The following illustrations show the Master Control Relay wired in a grounded
system.
Note The illustrations only show output cir cuits with MCR pr otection. In most
applications input cir cuits do not r equire MCR pr otection; however , if you need to
r emove power fr om all field devices, you must include MCR contacts in series with
input power wiring.
