Enclosure Interlocks
When an industrial control panel controls industrial machinery, and operates with a voltage more than 50 V AC / 60 V DC, each door of the control panel must be locked so that the door can only be opened when the disconnecting means is switched off. Door interlocking can either be mechanical or electrical, and must meet the following conditions. The interlocking must be activated automatically when closing the doors without additional measures. It must be possible for an authorize person to defeat the interlock with a tool so that the door can be opened for maintenance and service, with the main switch staying on.
Hoffman PROLINE G2 Mechanical Interlocks utilize a ½ inch aluminum hex rod, which feeds through door actuators positioned at the top of the enclosure. The door-mounted activator brackets engage with the actuators, and the combination of the actuators and a hook and capture system, increases the safety by preventing system re-energization without closure of all secondary doors and the primary door.

Hoffman P2AMIB PROLINE G2 Mechanical Interlock The Mechanical Interlock solution and associated components have been redesigned to simplify installation and increase operator safety. The solution is based around a ½-in. (13 mm) Aluminum Hex Rod, which feeds through door actuators positioned only at the top of the enclosure(s). The door-mounted activator brackets engage with the actuator(s), also installed in series is a hook and capture system: the combination of actuator and hook increases safety by preventing system re-energization without closure of all secondary doors and the primary door. The components can be combined to safely interlock any number of enclosure configurations, including applications where a rear door or series of doors are present. Note that interlock components will work with all door options (solid single, overlapping double, window, and disconnect), mounting on the upper door bar near the center to provide maximum security. Consult installation instructions to determine which components would be required to safely interlock a defined solution.
