4.3Point of Installation
Note the following points when setting up the UPS system and its external battery units (special accessories):
♦The contact surface must be smooth and in 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) on 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 22 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.
