NOTES:
1. HIGH-FREQUENCY GROUNDING USING HEAVY BRAIDS SHOULD CONNECT TOGETHER THE ELECTRONIC EQUIPMENT, THE ELECTRICAL ENCLOSURE, THE
MACHINE FRAME AND THE MOTOR HOUSING.
2. THE INTERNAL SHUNT RESISTOR IS ONLY PRESENT ON THE 2092-DA3, 2092-DA4, AND 2092-DA5 MODELS. B1 AND B2 SHOULD BE LEFT DISCONNECTED ON
THE 2092-DA1 AND 2092-DA2 MODELS.
3. AN ISOLATION TRANSFORMER IS OPTIONAL. IF USED, THE SECONDARY OF THE TRANSFORMER MUST BE GROUNDED.
4. THE 2092-DA1 AND 2092-DA2 MODELS HAVE ONE GROUNDING SCREW ON THE HEATSINK, AND THE 2092-DA3, 2092-DA4, AND 2092-DA5 MODELS HAVE TWO
GROUNDING SCREWS ON THE HEATSINK.
5. THE 2092-DA1, 2092-DA2, AND 2092-DA3 MODELS ARE SINGLE-PHASE AC INPUT, AND L3 SHOULD BE LEFT DISCONNECTED.
6. THE JUMPER FROM P1 TO P2 CAN BE REPLACED WITH AN INDUCTOR, IF THE POWER FACTOR OR HARMONIC DISTORTION NEEDS IMPROVEMENT.
