3.6 Installing Modules
The Liebert APS ships configured from the factory (modules pre-populated) and tested as a system to
your requirements. If you removed any modules to facilitate installation, refer to the following steps to re-
insert them properly.
3.6.1 Installing Power, Battery and Charger Modules
1. With the plastic bezel removed, lift module to appropriate bay, resting end of module on bay
shelf.
NOTE: Do not rest the module on any plastic bezels. It could damage the bezel.
NOTE: Two battery modules must be installed in the same row to complete the battery string.
2. Refering to Figure 3.9 below, slowly push the module until about 1/3 of the module is in the
bay.
3. Lift the module up, then continue pushing until about 5cm (2in.) of the module remains
outside the bay, then push it firmly and smoothly to insure that it is fully inserted.
