4 INSTALLATION
4.1 RACK MOUNTING
When mounting the P
ULSAR
units, use 19 inch racks, preferably those with a depth of at least 70 cm.
The units should be mounted adequately, so as to secure optimal operation and reliability of your unit.
Use sliders compatible with the 19 inch racks used to support the P
ULSAR
properly.
When mounting more than one unit, we advise you to leave a space of at least one unit in between.
These spaces can be covered afterwards with ventilation profiles. Mounting other units together with
the P
ULSAR
obviously requires the air flow to be able to reach all units.
Additional components, such as combiners and netstrips are preferable to be mounted at the back of
the racks, so that the free air flow between the sides of the unit and the rack is not restricted.
At the bottom and the top of the rack, ventilation profiles should be mounted so as to allow the fresh
air to enter and the hot air to leave the rack. It is of great importance to place the racks in a condi-
tioned room with a constant temperature of about 25 °C.
When mounting five or more units on top of one another , the use of fans is necessary. The power of
the fan depends on the number of units mounted. For a rack containing 15 units with a free space of
one unit between the units, an airflow of 300 m³/hour is required. Mounting the fans requires taking
into account that the air should blow alongside the units and that it can enter the rack through the
lower ventilation profiles.
4.2 POWER CONNECTION
Before any other connection is made, the unit must be connected to a protected earth terminal in both
of the following ways (EMC requirements):
- Via the protected earth terminal.
- Via the three-wire power cable.
Failure to ground the unit properly can result in personal injury.
Do not defeat the earth-grounding protection by using an extension cable,
power cable or autotransformer without a protective ground conductor.
Before connecting the unit to the mains of the building installation, the proper functioning of the
protective earth lead of the building installation needs to be verified.
Check if your AC power source voltage corresponds to the appropriate power input voltage for the
apparatus. This voltage is noted on the rear side.
To change the mains fuse, disconnect the power cable. Pull up the cap and replace the fuse by a new
one.
The use of repaired (jumpered) fuses and/or the short circuiting of the fuse
holders is prohibited.
