Notes: 1.When latching relays are installed in equipment, coil should not be pulsed with less than the nominal coil voltage and pulse width should be a minimum of three times the specified operate time of the relay. If these conditions are not followed, it is possible for the relay to in be the magnetically neutral position.
2.Do not apply voltage to the coil for a long period (more than 1 minute).
