Some strike locks and maglocks have built-in arc
suppression. Consult the installation information
for the locks you are using. It is recommended
that the MOV’s (supplied with the EAC-M90) are
connected across any inductive local to the load.
NB: The supplied MOV’s are only suitable for 12V
applications.
Terminal blocks easily
