4.3 Set-Up
Note the following points when setting up the UPS system
and its external battery units (special accessories):
♦ The contact surface must be smooth and level. It must
also be sufficiently strong and sturdy to avoid vibration
and shocks.
♦ Make sure that the mounting is able to support the
weight, especially in conjunction with external battery
units (special accessories).
♦ Set up the units so that adequate air circulation is
assured. There must be at least 200 mm clearance
behind the rear fans for ventilation purposes. Do not
block the intake openings on the front and, if present,
on the side of the unit. There must be a gap of at least
50 mm here.
♦ External battery units must be placed on the side of the
UPS system. To ensure the greatest possible
mechanical stability, do not place the external battery
unit(s) above or below the UPS system.
♦ Avoid extreme temperatures! We recommend an
ambient temperature from 15°C to 25°C in order to
maximize the service life of the batteries. Do not
expose the units to direct sunlight or operate them
close to other heat sources such as radiators.
♦ Protect the units against external effects (in particular
moisture and dust). In this regard, please also refer to
the instructions in chapter 3, page 15 in these operating
instructions.
If you transport the unit from a cold room into a warm one, or
if the room temperature suddenly drops, then condensation
may form inside the unit. To avoid any damage due to
condensation, let the unit acclimate for 2 hours before you
switch it on.
