Mounting systems – Installation requirements
The DSC2P rack formats are dedicated to be mounted inside a rack case system.
Warning:
The rack case with the controllers and the power supply has the following electrical
safety degree: IP 20 (according to EN 60529 standard). To respect this degree, each
empty slot (if a controller is not present in the rack case) must be closed by a front
panel. The rack case must be in an enclosure respecting a pollution degree of 2 (refer
to UL 508C and EN 50178 standards for more information).
The rack formats are mounted vertically inside a rack case. Here is an example:
In the solution outlined above, seven DSC2Pxx1-xxx are powered by a DSO-PWS (ETEL's power supply).
The rack case systems should be protected against any splashes of liquid and any contacts with smoke and
dust. It must be installed inside a closed cabinet and screwed on a metallic plate, connected to the ground,
where no vibration will occur.
Fresh air is necessary to cool the controllers inside the rack case (the flow depends on the user application). It
is recommended to install fans in the cabinet to guarantee an air flow (the fan power depends on the user
application).
Caution: some fans may perturb the current measurement of the controller if they are too
close to the rack case. If this problem occurs, use another type of fan or increase the distance between
the fan and the rack case while ensuring the air flow mentioned hereafter.
The air flow inside ETEL's rack
cases with fans is equal to minimum 2 m/s (400 LFM) (the fans, used with the rack case, have an air flow of
94.2 CFM). Refer to the
'DSO-RAC2 Hardware Manual'
for more information about the rack case.
