Installation of cable trays

A. Preparation for assembly

Before starting the installation of troughs, make sure that you have:

· 100x35mm vertical cable trays for cable routing from the roof

· 150x35mm horizontal troughs for cable routing between panels

· Wood screws 4x30mm for fixing troughs

· Yellow green cable LGY 16mm² for grounding

· Solar return cable to make a loop

B. Running troughs on the roof

Start by installing a vertical cable tray on the far left side of your planned installation. The vertical trough must:

· Be on the opposite side of the first eTile module installed

· Be mounted over the entire length of the cover with a gap of about 300mm from the top and bottom

· To be bolted to the counter-lath with screws at a spacing of 150-200mm

Next, mount the horizontal troughs:

· Install them every fourth patch, under the places where the junction boxes of the panels will be located

· Screw to the counter-lath with 4x30mm screws at a distance of 150-200mm

· Leave about 200mm clearance from the far right side

C. Connections and grounding

All troughs must be electrically connected to each other:

· Connect horizontal troughs to vertical ground wire

· In the places where the troughs connect, use connectors that ensure electrical continuity

· Connect 16mm² ground cable to each trough

· Lead the ground wire out of the field along with the solar wires

D. Assembly checklist

Before finishing, check:

· Fixing stability of all troughs

· Correct spacing between fixing screws

· Electrical continuity between all troughs

· No sharp edges that can damage wires

· The correctness of the execution of grounding connections

· Preparation of the route for the return cable

Remember: The robust construction of the trough system is the basis of a safe eTile installation. Do not try to save on the number of screws or the quality of connections.
