To remove a battery:
1. Make sure that your product settings allow you to open the cover without
starting the tamper alarm.
2. Switch off the mains power, if necessary, and remove the cover.
3. Disconnect the battery. Note that depending on the battery model the connec-
tors may be located differently.
4. Remove the battery from the holder.
Dispose of the battery as required by local ordinances or regulations.
See the specifications for your product or contact technical support for
information on replacement batteries.
Battery fitment
The battery leads supply high currents to the board during fault conditions. Poor
connections lead to excessive voltage drop and can affect system performance.
At the board connection, the installer must ensure that:
•
Terminal wiring is performed with the battery disconnected.
•
The bare wire ends are neatly dressed and fully inserted into the terminal
housing. Less than 2 mm of exposed wire should be visible after termination.
•
The complete bundle of wire strands is inserted into the screw terminal. No
broken strands should be visible.
•
There are no free strands outside of the metal block in the terminal housing.
•
The retaining screw is correctly torqued.
•
On completion, the polarity is verified at the board (red to positive, black to
negative) prior to battery connection.
At the battery connection, the installer must ensure that:
•
The positive lead (red) is the first wire connected and the last wire
disconnected.
•
The battery terminal polarity and open terminal voltage is validated prior to a
connection being made.
•
The battery tab and receptacle mate firmly and completely. It should not be
possible to remove the terminal with gentle force.
•
If a custom battery terminal is in use, the checks in the prior section regarding
wire dress, strand damage and connection firmness are appropriately applied.
New batteries must be clearly marked with the date of installation in order to
facilitate future maintenance activities. When batteries are replaced, the board
should be queried using the control software to validate the newly installed units.
When making voltage measurements at the battery terminals to establish battery
state, healthy batteries that have not been discharged in the preceding 48hrs
should measure >13.5 V
