AVANCIS POWERMAX
SAFETY, INSTALLATION AND OPERATION MANUAL
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
ules near hazardous locations where
flam mable gases or vapors can be gen-
erated or collected.
• PowerMax
®
modules mounted on build -
ings will 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 water, dirt or other substances
from accumulating on the module.
• 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. Keep the tilt angle of the
modules between 0° and 40° against the
horizontal when mounting the modules
in landscape orientation (does not apply
to free-field installations).
• PowerMax
®
modules must be securely
fastened to a mounting structure which
follows the local building law regula-
tions and which is suitable for PV appli-
cations and the local maximum wind
and snow loads. Follow the instructions
of the respective supplier.
• Ensure that PowerMax
not subjected to wind or snow loads in
excess of the maximum permissible
loads as specified on the applicable
PowerMax
®
Product Information litera-
ture.
• Ensure that PowerMax® modules are
not subjected to excessive forces due to
thermal expansion of the support
structure.

PHOTOVOLTAIC MODULES
• During installation and operation, the
support structure must not cause exces-
sive bending or twisting of the Power-
®
Max
module. All four mounting points
must be within the same plane. To min-
imize mechanical stress on the mod-
ules, the maximum deviation of each of
the four mounting points from the
plane shall be less than 1 mm.
• Provide adequate rear ventilation under
a PowerMax
®
mod-
dissipation of condensation or moisture.
• When mounted, clearance of a mini-
mum of 5 mm between PowerMax
modules is required to allow for thermal
expansion of the modules.
• With the exception of the back rails, all
other parts of the PowerMax
must always be kept free from any
structural elements that can come into
contact with the module and cause
damage.
• Do not drill any additional holes in the
back rails. Doing so could compromise
the mechanical inte g rity of the Power-
Max
®
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.
• The modules' glass edges are sensitive
to impact. Avoid contact with other
modules, tools, etc.
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
with electrical cables and connectors
for easy interconnection in series.
• Use identical LC4 connectors for
connec ting the PV modules. In case
connectors of different manufacturers
are to be paired, the connection should
be approved in writing by both manu-
facturers.
• User-supplied electrical cable extensions
might be required for connecting the
PowerMax
• Use applicable system wiring with
suitable cross-sectional areas and
connectors that are approved for the

• Match the polarities of electrical cables
and terminals when making the con-
nections; failure to do so may result in
damage to the PowerMax
• 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.
• 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
the PowerMax
®
module and all other
electrical DC components will not be
exceeded in open-circuit operation,
even at low temperatures. If there are n
modules, the following must apply:

sys
• Not more than two PowerMax
or module strings should be connected
in parallel without using appropriate
string current protection (otherwise the
maximum I
specification may be ex-
r
ceeded and the module will be dam-
aged).
Underwriters Laboratory Information for
USA and Canada:
• Refer to section 690-8 of the National
Electric Code (NEC) for an additional
multiplying factor of 125 % which
may be applicable.
• 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
sc
oc
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.
