CORRECT WIRING SCHEME
· Ensure that the wiring is correct before starting up the
system. If the measured open circuit voltage (Voc) and
short-circuit current (Isc) differ from the specifications,
this indicates that there is a wiring fault.
CORRECT CONNECTION OF PLUG CONNECTORS
· Make sure that connections are safe and tight.
Plug connector should not be subjected to stress
from the exterior. Connectors should only be
used to connect the circuit. They should never
be used to turn the circuit on and off.
USE OF SUITABLE MATERIALS
· Only use dedicated solar cable and suitable plugs
(wiring should be sheathed in a sunlight-resistant
conduit or, if exposed, should itself be sunlight-
resistant) that meet local fire, building and electrical
regulations. Please ensure that all wiring is in
perfect electrical and mechanical condition.
· Installers may only use 2.5-10 mm
single conductor cable listed and labeled as PV Wire
or TUV 2PfG1169 approved, that is 90°C wet rated
with proper insulation that is able to withstand the
maximum possible system open-circuit voltage.
Only copper conductor material should be used.
Select a suitable conductor gauge to minimize
voltage drop and ensure that the conductor
ampacity complies with local regulations (i.e. NEC
690.8(D)).
CABLE PROTECTION
· Secure the cables to the mounting system using
UV-resistant cable ties. Protect exposed cables
from damage by taking appropriate precautions
(e.g. placing them inside a plastic conduit). Avoid
exposure to direct sunlight.
· A minimum bending radius of 60 mm is required
when securing the junction box cables to the
racking system.
CONNECTOR PROTECTION
· Protect exposed connectors from weathering

damage by taking appropriate precautions.
Avoid exposure to direct sunlight.

MODULE GROUNDING

· EQUIPMENT GROUNDING: double glass modules
do not present any exposed conductive parts, and
therefore do not require to be electrically groun-
ded for compliance to the National Electrical Code.
· Proper equipment grounding is still required for
the racking system in compliance with all local
electrical codes and regulations. Please refer to the
racking system user instructions.
