models: SGD7S-R70A, SGD7S-R90A, SGD7S-
1R6A, and SGD7S-2R8A. Do not connect them.
