KSU Installation
2.2.7 External backup batteries installation
In case of power failure, the external backup batteries automatically maintain uninterrupted power for the IP LDK-20
system. The external batteries must provide 24 Volts DC. This is generally accomplished by connecting two 12 Volt
batteries in a series arrangement.
Figure 2.2.7 External Back Up Battery Installation
※ Note : The cable for connecting the battery is supplied with the KSU.
Operation of the batteries is controlled by the MBUB. This IP LDK-20 MBUB will provide charging current to the
batteries during normal AC power operation at a maximum of about 100mA. During battery operation, the battery
operation of MBUB will be stopped if the AC power re-applied or the battery voltage is too low to maintain full-system
operation.
The external batteries can maintain system operation as needed depending on several elements such as, battery
charge status, condition and capacity of the batteries, and system configuration (number of station ports).
CAUTION
•
•
It is recommended to use a fuse (5A @250V) between battery and system.
Recommended battery capacity is 24V/10AH MF battery; the IP LDK-20 system should operate more than 3
hours with batteries that are in good condition.
•
Carefully check the battery polarity with cable colors (RED and BLUE) when connecting the battery to the
system.
•
•
Make sure that you do not short-out the external backup batteries or cables.
There is a danger of explosion if external backup batteries are incorrectly replaced. Replace only with the
same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the
manufacturer’s instructions.

4.4 External backup batteries connection
In case of power failure, the external backup batteries automatically maintain uninterrupted power for the IP LDK-20
system. The external batteries must provide 24 Volts DC. This is generally accomplished by connecting two 12 Volt
batteries in a series arrangement.
Figure 4.4 External Back Up Battery Installation
※ Note : The cable for connecting the battery is supplied with an expansion module.
Backup batteries for the basic KSU are used in parallel with an expansion module.
The IP LDK-20 MBUB will provide charging current to the batteries during normal AC power operation at a maximum
of about 100mA. During battery operation, the battery operation of MBUB and an Expansion Module will be stopped if
the AC power re-applied or the battery voltage is too low to maintain full-system operation.
The external batteries can maintain system operation as needed depending on several elements such as, battery
charge status, condition and capacity of the batteries, and system configuration (number of station ports).
CAUTION
•
•
•
There is not the battery charging circuit in an expansion module.
It is recommended to use a fuse (5A @250V) between battery and system.
Recommended battery capacity is 24V/10AH MF battery; the IP LDK-20 system should operate more than 3
hours with batteries that are in good condition.
•
Carefully check the battery polarity with cable colors (RED and BLUE) when connecting the battery to the
system.
•
•
Make sure that you do not short-out the external backup batteries or cables.
There is a danger of explosion if external backup batteries are incorrectly replaced. Replace only with the
same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the
manufacturer’s instructions.
