1. Place split lock, then flat washers on the bolts.
2. Insert the bolts through the holes in the frame mounting pads and into the threaded
holes in the robot base mounting pads.
If using through-bolts, insert the bolts through the holes in both the mounting pads and
through the threaded holes in the robot base mounting pads into nuts.
3. Tighten the mounting hardware to the specifications listed in the table above to com-
plete this procedure.
Installing iX4-650HS/800HS Mounting Hardware
iX4-650HS/800HS robots require special considerations for USDA compliance. USDA requires
that all exposed screws be sealed with a gasket, which must be compressed to specific stand-
ards. To achieve this, the iX4-650HS/800HS robot mounting bolts use a spacer that fits inside a
compressible sealing gasket.
The robot base-mounting tabs have spring-lock HeliCoils in the M16 holes, so a lock washer is
not needed on the M16 mounting bolts.
To achieve the correct compression of the sealing gaskets, the mounting tabs on the frame
must be 12.7 mm, +1.3, -0.7 mm thick.
Additional Information: If you choose to use a different frame pad thickness
and provide your own mounting bolts, the bolts need to be M16-2.0, 316 stain-
less steel flange bolt (DIN 6921 standard). The threads must engage at least 24
mm of the robot base threads (HeliCoil), for sufficient support. The bolts must
not bottom out, or the washer seals and gaskets will not be compressed enough
to form a good seal.
The following bolt specifications are required for the iX4-650HS/800HS.

IMPORTANT: Check the tightness of the mounting bolts one week after
initial installation, and then recheck every 6 months. For periodic main-
tenance, refer to Periodic Maintenance Schedule on page 115.
