Mounting Details
Using the mounting diagram Fig. 2a and 2b choose whether wall, array structure or stand
mounting will be used. Be sure to allow NEC clearance for access to combiner. The units can
be mounted side-to-side if multiple combiners are being used.
It is recommended to use galvanized grade 5 or better bolts or stainless steel bolts. The correct
bolt size is 5/16” or 3/8” (or 8-10mm) diameter, SS or galvanized steel hardware is
recommended. Be sure to use flat washers and lock washers. If wall mounting is used, be sure
to verify sheer and pullout strength of anchors or other wall attachments.
WARNING:
Injury could occur if the combiner mounting fails and the unit falls on a
person.
NOTE:
Always use all 4 mounting tabs for mounting.
NOTE:
The 40 lb. weight of the combiner will exert as much as 20 lbs. per bolt on
the 4 wall mounts. Make sure an appropriate safety margin is used for both shear
and tension of wall mounting bolts, anchors or other attachments.
NOTE:
Do not leave enclosure door open when you are not actually working on
the inside the combiner.
