Assemble the Z bracket, and make
sure that the Z bracket is adjustable.

Check to make sure the wires are securely tightened to the correct terminal block
Check that the power supply is connected and operating properly
Make sure the lock switch is wired correctly
Make sure the lock switch is wired correctly.
Make sure the electromagnet and armature plate are properly aligned
Make sure the contact surfaces of the electromagnet and armature plate are clean
and free from dust
Ensure the electromagnetic lock is set for the correct voltage.
Check for proper voltage at the electromagnetic locks input. If low, determine if the
correct wire gauge is being used to prevent excessive voltage drop.
Remove any diode installed across the magnet for "spike"
suppression. (The magnet is fitted with a metal oxide varistor to prevent back EMF)
Check the installation of armature with supplied template.
