Avoid Loose Conductive Material
Always apply tape or heat shrink to the end of the shield to
prevent strands of the braided shield from breaking off and
shorting internal electronics or compromising spacing.
AC Input Power
Tritex II actuators require 100 VAC to 240 VAC (nominal) single phase
50/60 Hz to operate. The following sections contain important information
on ratings, acceptable power sources and connections, situations
requiring isolation transformers, overcurrent protection (fusing), and
details of wiring to power terminal blocks or connectors.
See diagrams below for connections to 3 phase and single phase
power sources.
The AC supply must be earthed with PE connected to the earthed
point at the source. In terminology used in the EU, Tritex II must be
connected to a Type TN system, and must not be used on a Type TT or
IT system without an isolation transformer so that the secondary can be
earthed.
Input Power Ratings
The following table shows rated input voltage and current. The
maximum voltage applied to the Tritex terminals must not exceed 264
VAC phase to phase or phase to PE ground. Operation on less than
rated voltage results in proportionally reduced maximum speed. Refer to
Torque/Speed diagrams in catalog for additional information.

AC Supplies NOT Requiring Transformers
If the distribution transformer is configured as shown in the figures
below, the AC power supply can be connected directly to the actuator
terminals without an isolation transformer.
