CAUTION:
I. Wtien tatding relays are instailed in equipment, tha latch and reset coil shoud net be powered simullaneously. Coil shoiid not be
pulse wfth Iess than tha nommai coil voftage and pulse width shodd be a minimum df three times, the specified operate time of the
relay. If these condition are not followed, it is possible for the relay to in be the magneticdlyneutral position .
2. Swftdwg voftage is for test purpose only and are no to to used design criteria.
