SAFETY, INSTALLATION AND OPERATION MANUAL

AVANCIS POWERMAX

PHOTOVOLTAIC MODULES

Fire Safety

• Follow the local guidelines, codes and

requirements for fire safety.

• The installation of a PV system on a

build ing may affect fire safety of the
building.

• For roof application, the PV system

must be mounted over a fire-resistant
roof covering rated for the application
(outside USA and Canada).

• Do not install or use PowerMax

mod-

ules near hazardous locations where
flam mable gases or vapors can be gen-
erated or collected.

• PowerMax

modules mounted on

build ings will most likely continue to
produce hazardous DC voltage in case
of a fire, even in the following cases:
• low-light intensity
• disconnected line between PV mod-

ules and inverter

• partly or entirely damaged modules
• damaged DC cabling

• Stay away from the PV sytem during

and after a fire.

• Inform the fire fighters about the par-

ticular hazards from the PV system.

• After the fire, have your installer bring the

PV system in a safe mode (if possible).

Mechanical Installation

• Depending on the installation, appro-

priate measures should be taken to pre-
vent any accumulation of water, dirt
and other substances.

• Landscape and portrait mounting of the

modules in different directions is allowed.
All modules should be mounted in one
direction to achieve a unique appealing
surface. This means that the module la-
bels on the backsides are pointing to the
same side and that the cables are at the
other side of the modules.

• PowerMax

modules must be securely

fastened using support frames or
mount ing kits suitable for PV applica-
tions and designed for local maximum
wind and snow loads. Follow the in-
structions from the applicable suppliers.

• Ensure PowerMax

modules are not

subjected to wind or snow loads in ex-
cess of the maximum permissible loads
as specified on the applicable Power-
Max

Product Information literature.

• When necessary, fix two - four hooks per

Power Max

module at the mounting

area in the back rail in order to prevent
the glass sliding down. The end of these
hooks should go around the glass edge
without touching the metal. When
allowed, alternative measures may be
used as well.

• Ensure PowerMax

modules are not sub-

jected to excessive forces due to ther-
mal expansion of the support structure.

• During installation and operation, the

support structure must not cause exces-
sive bending or twisting of the Power-
Max

module.

• Provide adequate rear ventilation under

a PowerMax

module for cooling and

dissipation of condensation or moisture.

• Clearance of 2 cm/0.78 inches or more

between PowerMax

modules is required

to allow for thermal expansion of the
PowerMax

modules in case of frontside

mounting. For backside mounting a
smaller minimum module distance of
0.5 cm/0.2 inches is given to improve
array performance.

• Always keep the back surface or any

other part of the PowerMax

module

free from any foreign objects or struc-
tural elements which could come into
contact with the module and damage it.

• Do not drill any additional holes in the

back rails, and do not increase the di-
ameter of pre-drilled holes. Doing so
could compromise the mechanical inte -
g rity of the PowerMax

module and/or

cause electrical hazards or corrosion.

• AVANCIS requires that its PowerMax

modules are mounted using the four
mounting areas locat ed on the back rails
(also see the drawings on the right):

Electrical Installation

• PV modules of different configurations

and different nominal power ratings
must not be used in the same PV array,
unless the inverters are specified for this.

• PowerMax

modules are factory-equipped

with electrical cables and connectors for
easy interconnection in series.

• Use identical LC4 connectors for connec -

ting the PV modules, or, in case connectors
of different manufacturers are to be paired,
the connection should be approved in
writing by both manufacturers.

• User-supplied electrical cable extensions

might be required for connecting the
PowerMax

modules.

• Use applicable system wiring with suitable

cross-sectional areas and connectors
that are approved for use at the limiting
reverse current (I

) of the PowerMax

module.

• Match the polarities of electrical cables

and terminals when making the con-
nections; failure to do so may result in
damage to the PowerMax

module.

• Make sure that the PV system has ap-

propiate lightning and over-voltage pro-
tection and follow any applicable regu-
lations (including those from insurance
companies).

• Ensure that all electrical connections are

secure and tight.

• A bypass-diode is integrated in one of

the two PowerMax

module junction

boxes. This diode is not user-replace-
able. The junction box must not be
opened in the field.

• The maximum number of PowerMax

modules being connected in series must
be calculated in line with the applicable
regulations in such a way that the speci -
fied maximum system voltage (V

sys

) of

the PowerMax

module and all other

electrical DC components will not be
exceeded in open-circuit operation.

• Not more than two PowerMax

mod-

ules or module strings should be con-
nected in parallel without using appro-
priate string current protection (other-
wise the maximum I

specification can

be exceeded and damage the module).

Underwriters Laboratory Information for
USA and Canada:

• Under normal conditions, PowerMax

modules are likely to experience con-
ditions that produce more current
and/or voltage than reported at Stan-
dard Test Conditions. Accordingly, the
values of I

and V

marked on this

module should be multiplied by a factor
of 1.25 resp. 1.10 when determining
component voltage ratings, conduc-
tor capacities, fuse sizes and size of
controls connected to the PV output.

• Refer to section 690-8 of the National

Electric Code (NEC) for an additional
multiplying factor of 125 % (80 %
derating) which may be applicable.
