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 batter y is supp lied 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 batter y is supp lied with an expan sion mo dule.
Backup batteries for the basic KSU a re 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.

SECTION 6. STARTING THE IPLDK-20 SYSTEM
6.1 Before Starting the IP LDK-20 System
The DIP switch (SW1) of Memory Backup Battery should be turned ON before installing the MBUB, to protect system
data in the case of a power failure. To prepare for preprogramming, perform the following Steps:
1. Set the DIP switch (SW3) on the MBUB to ON.
To initialize all the data in Admin Programming, the 4th pole of SW3 should be set to ON.
Plug the AC power cord into the IP LDK-20 System and AC outlet.
Program the Country Code as applicable.
Reset the IP LDK-20 System.
Set the 4th pole of SW3 on the MBUB to OFF when the system operates normally. The 4th pole of SW3 is set to OFF,
to protect the various features addressed by Admin Programming after system power-up and initialization.
6.2 Basic Preprogramming
The IP LDK-20 System can be programmed to meet an individual customer's need. There are two ways to perform
ADMIN Programming:
- PC ADMIN : Refer to the PC ADMIN Programming Manual.
- DKTU : In this manual we explain DKTU (Station 10) in ADMIN Programming.
6.2.1 DKTU (Station 10) programming
All programming is done at Station 10 (Station port # 00) using the LDP-7024D digital key telephone.
Additional programming stations may be assigned (PGM 113 – FLEX 1), but only 1 DKTU can be active in the
programming mode at any one time.
When in programming mode, Station 10 does not operate as a normal telephone, but instead works as a
programming instrument with all of the buttons redefined. The keys of the dial pad are used to enter the various data
fields and to enter numerical information:
- Flexible Buttons
The 24 buttons located at the top of the phone are used to indicate a specific data field and to enter information.
- SPEED Button and * Key
Are sometimes used to delete data or to indicate the end of data input.
- REDIAL Button
Could be used to delete one digit or character from the end of entered digits or characters.
