2 ST 0, STR 0
The Installation, Service and Maintenance Instructions are drawn up according to requirements of EC Executive
Nr. 2006/42/EC "Uniform requirements for machines and devices from the point of view of safety and health
care", to save life and health of users and to avoid material damages and exposure environment to danger.
1. General data
1.1 Purpose and applications
Electric linear actuators (hereinafter EA ) of ST 0 (hereinafter ST ) or STR 0 (hereinafter STR )
types are high-powered electric-mechanical products designed for direct installations onto controlled
devices (regulating bodies -valves, etc.). EA of ST types are provided for remote control of closing
bodies, and EA of STR types for automotive control of regulating bodies in both directions of their
movement. They can be equipped with means of measuring and control of technological processes
where an unified analogue direct current or voltage signal is an information bearer on their input and/or
output. They can be used in heating, energy, gas, air-conditioning and other technological systems,
which they are suitable for, regarding their features. They are connected with controlled devices with a
flange according to DIN 3358, or using a pillar or flange.
Note:
Do not count with tight closing performed by control signals of EA STR.
Switching of actuator by a semiconductor switches have to be consulted with producer.
It is forbidden to use EA as a lifting mechanism!
1.2 Safety instructions
1.2.1 Characteristics of the Product Regarding Its Exposure Rate
EA of ST and STR types are reserved technical devices with higher rate of danger, with
possibility of installation in areas specially danger regarding casualties caused by
electric current.
Electric actuators are according to directive LVD 2014/35/EU and standard IEC 61010-1:2010
assigned for installation category II (overvoltage category).
1.2.2 Product influence to environment
Electromagnetic compatibility (EMC): the product complies with the requirements of the Directive
2014/30/EU of the European Parliament and of the Council on the approximation of the laws the
Member States relating to the electromagnetic compatibility and with the requirements of standards as
well EN 61000-6-4:2007+A1:2011, EN 61000-6-2:2005, EN 61000-3-2:2014 and EN 61000-3-3:2013.
Vibrations caused by the product: product influence is negligible
Noise produced by the product : the maximum allowable noice level (A) of the product measured in a
place of operation is 78 dB (A).
1.2.3 Requirements for professional qualification of people performing installation,
service and maintenance
Electric connection can be performed only by an acquainted person, i.e. an electrical engineer with
professional education of electrical engineering at an apprentice school or a technical school
(secondary, complete secondary or university education) and whose qualification was verified by an
educational facility authorised to verify professional qualification.
