2.3.4 Installing the rack
• Select the location for the device so that the connection to the source is as short as possible.
• Leave sufcient space behind the equipment, minimum 30 cm, for ventilation of warm air that
will be exhausted even with devices which feed back up to 90% of the consumed energy.
A device in a 19” housing will usually be mounted on suitable rails and installed in 19” racks or cabinets. The depth
of the device and its weight must be taken into account. The handles on the front are for sliding in and out of the
cabinet. Slots on the front plate are provided for xing the device (xing screws not included).
Acceptable and unacceptable installation positions:
Standing surface
2.3.5 Installing load modules
Before installing any number of load modules the rst time or before removing modules or changing the congura-
tion, notice following:
• Always switch off the rack with the power switch and if possible, remove mains cord
• Remove voltage sources from DC input of all load modules about to be inserted/removed
• In case the rack was operating shortly before it has been switched off in order to insert/remove
modules, wait at least 30 seconds before proceeding to the next action
• Never insert any module while the rack is switched on! If you are not sure whether the indica-
tion on the power switch is right, disconnect mains cord.
2.3.5.1 Inserting modules
The modules are intended to be inserted from left to right, because one module is the guide for next one. With this
intention in mind, the modules could be numbered with position 1 (left) to 5 (right). When going to install a module
in position 4 while the one for position 3 is not yet installed, it will be more difcult to nd the correct position. But
the installation is possible anyway.
Proceed as follows:
1. Insert the module at the desired position and push it into the rack so that it stands out for approx. 2 cm. Upper
or lower row, as desired.
2. Push the module to the left, until it nds stop at the rack guidance (position 1) or the module to the left.
3. Push the module into the rack until full stop. You should notice a short tactile resistance before it nally rests.
4. Fix the module on the front plate with four of the included screws (M2.5x8, metric thread).
5. Continue the same way with further modules, if required.
