•
Attach a separate conductor as grounding wire to the 4mm
diameter grounding holes with a set of M4 bolt, cup
washer, flat washer, lock-toothed washer, spring washer and
nut.
•
Exposed copper of the grounding wire shall not contacts the
module frame in case of corroding the frame.
5) Wiring
For the wiring, pay attention to:
•
To minimize the risk of indirect lighting strike, avoid forming
closed loops when designing the system. Check that wiring
is correct before starting the generator. If the measured open
circuit voltage (Uoc)［and short-circuit current［(Isc) different
from the specifications, there may be a wiring fault.
•
Jetion modules use the J-Box, on the backside of the module,
is weatherproof and is designed to be used with standard
wiring or conduit connections. Wiring methods should be in
accordance to the NEC (National Electrical Code). Bypass
diodes and cable clamps are included with each module when
shipped from the factory.
•
Use modules of the same configurations in the same system.
When connected in series, all modules must have the same
current. When connected in parallel, the modules must all have
the same voltage. The quantity of modules connected should
match the voltage specifications of the devices used in the
system. The modules must not be connected together to
create a voltage which is higher than the permitted system
voltage. When designing the Jetion system, please always
take into consideration the variation of the voltage under
different temperatures (please check the respective tempera-
ture coefficients of the modules, the Voc of the modules will be
rise when the temperature drops).
•
The number of modules in series and in parallel in a system.
•
While connecting the modules in series, the total voltage
should be less than the maximum system voltage Umax［(IEC:［
Umax=1000V;［UL:［Umax=600V).
•
While connecting the modules in parallel, the total current
should be less than the maximum system current.
6) Maintenance and Cleaning
•
Do not change the PV components optionally (diode, junction
box, plug connectors).
•
Given a sufficient tilt (at least 15°C), it is not generally neces-
sary to clean the modules (rainfall will have a self-cleaning
effect). In case of heavy soiling (which will result in output
reductions), we recommend cleaning the modules using
plenty of water (from a hose) with mild detergent and using
a gentle cleaning implement (a sponge).
CAUTION［DON’T
USE DETERGENTS CONSISTING OF ABRASIVE, ACETONE
OR OTHER CORROSIVE ELEMENTS.
Do not clean the
modules with cold water during the warmer hours of the day
in order to avoid creating any thermal shock that maybe
damage the module.
Dirt must never be scraped or rubbed away when
dry, as this will cause micro-scratches. We recommend that
the system is being inspected at regular intervals.
7) Checklists
•
All fastenings are tight and secure and free of corrosion.
•
All cable connections are secure, tight, clean and free of
corrosion.
•
Cables are not damaged in any way.
•
Checking the earthing resistively of metals.
8) Warning
•
The maximum load on the module must not exceed 30 lb/ft²
(146.5 kg/m²). To avoid exceeding the maximum load, site-
specific live loads such as wind and snow should take into
account.
•
We recommend that the maximum number of modules in
parallel should be no more than 2. When more than two
modules or strings are planned to be put in parallel, use string
fuses. The number of modules in series has to be made
according to the max system voltage of the inverter which is
being used. However the Voc Voltage of all modules in series
should never exceed more than 1000V.
•
The plug connector has its own polarity. Make sure that the
connection is safe and tight. Ensure that they are in good
electrical and mechanical condition.
•
The plug connector should not receive external stress.
•
Do not attempt to drill holes in the glass surface of the
modules.
•
Do not drill additional mounting holes in the frame of the
modules.
•
Do not hoist the module through the J-Box or cable.
•
Never use a module with broken glass or torn substrate.
Broken modules cannot be repaired and contact with any
module surface or frame can lead to electrical shock.
•
Do not install or handle modules when they are wet or during
the period of high wind.
•
Keep children well away from the system while transporting
and installing mechanical and electrical components.
•
Do not strike or physically damage the module.
•
Avoid cutting and damaging the frame and the frontside or
backside surface of the module during handling and installati-
on.
•
Do not stand or step on the module.
•
Do not put extra objects on the module in case of glass
broken.
•
The J-Box must be on the higher side of the module when it is
mounted.
