Minimum Air Clearances
The 890 gives off heat in normal operation. The mounting surface for the unit should be normally cool.
Allow a free flow of air through the top and bottom ventilation slots and heatsink. Remember that any other
equipment may have its own clearance requirements. If you mount next to each other, the clearances should
be added to produce an overall clearance value.
890CS : Cubicle-Mount
(Europe: IP2x, USA/Canada: Open Type).
890CS units are designed for mounting side-by-side as shown. A minimum of 150mm (6") free-air space
must be allowed at the top and bottom of each unit.
