Minimum distances for a correct UPS system
cooling.
5.1.5.2. Location for parallel systems.
•
As an example of three equipments in parallel, Fig. 15
shows them with their battery case. For systems with two
equipments in parallel and/or more battery modules pro-
ceed accordingly in the same way.
Likewise, obviate the illustration of the battery modules
when they are not available.
The numbering of the equipments in Fig. 15 doesn't have
any purpose less than number each unit in the illustration.
•
For a correct cooling, the space around equipment must be
free of obstacles. Respect the minimum distances stated in
Tab. 1 from section 1.2.1 of the document EK266*08 (Safety
Instructions), where the figures of each dimension A, B, C
and D are stated according to the power rate of each equip-
ment.
For the battery cases, keep the same distances as the UPS
enclosure.
5.1.5.3. Immobilising the equipment.
•
The equipment has casters with brakes. Once the equip-
ment is placed in its final location, to immobilise the equip-
ment is recommended to lock them.
5.1.5.4. Preliminary considerations, before connecting the
equipment.
•
In the description of this manual, there is reference to con-
nect terminals and manoeuvring switches, which are only
available in some models or equipments with extended
back up times. Ignore those operations related with your
unit in case it does not have them.
•
Regarding the installation instructions of a single equip-
ment or parallel system, follow and respect them.
•
The switchgear or external manual bypass panel:
At least, the installation will have one protection for
the short-circuit in the power supply line of the UPS.
For single equipments, it is recommended to install an
external manual bypass panel, equipped with input,
output and manual bypass protections.
For parallel systems,
it is essential
to install a switch-
gear or manual bypass panel. The switches of the panel
must allow isolating one UPS from the system, in case
of any failure and allow feeding the loads with the rest
ones, either during the preventive maintenance tasks or
during the failure and its reparation.
•
An external manual bypass panel for a single unit or parallel
system can be purchased under request.
Also, it can be manufactured by yourself by keeping in mind
the version and configuration of the available equipment
or system and the attached documentation in the CD-ROM
or el Pen Drive as regards to «Recommended installation
diagram».
•
The documentation delivered together with this us-
er's manual and/or CD-ROM or Pen Drive, includes
information regarding the «Recommended installation dia-
gram» for each input and output configuration. This docu-
mentation shows the wiring circuit diagrams, as well as the
protection and cross cable sizes that are connected to the
equipment, considering the nominal voltage. All the figures
are calculated for a
total maximum cable length of 30 m
between the switchgear panel, equipment and loads.
For longer lengths, correct the cross cable sections in
