Mounting The System - ABB AC500 Introduction Manual

Important: Horizontal mounting is highly recommended. Vertical mounting is possible,
however, derating consideration should be made to avoid problems with poor air circulation and the
potential for excessive temperatures (see also the AC500 system data, operating and ambient
conditions, for reduction of ambient temperature).
Note: By vertical mounting, always place an end-stop terminal block (e.g. type BADL, P/N:
1SNA399903R0200) at the bottom and on the top of the modules to properly secure the modules.
By high vibration applications and horizontal mounting, we also recommend to place end-stop
terminals at the right and left side of the device to properly secure the modules, e.g. type BADL,
P/N: 1SNA399903R0200.

ATTENTION
Mounting and Demounting of the Terminal Unit and Electronic Module
Mounting on DIN rail
Step 1: Install the 7.5 mm or 15 mm DIN Rail
Step 2: Snap the FBP-Terminal Unit (TU505 or TU506)
Figure: Mounting of the FBP Terminal Unit (TU505 or TU506)
The FBP Terminal Unit will be placed on top of the DIN Rail and then snapped on the bottom. Follow the
reverse order to disassembly.

Introduction to AC500
During panel or DIN rail mounting of all devices, be sure that all debris (metal
chips, wire strands, etc.) is kept from falling into the controller. Debris that falls
into the controller could cause damage while the controller is energized.
