NOTES FOR TABLE 2.1
1. Multiply the Maxim um Continuous Running Power Rating (Active Power Rating in Watts) of the
appliance / 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 Rating of the inverter should be > 4 times the
Watt Sec rating of photographic strobe / flash unit.
SECTION 3 | Limiting Electro-magnetic
Interference (EMI)
3.1 EMI 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. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in business / commercial /
industrial environments. 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.
3.2 REDUCING EMI THROUGH PROPER INSTALLATION
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.
- Shield the DC side wires with metal sheathing / copper foil / braiding:
- Use coaxial shielded cable for all antenna inputs (instead of 300 ohm twin leads).
- Use high quality shielded cables to attach audio and video devices to one another.
- Limit operation of other high power loads when operating audio / video
equipment.
