AXITEC INSTALLATION
– USA 170727
A qualified, licensed professional must do all wiring.
Wiring should be protected to help ensure personal safety and to prevent its damage.
All modules connected in series should be of the same model number and/or type.
Suitable measures will be required to protect against overcurrent (e.g. line fuses) for parallel connection
of modules. Care must be taken to avoid exceeding the given load with regard to the IR reverse current,
see datasheet of module.

MODULE WIRING
The maximum system voltage is 1000 V DC according to UL standards.
The maximum number of series connected modules depends on system design, the type of inverter
used and environmental conditions.
These modules contain factory installed bypass diodes. If these modules are incorrectly connected to
each other, the bypass diodes, cable, or junction box may be damaged.
For field connections, use minimum No. 12 AWG copper wires insulated for a minimum of 90°C.
The size, type, and temperature rating of the conductors to be used; Size: 12AWG; Type: Tinned fine
copper strands, according to VDE 0295/IEC60228, class 5; Temperature rating: -40°C up to +125°C
4.3
ARRAY WIRING
Use copper wire only (Cu only) that is sunlight resistant and is insulated to withstand the maximum
possible system open circuit voltage.
For use with non-metallic wiring systems only.
For field connections, use minimum No. 12 AWG copper wires insulated for a minimum of 90°C
The size, type, and temperature rating of the conductors to be used; Size: 12AWG; Type: Tinned fine
copper strands, according to VDE 0295/IEC60228, class 5; Temperature rating: -40°C up to +125°C
The minimum and maximum cable diameters: min. 12 AWG (4mm²), max. 10AWG (6mm²)
Check local codes for requirements.

JUNCTION BOX AND TERMINATION
Modules equipped with one junction box contain terminals for both positive and negative polarity, and
bypass diodes.
One terminal is dedicated to each polarity, with the polarity symbols engraved onto the body of the
junction box.
To ensure reliable electric connection and to prevent possible intrusion of humidity, the connectors have
to be mated and locked together until a click can be heard.
