Environment
ViX drives operate in a temperature range of 0° to 40°C with natural convection, or 50°C
Max with forced-air cooling (see Hardware Reference), at normal levels of humidity (5-95%
non-condensing). The drives can tolerate atmospheric pollution degree 2, which means only
dry, non-conductive pollution is acceptable.
Drive Cooling
Cooling of all drive types is by natural convection up to 40°C. To assist cooling, drives
should be installed vertically in an area where there is at least a 50mm (minimum) air gap
above and below the package and a 10mm (minimum) gap either side. Avoid mounting
heat-producing equipment directly below a drive.
Installers must ensure that the air temperature entering the drive or rising up to the drive is
within the ambient temperature restrictions. Under normal use the air temperature leaving
the drive and heatsink may be 25°C above ambient.
In the final installation, check that the ambient temperature specification of 40°C Max
(without forced air cooling) is not exceeded directly below the top-most drives and that any
circulating air flow is not being blocked from reaching the drives. For cabinet cooling
calculations, allow 20W per drive. For DIN rail mounting, see the thermal limitations
statement in Drive Mounting Options.
