Installing the BMXERT1604T/H Time Stamping Module

Overview

The BMXERT1604T/H time stamping module is powered by the backplane bus. The modules may be handled without turning off power supply to the rack, without causing any danger and without any risk of damage or disturbance to the PLC.

The fitting operations (installation, assembly, and disassembly) are described below.

Installation Precautions

The BMXERT1604T/H module may be installed in any of the positions in the rack except:

the positions reserved for the rack power supply modules (marked PS, PS1, and PS2),
the positions reserved for extended modules (marked XBE),
the positions reserved for the CPU in the main local rack (marked 00 or marked 00 and 01 depending on the CPU),
the positions reserved for the (e)X80 adapter module in the main remote drop (marked 00).

Before installing a module, take off the protective cap from the module connector located on the backplane.
