Install the Mounting Base
To install the mounting base on the DIN rail, proceed as follows.
1. Position the mounting base vertically above the installed units
(adapter, power supply or existing module.
2. Slide the mounting base down allowing the interlocking side pieces to
engage the adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail. The mounting
base will snap into place.
4. To remove the mounting base from the DIN rail, remove the module,
and use a small bladed screwdriver to rotate the base locking screw to
a vertical position. This releases the locking mechanism. Then lift
straight up to remove.
Install the I/O Address Reserve Module
Use the 1734-ARM address reserve module to retain a node address for later
insertion of any future option. It can be installed in any slot with any key
position. However, we recommend that the key position be that of the
module that is intended to be installed in that position at a later date
.
The module can be installed before, or after base installation. Make sure that
the mounting base is correctly keyed before installing the module into the
mounting base. In addition, make sure the mounting base locking screw is
positioned horizontal referenced to the base.
ATTENTION
This product is grounded through the DIN rail to chassis
ground. Use zinc plated, yellow chromated steel DIN rail
to assure proper grounding. Using other DIN rail
materials (e.g. aluminum, plastic, etc.) which can corrode,
oxidize or are poor conductors can result in improper or
intermittent platform grounding.
