Installation Notes

Installation should be performed by a qualified electrician or industrial controls technician in accordance with applicable NEC requirements. De-energize and lock out the control panel before removing or installing any contact block. Confirm the contact configuration (NC) matches the circuit logic requirements before completing the installation. Do not force-fit the block onto an incompatible push button body, as improper seating can result in unreliable contact engagement.
