5.1 Mechanical 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 shock loads.
♦ Make sure the mounting is able to support the weight:
This is particularly important in conjunction with external
battery units (special accessories).
♦ Set up the units so that adequate air circulation is
assured. There must be at least 100 mm clearance at the
back 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.
♦ Set up external battery units (special accessories) to the
side of the UPS system. To ensure the greatest possible
mechanical stability, you should not set up the external
battery unit(s) above or below the UPS system.
♦ Avoid extreme temperatures! We recommend an ambient
temperature of 15 °C to 25 °C in order to maximise 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 4.2, page 20 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, leave the unit to acclimatise for 2 hours before
you switch it on.
