MOUNTING THE DATA LOGGER
Location Requirements
■ The DL-300 has an IP20 rated enclosure, which means it must be installed indoors.
■ The RS485 cable is about 4’ long, so the data logger should be mounted no more than 3 feet away from the inverter.
■ The data logger requires an internet connection, be it wired, WiFi or cellular.
■ The data logger can be mounted to the wall, or elsewhere with the use of the din rail and din rail mounts.
Step 1. If the data logger cannot be secured to a stud in the wall, insert drywall anchors prior to installation.
Step 2. Place the data logger against the wall and secure with two screws.
