Installation

Installation Guidelines
• Please determine the remote cable route throughout the home or vehicle/boat, both to and from the inverter before connecting any wires.
• Always check for existing electrical, plumbing, or other areas of potential damage before drilling or cutting into walls to mount the remote.
• Make sure all wires have a smooth bend radius and do not become kinked.
• Please ensure the conductors passing through walls, bulkheads, or other structural members are protected. This minimizes insulation damage such as chafing, which can be caused by vibration or constant rubbing when installing this remote in a boat, RV, or truck.
Installation Overview
The remote is required in order to connect the inverter/charger. Each inverter/charger must be connected directly to the remote using the supplied RJ11 communication cables. The remote must be located close to the inverter/chargers within 25 meters and acts as the system control panel.
Mounting the Inverter
• Select an appropriate location to install the remote.
• Mount the remote base to the wall using the 4 screws provided. Please refer to Fig. 1
