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.
