The power socket wall outlet should be located near this equipment and be easily accessible.

In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that con-
tains lead.
We will use PbF when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn), Silver, 
(Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair 
work we suggest using the same type of solder. 

• PbF solder has a melting point that is 50

° ~ 70° F, (30° ~ 40°C) higher than Pb solder. Please use a soldering iron with tempera-

ture control and adjust it to 700

° ± 20° F, (370° ± 10°C). 

Exercise care while using higher temperature soldering irons.:
Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB.

• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100

°F, (600°C).

• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the 

opposite side (See figure, below).

There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufac
turer's specific instructions for the melting points of their products and any precautions for using their product with other 
materials. 
The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

When discarding P. C. Board, delete all personal information such as telephone directory and caller list or scrap P. C. Board.

Hybrid IP-PBX needs an optional power supply unit (PSU) suitable for its configuration. Calculate the amount of "load figures" 
from the type and number of equipment to be connected, and determine the type of PSU that will be required.

*1 Only the extension cards that can support SLTs count for the load figures.

Each PSU supports a different amount of load figures.

The power unit supplies power to the various cards of the KX-TDA100 and KX-TDA200 and KX-TDA600.
The functions of the power unit are listed below.

Two kinds of power supply unit are provided as an option depending on the card structure and the terminal structure for KX-
TDA100 and KX-TDA200 and KX-TDA600.

Function

Description

DC voltage generation function

This function generates four DC voltages (+41V, +30V, +15VPT, and +15V) from the AC power supply and 
supplies them to the system.

AC cutoff detection function

This function detects any cutoff of AC power supply and outputs an AC alarm signal to the MPR card.

DC abnormality detection function

This function detects any abnormality in the DC voltage and outputs a DC alarm signal to the MPR card.

Overheating detection function

This function detects any overheating of the power unit and shuts down the power supply in order to pre-
serve the safety of the system.
