draiNagE HolEs
Each corner of the REC panel frame has small drainage holes spaced 55 mm from the corner of the panel frame that allow water caused by rain,
condensation, snow melt, cleaning or any other process to exit the frame easily and minimize damage caused by freezing and thawing (fig. 9). These
holes must not be used for mounting the panel, and they must not be covered by any part of the mounting structure.
To enable effective drainage and ensure there is no damage to the panel, the drainage holes must remain fully open and enable water
egress during and after installation.
The shape and dimensions of the drainage holes may vary slightly from the below image depending on product and/or frame design.
grouNdiNg
Local regulations may require grounding of the panels. Where grounding is necessary or desired, it must be done using an electrical connection
from the panel frame. REC solar panels have a small round grounding hole positioned near each corner of the panel on both the long side and the
short side,
as shown in fig. 9,
to aid in grounding. T
hese can be further
identified by the grounding symbol stamped in the frame next to it on the long
side. The support bars across the rear of REC N-Peak solar panels are connected to the frame via specially designed grounding clips and do not
need to be individually grounded. Check all applicable requirements before beginning installation.
•
Suitable grounding clips, lugs or other constructions must be used,
•
attach grounds to the grounding holes in the panel frames,
•
Follow the grounding device manufacturer’s installation instructions to ensure a safe and conductive connection, including any supplementary
hardware, e.g., star washer, and tighten according to recommended torque.
Where common grounding hardware (nuts, bolts, star washers, split-ring lock washers, flat washers and the like) are used to attach a
grounding device, the attachment must be made in conformance with the grounding device manufacturer’s instructions.
To avoid galvanic corrosion, galvanized or hot dipped zinc plated fasteners are preferred, however stainless steel fastening materials
are equally suitable.
Negative grounding of the panels is not required by REC.
