OPTINAL DEVICES

10.1 - RECOMMENDED DRIVE WITH CONTROL BY DIGITAL INPUTS

WITH THREE WIRES AND BYPASS CON MAC-0X.

OPTIONAL

MAC-0X

OPTIONAL

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.
