2.0 Installation

2.1 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.
