SAFETY CONSIDERATIONS
Warnings and Cautions
As with any electro-mechanical device, safety must be considered
during the installation and operation of your Tritex II Series actuator.
Throughout this manual, you will see paragraphs marked with CAUTION
and WARNING signs as shown below:
“WARNING”indicates the information following is
essential to avoiding a safety hazard.
“CAUTION” indicates the information following is
necessary for avoiding a risk of damage to the product or
other equipment.
General
Failure to follow safe installation guidelines can cause
death or serious injury. The voltages used in the product
can cause severe electric shock and/or burns and could be lethal.
Extreme care is necessary at all times when working with or adjacent to
the product. The installation must comply with all relevant safety
legislation in the country of use. The forces created by actuator could be
lethal or cause severe injury if proper protection is not provided to keep
personnel away from moving components.
System Design and safety for personnel
The actuator is intended as a component for professional
incorporation into complete equipment or a system. If
installed incorrectly, the actuator may present a safety hazard. The
actuator uses high voltages and currents, carries a high level of stored
electrical energy, and is used to control equipment which can cause
injury. Close attention is required to the electrical installation and the
system design to avoid hazards either in normal operation or in the event
of equipment malfunction. System design, installation, commissioning

and maintenance must be carried out by personnel who have the
necessary training and experience. They must read this safety
information and this manual carefully.
None of the functions or features of the Tritex actuator may be
used to ensure safety of personnel, i.e. they must not be used for
safety-related functions.
For example the actuators enable / disable, brake, stop/start and
forward/reverse functions are not sufficient for use in safety-critical
applications without additional independent channels of protection.
Careful consideration must be given to the functions of the actuator
which might result in a hazard, either through their intended behavior or
through incorrect operation due to a fault. In any application where a
malfunction of the actuator or its control system could lead to or allow
damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk.- for example a
failsafe brake in case of loss of actuator braking power.
Never attempt to connect or disconnect the actuator
with power applied.
Dangerous voltages are present. Damage to equipment
and injury to personnel can result. Refer to the following warnings on
supply isolation and stored energy discharge time for more information.
Supply isolation
The AC supply or high voltage DC supply must be
removed from the actuator using an approved isolation
device or disconnect before any maintenance is performed except
adjustments to the settings or parameters as specified in the manual.
Risk of Electric Shock.
Allow 3 minutes for Discharge Time.
The actuator contains capacitors that remain charged to a
potentially lethal voltage for up to 3 minutes after the
supply has been removed. Do not touch power wiring or terminals until
this discharge time has expired.

If connected by plug and socket
A special hazard may exist where the actuator is
incorporated into a system connected to the AC supply by
a plug and socket. The pins of the plug are not generally isolated from
the charge stored in the bus capacitor, so must be considered electrically
“hot” until the discharge time has expired. It is the responsibility of the
user to avoid any possibility of electric shock from the pins when they are
accessible.
Grounding - High Leakage Current
The drive must be grounded by a conductor sufficient to
carry all possible fault current in the event of a fault. This
equipment has high earth leakage current. You must comply with local
safety regulations with respect to minimum size and special installation
requirements on the protective earth conductor for high leakage current
equipment. The instructions for ground connections shown in this manual
must be followed.
Compatibility with Residual Current-operated
Protection Device (RCD)
This product can cause a DC current in the protective
earthing conductor. Where a residual current –operated protective (RCD)
or monitoring (RCM) device is used for protection in case of direct or
indirect contact, only an RCD or RCM of Type B is allowed on the supply
side of this product.
Hot Surface – Risk of Burn.
Exposed surfaces of the actuator may exceed 70 degrees
C under normal operation and can take a long time to cool,
resulting in a risk of burns when touched.

Additional Information Related to UL
Motor Over temperature Sensing is not provided by the Drive
Though Tritex II AC has a high temperature limit switch built into the
motor, its overall function has not been approved by UL for motor over
temperature protection and is therefore not used as the basis for motor
overload protection.
Electronic Overload Protection
Solid state overload protection is provided in each model at no more
than 110% of rated output torque / force. This overload protection is
based on maximum continuous current capacity. It will allow up to 200 %
of rated output to be delivered for the amount of time determined by the
following chart:
