3.3.1 Power wiring
Emerson offers three power supplies for the Rosemount
1. 115/230 Vac power supply (01 ordering code)
2. 24 Vdc (20-30 V) power supply (02 ordering code)
3. 85-265 Vac switching power supply (03 ordering code)
AC mains (115 or 230 V) leads and 24 Vdc leads are wired to the power
supply board which is mounted vertically on the left side of the main
enclosure cavity. Each lead location is marked clearly on the power supply
board. Wire the power leads to the power supply board using the lead
markings on the board.
The grounding plate is connected to the earth terminal of power supply
input connector TB1 on the 01 (115/230 Vac) and 03 (85-265 Vac) power
supplies. The green colored screws on the grounding plate are intended for
connection to some sensors to minimize radio frequency interference. The
green screws are not intended to be used for safety purposes.
