compability
If your site is suscepble to problems with electromagnec compability (EMC), parcularly
from lightning or radio transmiers, seek expert advice.
Strong sources of electromagnec interference (EMI) can cause:
• Destrucon of the signal drivers and receivers in the device,
• Electrical hazards as a result of power surges conducted over the lines into the equipment.
