. NEMA Type 3R/3RHE Bypass Power Circuit.
NOTES for Figure 3:
1. Branch circuit protection to be provided by installer, per UL508A, if not provided with drive.
2. For bypass operation, modify these drive parameters: P0704 (0) and P0704 (1) = 3.
3. Control and communication wiring should be 300V UL minimum.
4. Communication wiring should be run with maximum separation possible from all other wiring.
5. Essential service mode operates the motor full speed (bypass) with no protection for the motor or system.
6. Ensure that automatic bypass will not damage the system before activating.
7. See Siemens Publication No. 125-3377 for proper fuse and wire sizes.
8. See Siemens Publication No. 125-3201 for SED2 VFD input/output signal wiring details.
