Terminal plan electrical panel I/O module (M172)
7.3 Compressor modules (CM-SW), additional motor boxes, oil separator module (CM-IO)
The connections to the compressor modules, the additional motor boxes and the oil separator module are all
pre-wired and connected from the factory.
7.4 Economizer system module (CM-IO)
When using an economizer, it must be connected according to the terminal plan in section 7.1. The customer
must connect (cables supplied by customer) the economizer system module with the ACP LINK panel:
Supply 230/115 VAC, connect to CN1
Supply 24 VDC, connect to X54:DC- and X54:DC+
Modbus RTU, connect to CN14
