Installation Location The installation location for the myPV CommsSafe is easy to locate on the solar site. A concrete pad with a standard unistrut is built on site during initial construction - and is designed to be the installation location for the myPV CommsSafe. - Page 7 The three phase power or 120V power should be terminated in the bottom left of the cabinet. Refer to the Quick Start Guide for more information. All three power supply levels of the myPV CommsSafe are rated for a control panel SCCR level of 10KA.
- Page 8 Whip installation is easy - our whips come pre-terminated; however in the event that they are not or you need to do some troubleshooting, follow these steps. 1. Separate the different wire colors in the whip - to make sure you can see them all in front of you.
- Page 9 Arrival The Customer is responsible for receiving and unloading of all equipment deliveries. The myPV CommsSafe will arrive in a sealed box - and is ready for installation as soon as the package is opened. Whenever possible, your Solar-Ops Account Manager will share tracking information and put the driver directly in contact with the receiving party for receiving coordination.
- Page 10 This guide walks you through every step on how to safely, and securely attach your myPV CommsSafe to the Unistrut utilizing the predrilled feet on the back of the cabinet, install your sensors, and successfully and safely terminate the power. Do not modify the cabinet to mount it or it will no longer be weather proofed.
