CABLE AND CONNECTOR PROTECTION
•
Secure the cables to the mounting system
using UV-resistant cable ties. Protect exposed
cables from damage by taking appropriate pre-
cautions (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.
•
Do not place connectors in locations where wa-
ter could easily accumulate.
5.2
GROUNDING
•
For grounding requirements in North America, a
module with exposed conductive parts is consi-
dered to comply with UL 1703 only when it is
electrically grounded in accordance with both
the instructions presented below and the re-
quirements of the National Electrical Code. Any
grounding means used with EDF ENR PWT mo-
dules should be NRTL certifi ed to UL 467 and
UL 2703 standards. Please consult our technical
service team for the formal approval process.
•
For grounding requirements in other areas,
although the modules are certifi ed to Safety
Class II, we recommend them to be grounded
and that module installation should comply
with all applicable local electrical codes and
regulations.
•
Grounding connections should be installed by
a qualifi ed electrician.
•
Connect module frames together using
adequate grounding cables: we recommend
using 4-14 mm² (AWG 6-12) copper wire. Holes
provided for this purpose are identifi ed with
a grounding symbol
(IEC 61730-1). All
conductive connection junctions must be
firmly fixed.
• Do not drill any extra ground holes for conve-
nience this will void the modules warranty.
• All bolts, nuts, fl at washers, lock washers and
other relevant hardware should be made of
stainless steel, unless otherwise specifi ed.
• EDF ENR PWT does not provide grounding hard-
ware.
• One grounding method is recommended for
EDF ENR PWT standard modules, as descri-
bed below. For alternative grounding methods,
please refer to Annex B (Alternative Grounding
Methods) of this installation manual. It may not
be possible to use standard grounding me-
thods for certain module ranges. Please refer to
Annex B for more details.
