Proper Wiring Sizing
• Always size wire gauges as specied by the National
Electrical Code (NEC) for electronic control devices.
• For improved noise immunity, install one size larger
wire gauge than the NEC requirement to assure am-
ple current-carrying capability.
• Never under size wire gauges.
Voltage Source
• Transformers block a large percentage of
Electromagnetic Interference (EMI). It is recom-
mended that the Vilter MicroVission should be iso-
lated with its own control transformer for the most
reliable operation. See Figure 1-1: MicroVission with
Individual Transformer.
• Avoid connecting MicroVission to breaker panels
and central control transformers if possible as the
MicroVission is exposed to large amounts of EMI
emitted from the other devices connected to the sec-
ondary terminals of the transformer. See Figure 1-2:
EMI and MicroVission.
