HAR power cord is provided on CE models. To operate the Powermax85, use a plug that meets national and local
electrical codes. The plug must be connected to the power cord by a licensed electrician.
The procedure is similar to installing a single-phase power cord as shown in the section 2-10 Single‑phase power cord

Extension cord recommendations
Any extension cord must have an appropriate wire size for the cord length and system voltage. Use a cord that meets
national and local codes.
The table on the next page provides the recommended gauge sizes for various lengths and input voltages. The lengths
in the tables are the length of the extension cord only; they do not include the power supply’s power cord.
