Taurus TAU-450W-144M, Installation Manual

MOUNTING INSTRUCTIONS

MOUNTING METHODS

 -PV modules can be mounted to the subst-

ructure using either corrosion-proof M8 bolts 

placed through the mounting holes on the rear 

of the module or specially designed module 

clamps.

 -Regardless of the fixing method the final instal-

lation of the modules must ensure that:

 -A clearance of at least 115mm is provided 

between modules frame and the surface of the 

wall or roof.

 -The minimum distance between two modules 

is 10 mm.

 -The mounting method does not block the mo-

dule drainage holes.

 -Panels are not subjected to wind or snow loads 

exceeding the maximum permissible loads, 

and are not subject to excessive forces due to 

the thermal expansion of the support structu-

res.

MOUNTING WITH BOLTS

 -The frame of each module has 8 x φ9mm 

mounting holes, ideally placed to optimize the 

load handling capability, to secure the modules 

to supporting structure.

 -To maximize mounting longevity, Taurus Reno-

vables Solar strongly recommends the use of 

corrosion proof (stainless steel) fixings

 -Secure the module in each fixing location with 

an M8mm bolt and a flat washer, spring washer 

and nut as shown in Figure 1 and tighten to a 

torque of 16 Nm.

 -Fig. 2

MOUNTING WITH CLAMPS

 -Taurus Renovables Solar has tested its mo-

dules with a number of clamps from different 

manufacturers and recommends the use of 

clamps which have an EPDM or similar insu-

lating washer, fixing bolt of at least M6. The 

clamp must overlap the module frame by at 

least 7mm but no more than 10 mm.

 -Use at minimum 4 clamps to fix modules on the 

mounting rails.

 -Modules clamps should not come into contact 

with the front glass and must not deform the 

frame.

 -Be sure to avoid shadowing effects from the 

module clamps.

 -The module frame is not to be modified under 

any circumstances.

 -When choosing this type of clamp-mounting 

method, use at least four clamps on each 

module, two clamps should be attached on 

each long sides of the module (for portrait 

orientation) and each short sides of the module 

(for landscape orientation). Depending on local 

wind and snow loads, additional clamps may 

be required to ensure that modules can bear 

the load.

 -Applied torque should refer to mechanical 

design standard according to the bolt customer 

is using, ex:M6 is 8N*M;M8 is 16N*M.

 -Fig. 3
 -Other mounting configurations can be used 

however, failure to comply with the above 

recommendations will result in a lowering of 

the load handling (snow/wind load) capabilities 

below the product specification 5400/2400Pa 

and product failure as a result of an overload 

situation will not be covered by the guarantee.

GROUNDING

 -All module frames and mounting racks must be 

properly grounded in accordance with approp-

riate respective National Electrical Code.

 -Proper grounding is achieved by bonding 

the module frame(s) and all metallic structu-

ral members together continuously using a 

suitable grounding conductor. The grounding 

conductor or strap may be copper, copper al-

loy, or any other material acceptable for use as 

an electrical conductor per respective National 

Electrical Codes. The grounding conductor 

must then make a connection to earth using a 

suitable earth ground electrode.

 -Taurus Renovables Solar modules can be 

installed with the use of third party listed 

grounding devices for grounding the metallic 

frames of PV modules. The devices have to 

be installed in accordance with the grounding 

device manufacturer’s specified instructions.

 -Taurus Renovables Solar recommends using 

the following grounding ways

 -Using Schleter for grounding. Connecting mo-

dules to the support structure according to the 

picture below. (Grounding accessories need 

pass the UL467 standard test.)

 -Fig. 4
 -Recommended torque is 20.5Nm
