Installation
Mounting
The VCM can be mounted using the mounting holes located on the feet of the enclosure. Mounting holes on
the feet of the device are 0.22 inches (5.6 mm) in diameter, and can accommodate a #10 or M5 machine screw.
Tighten the screws to wrench tight.
Grounding
The VCM must be grounded while in operation. This unit can be grounded either through the surface to which
it is mounted (in the event that the VCM is mounted to a grounded plate), or a grounding wire attached to the
ground lug on the side of the VCM. The ground lug is a #10-32 thread and can accommodate a #10 ring lug
connector. The grounding wire should be at least 12 AWG wire. The total resistance between the VCM and
ground should be less than 1 Ω.
Air Supply Quality
The supply air must be filtered to ensure that particles larger than 40 μm have been removed. The air can be
lubricated or unlubricated.
