Overview of the Required Cables

Overview

The properties of the required cables are listed in the table below. Use pre-assembled cables to reduce the risk of wiring errors. Pre-assembled cables can be found in section Accessories and Spare Parts. If the product is used to comply with the requirements as per UL 508C, the conditions specified in section Conditions for UL 508C and CSA must be met.
