For redundant operation, the control can use any combination of power supplies.
The power supplies can only be installed into slots PS1 (power supply #1) and PS2 (power supply #2). If
redundant power supplies are not needed, blanking plates must be installed in the slots not being used.
Branch circuit fuses, circuit breakers, and wiring must meet appropriate codes and authorities having
jurisdiction for the specific country (CE, UL, etc.). See Table 4-3 for maximum recommended fuse or
breaker ratings. Do not connect more than one main power supply to any one fuse or circuit breaker. Use
only the wire sizes specified in Table 4-3. which meet local code requirements. Time delay fuses or circuit
breakers must be used to prevent nuisance trips.
In the event that on supply needs to be replaced, the recommended method for changing
Power Modules is with the power off (to the module being removed and the module being inserted).
The system will tolerate this “cold swap” method without failure.
System Power-Up
If at any time during this procedure the defined or expected result is not achieved, begin system
troubleshooting.
1. Verify that the entire MicroNet Plus control system has been installed.
2. Turn on the power to one power supply and verify that the power supply’s green LED is the only
power supply LED on.
3. Turn off the power to the first power supply and turn on the power to the second power supply (if a
second power supply is present) and verify that the power supply’s green LED is the only power
supply LED on.
4. The RTN_CPUs in the chassis will not start automatically, the CPUs in the TMR chassis must
command them to start. See GAP application program for details.
