Risk of electric shock. Risk of fire and injury from electric arc.
| Do not disconnect connections under load.
| Ensure sufficient protection against contact with live parts.
| Only use insulated tools.
| Do not insert any electrically conducting parts into the connectors.
| Never open the junction box.
| Make sure there is no tension in the cable when positioning and heed the specified minimum bend radius.
| Avoid large conductor loops.
Installation shall be in accordance with CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical
Code, Part 1.
3.3.3 Parallel and serial connection
Solar modules of the same type can be connected in parallel. These solar modules are fundamentally designed for
series connection.
Material damage due to connection errors.
| Only use solar modules of the same type and output for parallel connection. Take measures for overcurrent
protection (e.g. line fuse) if necessary. Never exceed the specified maximum series fuse rating of the solar
modules.
| Make sure that only solar modules with the same amperage (Impp) are connected in series and make sure that
the string voltages are the same. Even at low temperatures, never exceed the maximum permissible system
voltage of the solar modules.
| Make sure that the number and connection of the solar modules match the electrical values specified by the
devices connected to the photovoltaic system.
| Use only 90ºC wet-rated, sunlight resistant, stranded or solid conductor cables for all modules and interconnect
wiring that may be exposed to weather.
| Make sure that the polarity is correct.
3.3.4 Connecting the photovoltaic module
On the rear of the solar module, there is a connection box with the connection cables, the plug and the socket.
Connection cable length
1000mm
Connection cable cross section
4mm
²
Allowable ambient temperature range for cables
from -40°C
to +85°C
All Details for wiring should be in accordance with the NEC guidelines, and the grounding method of the frame of
arrays shall comply with the NEC, article 250.
3.3.5 Grounding
Equipment grounding requirements must be checked in accordance with the applicable regulations and standards
before work is started. The module frame or array must be grounded to avoid the hazards of electric shock or fire.
The position of possible grounding connections can be found in Fig. 3-1.
The grounding wire can be mounted on one of the designated holes in the module frame (see Fig. 3–1).
Avoid contact corrosion when using different metals and observe electro-chemical insulation ratings.
An equipment grounding conductor can be fixed to the holes in the frame. Copper ground wire or equivalent to be
used: #12 AWG.
Observe the applicable regulations.
