Power Supply Board replacement
1. If replacing the Power Supply board remove power to the meter.
2. Disconnect the Transmitter Electronics Enclosure security seals, loosen the end cap
security latches with a 3mm Allen wrench and remove both end caps (see
Figure 3-15).
3. Use a flat head screw driver and remove the terminal blocks from the Power Supply
board, the CPU Module and the Optional I/O Module (if installed). See Figure 3-10 for
board locations and associated terminal blocks.
4. Use a Phillips head screw driver and remove the four Backplane board screws from
the enclosure standoffs. If the Local Display Module is installed on the Backplane,
use a flat blade screw driver and install the four flat-head screws into the enclosure
standoffs.
