INSTALLATION INSTRUCTIONS -PHOTOVOLTAIC MODULES-
1. INSTALLATION
Mounting Using Clips:
The PV modules can be mounted with clips (clamps) as defined in the
following. Note that the mounting clips should meet the required dimensions
as defined in the Figure1. Note that the CLIP CENTER POSITION (e) from
the module corner should be located in the range as specified in the Annex.
All clips shall hold the module frame completely within their width. Please be
aware that the module under heavy load would get serious deflection which
could cause cell cracks that affects power degradation. The PV module must
be supported on the array system and must overlap the array rail by at least
10mm.
Mounting Using Frame Bolt Holes:
The modules may be fastened to a support using the bolt holes in the bottom
of the frames at any of locations shown in Annex. The module should be
fastened with four (4) M8 bolts. Recommended torque is 12.5 Nm.
2. ELECTRICAL INSTALLATION INSTRUCTION
Cable characteristics
Conductor size: 4.0mm
2
, Cable type: XLPE cable (H1Z2Z2-K)
Maximum DC voltage: 1.5kV
Ambient temperature: -40°C to +90°C
Maximum conductor temperature: 120 °C
PV module configuration (Recommend)
# Maximum series configuration: please refer to Table 1
# Maximum parallel configuration: (Parallel connection of each
string shall be conducted with following two options. Any other
parallel connections are prohibited.)
a) Case of using the diodes; 1 diode per maximum 2 parallel
strings (Connect a diode or more in series for every string or
every 2 parallel strings for protection of PV module from
reverse current over load.)
b) Case of using the fuses; 1 fuse per every string (Connect a
fuse for every single string for protection of PV module from
reverse current over load.)
Connection cables requirement
The PV module shall be mated to the same connectors;
Type: MC4 （System voltage 1,000V）
Brand: Staubli Electrical Connectors
In case connectors will be replaced by qualified personnel
according the mounting instructions of the manufacturer of the
new connectors, the guarantees on the module itself, will remain
valid according the applicable terms.
3. WARNING
Keep all PV MODULES and electriacal CONNECTORS clean &
dry before installation.
4. Disposal
Dispose PV modules properly. For
Information about the proper
disposal, contact your local
recycling site.

* The maximum series number of modules depends on the local conditions. These values are calculated under the condition of Voc at -40 °C.
Under normal conditions, a PV module is likely to experience conditions that produce more current and/or voltage than reported
at Standard Test Conditions. Accordingly, the values of Isc and Voc marked on this PV module should be multiplied by a factor
of 1.25 when determining component voltage ratings, conductor capacities, fuse sizes and size of controls connected to the PV
module output.
The PV module has been qualified in an environmental temperature range of -40 °C to +40 °C and up to 100% relative humidity
as well as rain, and the altitude up to 2,000m in accordance with IEC61730.
Class for protection against electric shock
This PV module is classified as “Class Ⅱ ” according to
IEC61730. These PV modules are intended for installation
where geeral user access and contact to insulated live parts is
anticipated.
FIRE RATING
This PV module is rated as “Fire safety class C” according to
IEC61730-2:2004 or UL790.
