Chapter 2: Installation
Installing the Compact I/O
Installing the Compact I/O
The Compact I/O is designed to be mobile with two lifting handles mounted on the front of the chassis. All plug-in
connectors are located on the front panel, with power connectors at the rear. When installing, please leave
enough room for the cables.
Temperature and Cooling
The unit is convection cooled and therefore is ideal for installation within noise critical environments. Proper
operation can only be guaranteed at an ambient temperature between 10°C and 35°C and a relative humidity
between 15% and 85% (not condensing).
Warning
Take care that no devices or cables obstruct the flow of air thereby hindering cooling.
Power
The Compact I/O is delivered with dual redundant power supply units (PSUs); the load is shared between the two
supplies.
Warning
All devices MUST be connected to the mains using the three-cord power leads supplied with the system.
When running with two mains supplies (PSU 1 and PSU 2), make sure that both circuits lie on the same
ground potential. Otherwise, an internal bridge of two ground wires will lead to a ground loop!
