Types of AC Strain Reliefs
The PDI inverter includes knockouts for use with a standard 3/8" trade size strain relief. Use of a strain relief is required when hard wiring
your inverter. Neglecting to use a strain relief may cause undue stress and fatigue to the wiring connections on your unit. PDI lists examples
of some commonly utilized types of strain relief. Strain reliefs are not provided with purchase of the inverter, and must be provided by in-
staller at the time of installation.
The type of 3/8" trade size strain relief used is ultimately at the discretion of the installer. PDI can only recommend
types of strain relief for end use, and is not responsible for any misuse or absence of strain relief at installation.
