MTL fieldbus networks
9377
MTL fieldbus barrier module
Introduction
The 9377-FB-R Fieldbus Barrier module is the main active component
in the 9370-FB range Fieldbus Barrier System for F
fieldbus networks and provides six intrinsically safe fieldbus spurs
from a single incoming trunk.
See the 9370-FB technical datasheet for full product details.
The 9377-FB-R Fieldbus Barrier module may be fitted or removed
without the need to isolate trunk power. The trunk connections
to the barrier module on the carrier have spark suppression by
design and cannot cause ignition while they are being connected
or disconnected.
The 9377-FB-R module may be installed or removed
without isolating the trunk power.

Compatibility
The 9377-FB-R module may be used as a direct replacement for
type 9377-FB in all 937x-FB-xx-xx range (enclosure) and 938x-FB-xx
range (open frame) Fieldbus Barrier systems.
Installing a module
Remove the module from any packaging provided.
Do not use, or attempt to repair, a module that has any of the
pins on its underside bent or damaged, because this might affect
its safety and invalidate the certification.
• Engage the two locating guides (A) on the underside of the
9377-FB-R Fieldbus Barrier module into the sockets provided
on the carrier and push the module into place, locating the
barrier loop over the retaining clip (B).
• Three spring-loaded fixing screws (C) are provided. Start each
one in its threaded hole on the carrier and then tighten them on
each side and at the top of the module (recommended torque
of 0.9Nm) to secure the module.
Removing a module
Removal is a two-step process that first breaks the electrical
connection, followed by the physical removal of the module from
the carrier.
• Loosen the three captive fixing screws (C) on the module to
release it. The screws are spring-loaded and should retract
when the thread has fully disengaged.
• Slowly pull the 9377-FB-R Fieldbus Barrier module away from
its connections on the carrier until the safety retaining clip (B)
stops further removal.
Press the clip towards the module - see removal diagram - until the
barrier is released and can then be removed completely.
