The control board card assemblies are ESD sensitive electronic components. It
is necessary to take precautions in order to avoid the damage of these
components during the handling of the card in case an operator touches the
control board (in particular during service operation).
Proper ESD protection must always be applied when handling this card. ABB can
supply a document regarding to ESD protection.
The following basic rules need to be observed:
1. Handling of MABS1 CONTROL BOARD cards during assembly or replacement operation
must be limited to the minimum time.
2. Always hold a card by its edges.
3. Avoid touching the components assembled on the module.
4. Take care when connecting or disconnecting cables.
5. Avoid bending the card during wiring connectors insertion.
6. First, fix the control board to the panel. Then insert the filter card (if required) and wire
harness connections.
7. Prevent damage to the connectors by aligning connector pins before you connect the cable.
8. Remove and replace the board.
