(1) IEC socket

This socket is used to establish the mains connection by means of a suitable cable.

The mains cable is not included as the mains connector type is different for each

country. A-100SSB/A-100LC1 has a wide range mains input, i.e. the mains voltage

can be in the range 100- 240V AC, the frequency can be 50 – 60 Hz.

Once again: In case of an A-100SSB please check before mains is

connected if the protecting metal cover is present and firmly mounted !

The unit does not have a mains switch. As soon as the mains connection is made A-

100SSB/A-100LC1 is working.

(2) Fuse holder and fuse

If it is necessary to replace the fuse please use only 800 mAT (time lag). Never use a

higher value or short the fuse. It may be necessary to replace the fuse when the unit

has been overloaded (e.g. by a defective module or a module that has not been

connected in the right way to the bus). Before you install a new fuse please remove

all modules from the bus to avoid that the fuse blows again.

Disconnect A-100SSB/A-100LC1 from mains before the fuse is replaced.

Use only the specified fuse value. Never use a higher value !

(3) Control LEDs

As soon as the mains connection is made all three control LEDs have to light up !

Otherwise something is wrong. If no LED turns on please check the fuse and remove

all modules. If only one or two LEDs turn on probably one of the modules causes a

short circuit or is not connected in the right way to the bus.

If no LED turns on after the fuse replacement and without any module installed

please return the unit to the dealer where you purchased it for checking!

(4) Pin headers for A-100 module connection (JP1 ...JP8)

These are the pin headers which are used to connect the A-100 modules. Up to eight

modules can be connected:

•

Please calculate the total current requirement of the modules that have to be

driven by the A-100SSB/A-100LC1

•

Check that this total is less than 380 mA for both +12V and -12V rails.

Otherwise the A-100SSB/A-100LC1 is not suitable.

•

If +5V is used the current is taken from the +12V source. In this case the

currents for +12V and +5V have to be added and the sum has to be not more

than 380mA.

•

Check if each module is equipped with a ribbon cable with a 16 pin female

connector at the open end. The ribbon cable can be 10 or 16 pin but the

female connector has to be 16 pin !

•

Now join the free end of the ribbon cable to the nearest available position on

the bus board

•

For this one has to plug the female 16 pin connector at the free end of the

ribbon cable to one of the pin headers of the bus (these are also 16 pins). Use

a pin header of the bus board that is close to the position where the module

has to be mounted later.
