Regarding the use of the Current Acquisition Module
(MAC-0x).
This optional device must be used to maintain the motor pro-
tections when the SSW-03 Plus is used with bypass contac-
tor.
To maintain the protections proceed as follows:
1. Remove the cables of the secondary winding of the
SSW-03 Plus current transformer from the connectors X3:3,
X3:4 and X3:5 of the CCS3.0x board. These cables must
be short-circuited in order to avoid damage of the cur-
rent transformers incorporated in the SSW-03. Use the
connector, wich is delivered with the MAC-0x. One end of
this connector has already a jumper that connects the
two contacts and the other end must be connected to the
cables removed from X3:3, X3:4 and X3:5.
2. Loose the thermostat cables that are connected to the X3:1
and X3:2 connector and connect the two free ends of the
plug-in connector that is delivered with the MAC-0x.
3. Connect this connector supplied with the MAC-0x to the
control board (CCS3.0x) in the place intended for the X3
connector.
4. Make the power connector as shown up.
