Installation Notes

De-energize the circuit and confirm power is off at the panel before handling any plug or receptacle. The plug lock is applied after the plug is fully seated in the receptacle to maintain a secure mechanical connection. Do not force the lock onto a plug that is not fully engaged in its mated receptacle.
