The maximum distance between two adjacent module frames should be within 50 mm (1.96 in) for the side with mounting clamps,
and within 25 mm (0.98in) for the side without mounting clamps, in order to meet the system cable scheme.
CORRECT CONNECTION OF CONNECTORS
 Make sure that all connections are safe and properly mated.
The PV connector should not be subject 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.
 Connectors are not waterproof when unmated. When
installing modules, connectors should be connected to
each other as soon as possible or appropriate measures
(like using connector endcaps) should be taken to avoid
moisture and dust penetrating into the connector.
 If end caps are present on un-mated connectors, carefully
remove by hand the end caps before connecting the
connectors. Do not use any sharp tool which may damage
the connector. The use of tools is not needed.
Positive connector endcap

Do not connect different connectors (brand and model)
together.

Do not clean or precondition the connectors using
lubricants or any unauthorized chemical substances.
USE OF SUITABLE MATERIALS
 Only use dedicated solar cable and suitable connectors
(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 single-conductor cable listed and
labeled as PV wire which is 90° C wet rated in North
America, and single conductor cable with a cross section
area of at least 4 mm² (12 AWG), 90° C wet rated in other
areas (i.e. IEC 62930: 2017 approved), with proper
insulation which 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 (e.g. NEC 690.8(D)).
CABLE AND CONNECTOR 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 metallic raceway like EMT conduit). Avoid exposure to
direct sunlight.
 A minimum bending radius of 60 mm (2.36 in) is required
when securing the junction box cables to the racking
system.
 Protect exposed connectors from weathering damage by
taking appropriate precautions. Avoid exposure to direct
sunlight.
 Do not place connectors in locations where water could
easily accumulate.

5.2 GROUNDING

 For grounding requirements in North America, a module
with exposed conductive parts is considered to comply with
UL 61730 only when it is electrically grounded in
accordance with both the instructions presented below and
