5.2.2. Modem / Battery 

1. 

Caution

: Electrolyte inside. Risk of health hazards associated with electrolyte 

leakage. Do not disassemble, puncture, modify, drop, throw, or cause other 
unnecessary shocks to batteries.  

2. 

Caution

: High current if shorted. Risk of injury by high current. Do not short circuit the 

batteries.  

3. 

Caution: 

The batteries might be hot. Risk of burns by hot surface. Do not touch the 

batteries before they have sufficiently cooled down. 
  

Do not put the batteries to the garbage but dispose of them properly according local 
and/or regional regulations. 

Notice: 

Currently, the battery condition is only detected at shutdown, by making sure the battery 
has enough charge to allow a complete shutdown process. If the battery is dead, 
missing, or not able to hold a charge lasting more than a minute or two (the time for a 
normal shutdown, which could be up to 10 minutes), this will be noticed by the software 
at the next power up and an alarm raised. However, this means a “good” battery 
condition can also only be detected at shutdown. If a bad battery is replaced with a good 
battery in the field, the alarm will not be cleared immediately at the next bootup. Instead 
the system will have to have a normal power shutdown and then the alarm will be cleared 
at the following bootup. So, the procedure for replacing a failed battery should be: 

1. Shutdown 

the 

system. 

2.  Replace the battery. 
3.  Power up (alarm will still be raised). 
4. Shutdown 

the 

system. 

5.  Power up (alarm will now be cleared). 

If this is not done, the alarm will be only cleared after the next shutdown and power up 
event of the system. 

Also, observe that an alarm is raised once the battery disconnect 

button on the UI1 board is pressed and the unit is powered up again. To delete the false 
alarm, the unit has to be shut down and powered up again. During the shutdown, the 
battery disconnect button must not be pressed. 
 

Notice:

 For the replacement procedure, also observe the warnings in chapters 

5.1

 and 

5.2.1

. 

Notice:

 For tightening 

SMA connectors, always 
use an appropriate torque 
wrench: 

 

Modem and battery are located on a carrier plate located behind the combiner carrier 
plate. Thus, for replacing the modem or the battery, the combiner has to be removed 
first. To do so refer to chapter 

5.2.1

, observing the corresponding warning messages.
