 While it is possible to use a standalone or a summable power supply with a DIO
drop (as long as the DIO input is left unpowered), it is not possible to use a
redundant supply with the DIO drop.

The added power supply must not be included in the system I/O map.

The added power supply need not be of the same type as the DIO adapter. AC
powered supplies may be used with DC type adapters and vice-versa.

DIO module current load with an added power supply is typical

Grounding
Overview This appendix provides information on grounding issues for the chassis, power
supply Modbus Plus, and other equipment and system requirements.
Chassis
Grounding
A chassis ground wire is required for each backplane. The wire is connected
between one of four ground screws (located on the backplane) and the main ground
point of the power system. This wire should be green (or green with a yellow stripe)
and the AWG rating must be (at a minimum) sized to meet the fuse rating of the
supply circuit.
Power Supply
Grounding
On each power supply connector there is a ground connection. This connection
must be made for safety reasons. The preferred connection is between the power
supply connector ground terminal and one of the backplane ground screws. This
wire should be green (or green with a yellow stripe) and at a minimum the same
AWG rating as the power connections to the supply.
In backplanes with multiple power supplies, each supply should have a ground
connection between its input connector and the backplane ground screws.
Modbus Plus
(MB+)
Communication
Tap Grounding
Modbus Plus network drop cables require a ground connection to the backplane.
The connection is made by means of a metal loop clamp that grounds the cable
shield to the ground point. The maximum allowable distance from the ground point
to the drop cable’s connector is 30 cm (11.8 in).
$    
%It is recommended that the power supplying the I/O modules be grounded at
the main ground point.

Grounding
Figure
The following figure shows Modbus Plus grounding information.
Other Equipment
Grounding
Other equipment in the installation should not share the grounding conductor of the
system. Each piece of equipment should have its own grounding conductor
returning to the main grounding point from which the equipment power originates.
Systems with
Multiple Power
Feeds
In systems with multiple power feeds, the grounding should proceed in the same
manner as single feed systems. However, a zero volt potential difference must be
maintained between the equipment grounding conductors of the separate systems
to prevent current flow on communication cables.

Closed System Installation
Overview For installations that must meet "Closed System" requirements, as defined in EN
61131-2 (without relying upon an external enclosure) in which an external Line Filter
is used, it must be protected by a separate enclosure which meets the "finger safe"
requirements of IEC 529, Class IP20.

    Only one ground wire per backplane is required.
