* Do not apply continously. Requires external coil economizer. Other special coil
voltages available upon request.
* * At maximum continuous current and maximum ambient temperature. Hold
voltage must be maintained within the limits specified to keep contacts closed
and to prevent coil overheating.
* * * Do not use a free wheeling diode or capacitor across the coil.
