Grounding
NEC, article 250 governs grounding method.
Grounding method must follow local electric codes.
Use bolt, M4, cup washer, grounding wires, flat
washer, tooth washer, screw nut, M4 and install as
shown in the diagram below. Torque specification is 2
to 3 Nm. Grounding materials is evaluated under
UL1703.
Maintenance
ASTDNApanelsare designedto require little to no
maintenance.Dependingon local conditions,panels
mayneedperiodiccleaningto removedirt build-upand
soiling. Panelsshouldbe washedwith water to remove
dirt and soiling. Frequencyof cleaning will dependon
localweather conditionsand paneltilt. Onceayear,

General Information
Slope should be less than 5 in/ft (127 mm/305mm)
required to maintain a fire class rating. Any roof
penetration required to mount the module must be
properly sealed to prevent leaks. The modules are rated
fire class C, and are suitable for mounting over class A
roof.
Pole Mount
When installing a module on a pole, choose a pole and
module mounting structure that will withstand
anticipated winds for the area.
Modules installed with mounting holes
Modules should be bolted with M8 and M6 to the
support structures through mounting holes located in
the frame in the back flanges. See table in the following
page. Torque should be 12.5-18 Nm for tightening the
M8 bolt, the torque should be 9-15 Nm for tightening
the M6 bolt.
Modules installed with clamping
Modules should be bolted to the support structures rail
by metal clamps. It is recommended to use clamp under
the following conditions or approved by system
installation. Clamping distance is quarter of the module
length. See table in the following page.
Clamps materials: Aluminum, Bolt torque : 12.5 –18
NM, clamp must not contact the front glass, bolt: M8
SS, flat washer: diameter 16-8.4 mm H1.6 ss, spring
