• Protect the units from external environmental influences (particularly moisture
and dust). Please pay special attention to the information in chapter 3, starting
on page 16 of this manual.
• If the device is taken from a cold room and brought into a warm room or if the
room temperature suddenly drops, condensation may occur within the device.
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 in the lower third of the rack, taking into account the center
of gravity of the rack and making sure that there is adequate fresh air supply.
Universal mounting rail systems are included. The amount of space required for
the 6 kVA UPS is 3U and 5U for the 10 kVA. External battery extension units each
require, directly under the UPS, a further 3U.
1. Firstly install the depth variable enclosed rack rails. Tighten the mounting screws
on the left and right rails, leaving the rail loosely fastened. Roughly adjust the
depth of the rail in the installation location in the rack.
2. Locate the rack mounting positions appropriately and use each two cage nuts
on each spar corresponding to the position of the rack rails. Each rack rail
requires 4 cage nuts. Ensure that there is sufficient space below each UPS for
further addition of battery extension units allowing for a height of 3U. Now
insert the rack rails and attach them to the front and rear of each spar with
two screws. Securely tighten all screws. Please do not forget about the screws
inserted in step 1.
3. Carefully lift the UPS unit and place it on a secure flat surface.
4. Now fasten the two brackets that come with the device to the side of the UPS
and, if using, an external battery unit according to Fig. 4. Make sure to put the
bracket marked “L” on the left and the one marked “R” on the right hand side.
Next, above the rack rails fastening on the cabinet front posts attach a further
cage nut for final mounting of the UPS unit on the mounting brackets.
