Disassembling and assembling the electronics module

NOTICE!
Incorrect handling can damage the electronics module.
• Never pull/push the electronics module from/into the interlinking block or pneumatic interface
when the power is switched on.
Electronics modules include electrostatically sensitive devices.
• Observe the handling specifications for electrostatically sensitive devices.
• Discharge static electricity from your body before assembling or disassembling modules to pro-
tect the modules.
– Switch off the supply voltages before assembly or installation.
– Only switch on the electrical supply voltages when all assembly and installation work is complete.
To avoid errors in assembly, both the interlinking block CPX-M-GE-EV-FVO and the electronics module
CPX-FVDA-P2 are mechanically coded. The coding prevents a different module from being plugged into
the interlinking block or the module from being plugged into an incorrect interlinking block.
The plugs connected to the manifold block on the CPX-M-AB-4-M12X2-5POL or cables on the
CPX-AB-8-KL-4POL can remain attached while disassembling the manifold block.
Before a CPX terminal can be extended or converted, it must first be unscrewed and disassembled.
Information can be found in the CPX system description.
CPX terminals are supplied from the factory completely assembled.
It may be necessary to disassemble and assemble the manifold blocks for the following reasons:
– Replacing the connection equipment
It may be necessary to disassemble and assemble the electronics module for the following reasons:
– Changing the DIL switch setting (PROFIsafe address)
– Replacing a defective electronics module
3.5.1

Disassembling the electronics module

To disassemble the electronics module (è 2.1.1 Design of the output module CPX-FVDA-P2):
1. Switch off the operating and load voltage supplies.
2. Unscrew the screws aJ and carefully lift off the manifold block 1 or 2 (è Fig.3) or the cover of
the pneumatic interface 1 (è Fig.4).
3. If necessary: pull the electronics module 3 carefully off the contact rails/the contacts in the
pneumatic interface or out of the manifold block.
3.5.2

Assembling the electronics module

NOTICE!
Incorrect handling can damage the electronics module.
• Never push the electronics module into the interlinking block or the pneumatic interface when
powered.
