INSTALLATION - PV MODULES
40
MODULE MOUNTING PROCEDURE
1. Mid clamps and end clamps can be
inserted into the rail by following the
procedure shown, making sure the
spring washer is correctly in place.
For easy use of Z-modules, ensure
Allen head bolt threads do not project
through lower side of Z-module, so the
Z-module is free to move along the
rail.
2. In positions where earthing plates are
required, slide the earthing plate over
threaded section of Allen head bolt
and press earthing plate into rail so
that rail retention tabs hold the
earthing plate in position.
3. Install PV module under end clamps.
Ensure end clamps are tight against
the module and are at least 25 mm
from the rail ends. For end clamps with
earthing plates, ensure the frame of
the module is located on top of the
protrusions of the earthing plate.
Tighten end clamp bolts to 21 Nm.
4. Place a mid clamp with Z-module and
Allen head bolt in each rail and slide
into position. Ensure that the mid
clamp is tight against the module. For
mid clamps with earthing plates,
ensure the frame of the module is
located on top of the protrusions of the
earthing plate. Fasten loosely (approx
2 – 3 turns).
5. Place the next module onto the rail
and slide the module into the mid
clamps. In positions where earthing
plates are required, ensure both
module frame edges are located on
top of the protrusions of the earthing
plate
6. Tighten each mid clamp Allen head
bolt to 21 Nm.
Repeat steps 4 to 6 for each remaining
module in the row.
