Electrical Installation; Installation - Jinergy JNMP60 series Installation Manual

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. f indicate the middle clamps and Fig. g indicate the side clamps for
your reference. The dimensions for the middle clamps are a ≥ 40mm, b ≥ 26mm, c = 8mm, d ≥
28mm, and Ø = 9mm. The torque for tightening the nut and bolts recommended 28Nm when the
property class of bolts and nuts is Class 8.8.

6. Especially for Fig. c 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 area as on the long edge of the frame. For exact locations on the frame
refer to Fig. h in conjunction with Table 3 below.

Electrical Installation

Details for wiring in accordance with the NEC, and that the grounding method of the frame of
arrays shall comply with the NEC, Article 250. CNL model instruction manuals shall also incl-
ude a statement that installation shall be in accordance with CSA C22.1, Safety Standard for
Electrical Installations, Canadian Electrical Code, Part 1.

Installation

4.1.1 The electrical characteristics are within ±10 percent of the indicated values of Isc、Voc
and Pmax under standard test conditions (irradiance of 1000mW/cm, AM 1.5 spectrum, and
a cell temperature of 25°C (77°F)).
4.1.2 The maximum system voltage for all module series is 1000V for North American Market
and 1000V for European Market.
4.1.3 Connect quantity of modules that match the voltage specifications of the inverters used
in system. Commended number of 60pcs module is 20 in series and 1 in parallel, 72pcs
module is 17 in series and 1 in parallel. Modules must not be connected together to create a
voltage higher than the permitted maximum system voltage under the worst local temperature
conditions.
4.1.4 Under normal conditions, a photovoltaic module is likely to experience conditions that
produce more current and/or voltage than reported at standard test conditions. The requirem-
