Remark: Illustrations of the three different methods for clamping modules onto the frame with aluminum clamps.
Each aluminum mounting clamp comes with an M8 bolt, a plain washer, a spring washer, and an M8 nut. To fasten the module:
1. Place the module on the two supporting bars (not provided). The bars should be made with stainless material or
treated with an anti-corrosion process (e.g., anodic oxidation treatment).
2. The bar’s top surface contacted with module frame should come with grooves compatible with an M8 bolt.
3. If the bars do not come with grooves, holes of a suitable diameter may need to be drilled to allow bolts to be attached to
the bars at the same locations as mentioned before.
4. Secure each clamp by attaching plain washer, spring washer, and nut, in that order.
5. Both of close-ups of Fig. (g) indicate the middle clamps and Fig. (h) indicate the side clamps for your reference. The
dimensions for the middle clamps are a ≥ 40 mm, b ≥ 26 mm, c = 8 mm, d ≥ 28 mm, and Ø = 9 mm. The torque for
tightening the nut and bolts recommended 28Nm when the property class of bolts and screws is Class 8.8.
6. Especially for Fig. (d) mounting method, slide bolts through groove on the supporting bars next to the locations where
the 4 clamps are to be fastened. The module may be clamped only in the permitted clamping are as on the long edge of
the frame. For exact locations on the frame refer to Fig. (i) in conjunction with table 1 below.
