Types of AC Strain Reliefs
The PD1600 Series 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 installer at the time of installation.
