Input Power Wiring 

MicroNet controls require a fixed wiring installation for ac applications. Ground leakage exceeds 3.5 mA 

AC. Maximum ground leakage for ac installations is 7.2 mA at 60 Hz. A ground conductor connected to 

the chassis is required for safety. The power supply grounding terminal(s) should also be connected to 

earth to ensure grounding of the power supply printed circuit boards. The grounding conductor must be 

the same size as the main supply conductors. 

Branch circuit fuses, circuit breakers, and wiring must meet appropriate codes and authorities having 

jurisdiction for the specific country (CE, UL, etc.). See Table 4-4 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 4-4 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.

Each main power supply has four LEDs to indicate power supply health (OK, Input Fault,

Overtemperature, and Power Supply Fault).

See MicroNet Plus Power Supply Troubleshooting (Section 5.5) for a description of the LED indications.

Input power connections are made to the power supply through a plug/header assembly on the front of

the power supply.

Power requirements depend on the number and type of modules supplied for each system. For a system 

with a single I/O chassis, size the input power source according to the rating of the MicroNet power 

supply to which the source is connected. Do not size the supply mains for the sum of the MicroNet power 

supply ratings when redundant supplies are used. MicroNet supplies are redundant when installed in the 

same chassis. Redundant supplies share the load between them equally, but each must provide for full 

load in the event that one of the units is disabled. Table 4-4 gives the maximum overload protection for 

supply mains connected to any single or redundant pair of MicroNet main power supplies. It is not 

recommended that both MicroNet main power supplies of a redundant pair be connected to a single 

source, since failure of that source would disable the system.
