NOTES FOR TABLE 1.6:
1 Multiply the Maximum Continuous Power Rating (Active Power Rating in Watts) of the appli-
ance / device by the recommended sizing factor to arrive at the Maximum Continuous Running
Power Rating of the Inverter.
2 For photographic strobe / flash unit, the Surge Power of the inverter should be > 4 times the
Watt Sec rating of photographic strobe / flash unit.
1.3.4 electro-magnetic interference (emi) and fcc compliance
These inverters contain internal switching devices that generate conducted and radiated
electromagnetic interference (EMI). The EMI is unintentional and cannot be entirely eliminated.
The magnitude of EMI is, however, limited by circuit design to acceptable levels as per limits
laid down in North American fCC Standard fCC Part 15(b), Class b. These limits are designed
to provide reasonable protection against harmful interference when the equipment is operated
in a residential environment. These inverters can conduct and radiate radio frequency energy
and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. The effects of EMI will also depend upon a number of
factors external to the inverter like proximity of the inverter to the EMI receptors, types and
quality of connecting wires and cables etc. EMI due to factors external to the inverter may be
reduced as follows:
• Ensure that the inverter is firmly grounded to the Ground System of the building or the
vehicle.
• Locate the inverter as far away from the EMI receptors like radio, audio and video
devices as possible.
• Keep the DC side wires between the battery and the inverter as short as possible.
• Do NOT keep the battery wires far apart. Keep them taped together to reduce their
inductance and induced voltages. This reduces ripple in the battery wires and improves
performance and efficiency.
