Secure the Base of the Mast
To secure the base of the mast:
1. Use the base of the mast as a template to drill holes through the mounting surface.
2. Loosely secure the Mast System to the mounting surface with four ½ inch (M12) sets of
customer-provided stainless steel hardware. Use heavy-duty, extra-thick (MS 15795-
819) stainless steel flat washers. Do not torque the hardware at this point. This will be
done later in these procedures. The mounting hardware must include a proper means to
resist vibration loosening such as thread-locking compound and/or locking hardware.
Finalize Physical Installation of the Mast
Equipment Damage – Cutting! Wear gloves when installing the electrical ground strap to avoid
possible injury.
With the mast loosely secured at the Support Bracket Assembly and at the base of the mast:
1. Ensure the mast is level in all directions. If necessary, shims may be added to correct
the alignment of the mast. It is necessary to check the mast in two places 90° apart
when leveling.
2. Torque all hardware as appropriate for its size and grade to secure the mast in place
against the support structure and mounting surface. Ensure the mast remains level as it
is torqued. Recommended torque values for stainless steel fasteners are as follows:
M10:
3/8-16:
½-13 & ½-20: 450-530 in.-lb. (51-60 N-m)
M12:
Use manufacturer's specified torque values for other fastener materials/grades.
3. Attach one end of the Ground Strap to the mast at any of the Ground Stud locations. The
M5 Ground Stud provided can be moved to any of the Ground Stud locations as needed.
The Ground Stud locations are designated with the electrical ground label (Figure 2-6).
Torque to 24-31 in.-lb. (2.7-3.5 N-m).
