The VCM-3 shall be mounted on a vertical metal plate, either directly or on a low profile DIN rail.
2.
There shall be at least 70mm to other devices or sides of the cabinet on the TOP, BOTTOM and FRONT
of the VCM-3.
3.
There shall be at least 20 mm to other devices or sides of the cabinet on the LEFT and RIGHT of the
VCM-3.
4.
The metal plate on which the VCM-3 is mounted (either directly or on a low profile DIN rail) shall not
exceed the maximum ambient temperature rating of the VCM-3.
DIN Rail Mounting
When the VCM-3 is fitted on a 35 mm mounting rail (DIN EN 50 022)
