DRAINAGE HOLES
On the long and short sides of the REC frame small drainage holes can be found that allow humidity and water to exit the frame easily and minimize
damage (fig. ). These are spaced mm from the corner on /-cell format panels and mm on -cell format panels. 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 aer installation. The shape and dimensions of the
drainage holes may vary depending on product and/or frame design.
GROUNDING
A panel with exposed conductive parts is considered to be in compliance with IEC & UL only when it is electrically grounded in accordance
with the instructions presented below and the requirements of the National Electrical Code. When grounding a panel, it must be done using an electrical
connection from the panel frame. Local regulations may require grounding of the panels. Grounding must be done using an electrical connection from
the panel frame. REC solar panels have a clearly marked, small round Ø mm grounding hole positioned near each corner of the panel on both the long
side and the short side, as shown in fig. and can be further identified by the grounding symbol stamped in the frame next to it. Check all applicable
requirements before beginning installation:
• Suitable grounding lugs must be used: Listed (KDER) ILSCO, GBL-DBT (tin plated) (E),
• Grounding cable size should be between AWG (. mm - . mm),
• Aach grounds to the grounding holes in the panel frames,
• Fix lug to the frame using a star washer (#) and lock nut (#), ensuring a conductive connection,
• 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.

NOTE
• To avoid galvanic corrosion, galvanized or hot dipped zinc plated fasteners are preferred, however stainless steel fastening materials are equally
suitable.
• The support bars across the rear of REC Alpha Series panels are connected to the frame via specially designed grounding clips and do not need
to be individually grounded.
• Negative grounding of the panels is not required by REC.
