Installation
TPS401 DIN Carrier Units
DIN Carrier Units fi t onto 32mm (EN50035) G-type
and 35mm (EN50022) Top Hat DIN-rails. They should
be mounted in a way to allow easy access to terminal
receptacles and to keep LEDs visible. Horizontal
DIN-rails are preferred so that air can fl ow vertically
between the Conditioners to assist in module cooling.
An outdoor location requires an external enclosure.
Any enclosure meeting the requirements of the
location in relation to electrical and mechanical safety
can be used (a minimum of IP54 is recommended).
Contact MooreHawke for specifi c advice regarding
installation of TPS400 Series in any hazardous area.
TPS202/TPS205 Power Conditioner
Power Conditioners fi t onto sockets on the Carrier
face. They only mount in one orientation and should
be secured to the Carrier using the on-board screws.
A jumper is fi tted to each unused socket and it must
be removed prior to module installation. Should
a Power Conditioner be removed, the Fieldbus
Diagnostics Module will indicate an alarm unless a
jumper is fi tted in the empty socket.
For duplex (redundant) power for the segment
confi guration, two Power Conditioners are required per
segment.
FDM252 Fieldbus Diagnostics Module
A Fieldbus Diagnostics Module (optional component)
will fi t onto a socket on the Carrier face. It only mounts
in one orientation. Use the on-board screws to secure
the module to the Carrier.
Fieldbus Diagnostics Modules are required for alarm
indication and alarm contact output, but removal or
non-installation does not affect the power supply
operation for the segment.
FDM252 Alarms
There are multiple reasons that a Fieldbus Diagnostics
Module may alarm. See Testing and Troubleshooting
sections of this manual for details. At installation,
errors will be shown if there are unused power
sockets. These errors can be removed by installation
of jumpers (see Figure 6).
Jumpers
The TPS400 Carrier Module is shipped with jumpers
fi tted into the appropriate unused power sockets
(as marked). These jumpers must be fi tted in any
unused power socket once the Carrier is used in an
application, or the alarm will be set on the Fieldbus
Diagnostics Module. Extra jumpers are supplied with
each carrier board.

Resistors
Additionally, since the TPS202 continually monitors
for open or short connections, if a TPS202 module is
installed on the Carrier and is not being used in the
system, the resistors provided (3.3kohm, 1W) in the
TRUNKSAFE Kit, P/N: 208-265-00, must be placed on
the Field and Host sides (at the + and – terminals not
required on the Host side if DB25 cable is used and
Interface/ Redundant adapter is connected) of that
segment to prevent the Fieldbus Diagnostics Module
from alarming. Resistors must be removed when the
Trunk cables and Host wiring is added.
Resistors must also be placed on the fi eld and Host
side terminals for bench test purposes.
