ZS COMP INSTALLATION MANUAL FOR COMPOSITION SHINGLE ROOFS - U.S.
1.2 General Safety Precautions
Follow all instructions in this manual and the PV module installation manual. The installer is ulti-
mately responsible for ensuring that all installations are performed in compliance with applicable
codes and standards, as well as industry best practices.
1.2.1 Installation Safety
•
The installation process requires working on sloped and elevated building surfaces, in out-
door weather conditions, using tools and heavy components designed for the generation of
electricity.
-
Use properly anchored fall protection equipment.
-
Use caution to prevent objects from falling or dropping off the roof area.
-
Cordon off ground areas directly beneath the roof work area when possible.
•
Always use personal protection equipment such as safety glasses, gloves, etc. as neces-
sary.
•
Do not perform installations in excessively wet, windy, or inclement weather conditions.
•
When working in hot weather, work crews should take care to prevent symptoms of over-
heating or deyhdration.
•
Use proper lifting and carrying techniques when handling heavy components at the job
site. If conditions are challenging for moving PV modules to the roof area, use a mechani-
cal lift.
•
Follow best practices when working around high-voltage electrical equipment.
•
Do not anchor fall protection equipment to roof mounts, or any other inappropriate roof
structure.
•
The installer is responsible for:
-
Following all applicable regional and local codes, standards, and regulations
-
Ensuring that all personnel are properly trained, equipped, and licensed
-
Obtaining all required permits and inspections
-
Verifying that the roof structure can support the array under live load conditions.
-
Verifying that the system is installed over a properly rated fire-resistant roof covering
•
Ensure that Zep Solar components are properly engaged with the PV modules.
•
Do not subject the PV modules to excessive loads or deformation such as twisting or
bending.
1.2.2 Electrical Specifications
