* The pull-in / drop-out voltage and coil resistance will change at the rate of 0.4% per degrees C.
** Reclosure of the Form B may occur if the max. voltage is exceeded. Coil polarity on Form B must be observed. Pin two is positive.
*** Coil polarity must be observed. Applying a 2 ms pulse to coil number one with nominal voltage will latch the contacts.
Applying a 2 ms pulse to coil number two will unlatch the contacts.
