Observe the following points when disposing of rechargeable batteries:
▪Separate and sort the individual components of the packaging and dispose of
them accordingly.
▪Observe the generally applicable disposal directives and battery legislation (such
as the German Battery Act (BattG), etc.).
▪Rechargeable batteries must not be thrown in with the general household waste,
but instead in a dedicated collecting bin.
1.2 Preparing the control unit
1. Disconnect the control unit from the power supply.
2. Undo the 6 hexagon socket head cap screws on the surface of the control unit
and open the housing.
1.2.1 Mounting the vent
NOTE
Control units manufactured before week six of 2014 ("2014w06") or that have a
serial number starting with "S- …" do not have an integrated ventilation facility.
Before the rechargeable battery retrofit kit is fitted, the ventilation facility supplied
(cable gland with flexible tube) must be installed.
1. Select a pre-stamped knockout for the M16 cable gland on the rear wall of the
housing and break it out using a suitable tool.
2. Screw in the cable gland incl. flexible tube and tighten hand-tight.
3. Loosely twist, or tie the flexible tube according to the figure below.

5. Carefully press on the printed circuit board until the lock engages.
6. Connect the leads to the ACCU/+X03- terminal.
7. Connect the leads to the poles of the rechargeable battery. Ensure correct
polarity.
1.4 Making ready for operation
NOTE
Carry out a functional test to verify the integrity of the signalling/message functions
during a power failure. The rechargeable batteries are sufficiently pre-charged to
function test the control unit.
1. Mount the housing cover and tighten it hand-tight using the 6 hexagon socket
head cap screws.
2. Connect the power supply.
3. Disconnect the control unit from the power supply and carry out a function test
in battery mode.
ðIf the display extinguishes, open the control unit and verify the correct
position of the charge controller and connections. Correct if necessary.
(ðSection1.3,Page5)
ðWhen the control unit visually and acoustically signals a power failure, the
function test is complete.
4. Connect the power supply.
