Mounting Rail Attachment:

Mountingrailscannowbeattached

totheanglebrackets.Todothis,

simplyinserttheT-Boltontheangle

bracketintotheC-Channelontheside

ofthemountingrail.TurntheT-Bolt

clockwiseuntilitstops(approximately

¼turn).See Figure 2.1(Torque:

6to8ft.lbs)

ToensurethatT-Boltisproperlyalignedmake

surethatthelineonthebackoftheT-Boltis

perpendiculartotherailandispointingstraightup

anddown.See Figure 2.2

Continuefasteningallangle

bracketsonmountingrailsuntil

thesystemiscompletelyattached

totheroof.Seenextstepifarails

needtobejoinedtogether.

Additionalmountingrailscanbe

attachedusingasplice.Toinstall,

simplyinsertthespliceintothe

endoftherailthatwillneedto

bejoineduntiltherivetonthe

middleofthesplicestopsthe

insertion.Thenslidetheopposingrailovertheexposedendofthespliceand

pushtogether.Donotattempttothrough-boltsplice.½”gaporseparation

betweenrailsisrequiredforthermalexpansion.See Figure 2.4

Telescope and Anti Slip Hardware Installation:

Optional:

Tobestadaptthelength

ofthemountingrailsto

themoduledimensions,

usethepre-assembled

telescopicshaftfrom

WürthCanada.Toinstall,

slidetheshaftontothe

mountingrailandfastenittotheroof

hooks.Adjustthelength(max.23

inches).See Figure 3.1

Now,slidethelockingclipontothe

mountingrailandtightenthescrew.

See Figure 3.2(Torque:6to8ft.

lbs.)

Beforetheyaremounted,themodulesareequippedwithanti-slipprotection.

Thisisdonebyattaching¼x¾in.SSbolts(withtheshankdownward)with

¼in.nutsinthelowermountingholesofthemodule.Whenmountinglarge

modules(e.g.ASE250),5/16x¾in.SSboltsareused.See Figure 3.3

Toinstalltherstmodule,placetheanti-slipscrewonthetopsideofthetop

mountingrail.Thiswillallowthemoduletorestonthemountingrailswithout

Assembling and Installing the Footings:

Sigma posts must be fixed in the ground in accordance

with local soil conditions and structural drawings. The

length of sigma posts can vary.

This depends on local conditions and is determined by

the geotechnical engineer conducting the soil survey.

End of sigma post with 2 mounting holes must protrude

from ground to a height of 20 in. (500 mm). Holes on

sigma post must be facing front and back of PV array. It

does not matter whether the open side of the sigma

post is facing to the right or the left as long as every

post is facing the same direction. Spray galvanizing

should be used on any part of the sigma post where the

galvanizing has been disturbed during installation.

If a concrete foundation is prepared, the sinking of the

sigma posts with rebar requires a reinforced

foundation. A hole must be drilled within 8 inches of the

bottom of the sigma post and painted with spray

galvanizing for corrosion protection. Rebar must then

be inserted halfway through hole and set into concrete

footing at required depth to resist pullout reaction.

Bearing block must now be attached to the aluminum

vertical post with supplied M8 x 85 mm socket head cap

screws, nuts and washers using predrilled hole in

vertical post and bearing block. Flat side of bearing

block must face thin side of vertical post profile to

maintain structural Integrity.

See Figures 3.1 and 3.2

Nut and washer must be fastened on the thick side of

the vertical post extrusion.

See Figure 3.2

strap installation.)

The previously assembled bearing block and vertical

post assembly from step 3 are inserted into the sigma

posts with the short vertical posts serving as the front

array.

The posts are aligned on site in accordance with the tilt

angle of the rack; a minimum lapped joint length of

approximately 12 in. (200 mm) is needed for

sliding head of the T-bolts into the two slots on the

bottom of the base rails (ST-AK 182-120)on the north-

After the frame is complete the system must be fixed to

the sigma post with the supplied M10 x 120mm

hardware. The vertical posts can be moved up and

down to achieve the required tilt angle. When the

correct angle is achieved a cordless drill with a 7/16 bit

must be used to drill through the existing holes in the

sigma post and through the aluminum vertical post

before the hardware can be installed. Again, the

vertical post must contact the sigma post for a

minimum of 12 in. (200 mm).

(Torque: 10 ft. lbs.)

After the system rails are attached to the bearing

blocks, the upper module rails are attached

lengthwise. This requires 4 cross adapters per

Click the cross adapters onto the base rails and slide

attachment lip into channel on base rail. Fasten the

clamp screws by turning clockwise.

See Figures 6.1 & 6.2

rivet on splice stops forward movement

Next, slide the other system rail onto the splice. Push

complete and add cross adapter if applicable. Splice

does not have to occur at a cross rail. Splice is now

properly installed and will allow the rail to perform
