with Dow Corning 340 or equivalent grease and then screw the adapter into the
mounting surface. The grease is required to ensure good coupling between the
adapter and the mounting surface at high frequencies. A light oil may also be
used.
Step 5: This step only required for accelerometers with a serial number not
preceded by the letter "G". Use a torque wrench with a 1" hex socket. Tighten the
adapter to the mounting surface with a torque of 6.8 ± 1.4 N•m (60 ± 12 inAlb). To
remove the adapter, apply a counterclockwise torque to its hex base.
Step 6: Lightly grease the accelerometer mating surface with Dow Corning 340
or equivalent grease and then screw the accelerometer into the mounting
surface. The grease is required to ensure good coupling between the
accelerometer and the mounting surface at high frequencies. A light oil may also
be used.
Step 7: Use a torque wrench with a 15/16" hex socket. Tighten the accelerometer
to the mounting surface with a torque of 3.3 ± 0.56 N.m (30 ± 5 in-lb). To remove
the accelerometer, apply a counterclockwise torque to its hex base.
2.2.3 Routing Cable
When installing the interconnect cable, route it away from the moving
components of the machine and avoid small bending radii. To minimize noise,
avoid routing cables near or in the same conduit, raceway, or cable tray with
power lines. Prevent the cable from bending sharply, twisting, knotting, or
straining. Route the cable through the conduit to prevent physical damage. If the
cable must be routed inside lubrication oil lines, be sure it will not be subjected to
temperatures exceeding its specified operating range.
2.2.4 Routing Conduit
To route cable through the conduit, connect one end of the conduit to the
protective enclosure or other structure in which the monitor is mounted. Connect
the other end of the conduit rigidly to a structure near the accelerometer. Before
pulling cable through the conduit, protect the terminal lugs by wrapping the cable
with tape or a similar covering. Be sure that the cable does not rub against rough
or sharp surfaces.
2.2.5 Routing Armored Cable
Use armored cable if the cable is not routed inside conduit. Secure the cable to
the supporting surfaces with clips or similar devices. Connect one end of the
armor directly to the enclosure or other structure in which the monitor is
mounted. Connect the other end of the armor rigidly to a structure near the
330400 and the 330425 Accelerometer. The recommended minimum bend
radius for armored cable is 38.1 mm (1.5 in).
