rear vent for ventilation purposes. Do not block the vents on
the front. Make sure that there is a free space of at least 50
mm in the front.
• Place any external battery units directly underneath the UPS
system. To ensure maximum mechanical stability, place
each tray in its own rack mount.
• Avoid extreme temperatures! An environmental temperature
of 15°C to 25°C is recommended to maximize battery life. Do
not expose the units to direct sunlight or operate them close
to any other heat sources, e.g. radiators.
• Protect the units from environmental influences (particularly
moisture and dust). Please pay special attention to the
information in Chapter 3, starting on pg. 17 of this manual.
• Using an external manual bypass is recommended; this
makes it possible to disconnect and remove the UPS for
servicing, for example, at any time.
If the device is taken from a cold room and brought into a warm
room or if the room temperature suddenly drops, condensation
inside the device may occur. To prevent any condensation
buildup, let the device acclimatize for 2 hours before you switch it
on.
Installation in a 19" rack
Mount the trays preferably in the lower third of the rack, taking
into account the center of gravity of the rack and making sure
there is adequate fresh air. Universal mount systems are
included. Each tray requires 2U (~88mm).
1. First install the enclosed rack rails, which can be varied in
terms of depth, see Fig.1. Insert the screws in the left and
right rail loosely.
Roughly adjust the depth of the rail in the installation location
in the rack.
