Unpacking 

The REF542 bay control and protection unit does not require special shipping protection.

 The packaging is adapted for the shipping type and destination. Please proceed 

as follows: 

Visually inspect the unit and the packaging when unpacking it. 

Any shipping damage found in the packaging or the unit should be reported immediately

 to the last shipper, who should be informed in writing of liability for the damage. 

Check the delivery for completeness using the order documentation. 

If there is anything missing or any discrepancies with the order documentation, contact

 the ABB sales office immediately. 

Mount the unit as described in the following section. If the unit is not for immediate 

use, store it in a suitable place in its original packaging. 

 Mounting 

The REF542 plus consists of two parts, a Central Unit and a separate Human Machine

 Interface (HMI) as the Control Unit. The Central Unit contains the power supply, 

processor and analog and binary Input and Output (I/O) modules, as well as optional 

modules for supplementary functions. The HMI Control Unit is a stand-alone unit with 

its own power supply. It can be installed on the Low Voltage (LV) compartment door 

or in a dedicated compartment close to the Central Unit. The HMI is normally used to 

set the protection parameters and to locally operate the switching devices in the 

switchbay. An isolated and shielded twisted pair according to the RS485 standard interface

 shall be used for the connection of the HMI as the Control unit to the Central 

Unit.
