Installing the module
Make sure that the installation is carried out
safely:
Protect yourself and other persons from falling, do
not carry out the installation in heavy winds and
eliminate the risk of falling objects as much as pos-
sible . Secure the work area in order to avoid the
endangerment or injury of persons .
Observe the allowable maximum mechanical
loading:
Do not exceed the maximum mechanical loading
and make sure to consider location-specific loads
such as wind or snow . Remember that the mod-
ule might sag when loaded under certain circum-
stances . In order to avoid damaging the module by
pointed or uneven structures, do not place fasten-
ers or cable ties between the rear of the module
and the cross section .
Ensure that the modules are grounded prop-
erly:
Under the terms of Centrosolar AG, grounding
of the module frame (if present) and the mount-
ing rack is not required for fault-free operation .
To reduce the risk of electric shock (e .g . due to
static charge) as far as possible, Centrosolar AG
recommends to ask an experienced installer to
carry out a proper grounding . If an external light-
ning protection system has been already installed,
the PV system has to be integrated in the exist-
ing lightning protection concept by a specialist .
Country-specific standards and regulations must
be observed .
The grounding connections between the modules
must be checked and accepted by a qualified elec
-
trician . Furthermore, the main grounding may only
be connected by a qualified electrician.
In the USA and Canada, a grounding method ap-
proved by Underwriters Laboratories (UL) is oblig-
atory .
To provide proper grounding, an optimal electrical
conductivity is required . For this purpose, ground-
ing holes are provided at the rear of the module
frame (if present) .These grounding holes are
marked by a stamped ground symbol .
Grounding symbol:
Connect the grounding terminal only to the provided and
marked grounding holes at the rear of the module frame.
For grounding we recommend the Solklip ground-
ing terminal with integrated thread-cutting screw,
(UL 467 approved, UL number E69905), manu-
factured by Tyco Electronics . Observe the addi-
tional instructions at
www.tycoelectronics.com
.
These grounding terminals accommodate 4 mm²
(AWG 12) and 6 mm² (AWG 10) stripped solid cop-
per wires . The wires must not be cut, notched or
scratched . No further preparation is required . We
also recommend to use the Tyco Electronics Solar
AWG wire (UL 854) . This wire is tested for outdoor
use .
