often used for temporary connection to the Expert
™
software
configuration tool, but also used for connection to a Modbus
RTU host.
The enclosure cover may be removed for access to I/O and
power terminals and some wiring option jumpers. Removing
the cover also provides access to a battery for multi-turn
absolute feedback. Always replace the cover immediately to
prevent accidental entry of water, wire trimmings, or metal
cuttings from nearby drilling or cutting operations during
installation. See wiring section below.
4.2 SUPPLIED CONNECTORS
All standard models have connectors for external electrical
interface, though the connectors may be removed as needed
for direct wiring to internal terminals or connections.
The connectors are installed in M20x1.5 threaded holes
machined into the rear electronics housing and can be used as
cable entry ports. The power connector is installed in the right
rear port and contains main (motor) power connections. The
I/O connector is installed in the left rear port. The user may
remove or relocate the connectors as needed as long as any
unused holes are properly capped to prevent water or dust
intrusion. Adapters for 1/2 in NPT thread or cable glands may
be used but are not furnished.
4.3 GROUNDING (PE) CONNECTION
There is a protective earth (PE) terminal on the Tritex TTX080
internal power terminal block. On the Tritex TTX060, the PE is
located on the M20 power connector. These connections must
be used to ground the actuator case.
4.3.1 Shielding
In order to meet the European EMC Directive for an installation
to provide immunity from radio frequency (RF) interference and
to minimize RF emissions, the power and I/O wiring or cables
must be shielded. Metallic conduit (solid or flexible) can serve
as a shield. Shields must be connected to the enclosure at the
entry / exit point.

A PG 9 threaded hole is machined at the front of the electronic
enclosure. This hole has a connector installed for Ethernet
based communications options: PROFINET, EtherNet/IP, or
Modbus TCP. Otherwise, the hole is plugged but available for
alternate use.
All models have a RS485 connector for Modbus RTU
communications at the front of the electronics enclosure most
