♦ 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 16 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.
