1 SUNRAC GENERAL REFERENCES
This installation guide contains important information which should be read and understood
before installation and start-up. For safe and reliable operation, the entirety of this guide should
be considered essential reading as safety and operational information is provided in all sections,
not only in the“safety references”section. Both the installer and person responsible for the on-go-
ing operation should read and understand this guide. This guide should always be available at the
installation site. This installation guide refers to the PV-module mounting system SRTP-PM-X only.
The total PV-module area of the PV-modules must not exceed 91 ft². The maximum width of the
PV-modules, including the distances between the PV-modules must not exceed 205 inches and the
height must not exceed 67 inches with the combined maximum surface area of 91 ft². PV-modules
certied to IEC 61215 or UL 1703 must be installed vertically. If the PV modules are not certied to
IEC 61215, UL 1703 then care should be taken to assess the suitability for mounting onto the sub-
structure of the SRTP-PM-X.
The customer must consider the local weather conditions and the suitability of the SRTP-PM-1-X
to operate in these conditions. The Pole Mount structure is designed to perform with a maximum
wind speed of 80mph. The maximum ice thickness is 1inch at maximum windspeed. Snow thick-
ness equivalence of the ice thickness will vary from 2 inch to 12 inchesdepending on local condi-
tions. Where modules are installed in non-equatorial regions thenthe tilt angle of the modules will
reduce the likelihood of high snow thickness.
ALL WARRANTY CLAIMS AGAINST SUNRAC ARE INVALID IF THE SRTPPMX IS INSTALLED IN
INAPPROPRIATE CONDITIONS.
