2 SO 2-Ex
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 Information
1.1 Purpose and Application
Explosion-proof electric multi-turn actuators
(hereafter referred to as EA ), types SO 2-EX respectively SO
with controller are high performance electro-mechanical products, designed for direct assembly on
controlled devices . EA of SO 2-Ex types are provided for remote control of closing bodies, and EA of SO
2-Ex with controller for automotive control of regulating bodies. They are equipped by measuring and
technological processes controlling means; the information carrier on their
input
and/
or
output is unified
analogue direct current, or voltage signal. They can be used in heating, energy, gas, air-conditioning and
other technological equipments, for which are suitable due to their manufacturing qualities. They are
assembled by means of flange and connecting component in accordance with ISO 5210 , resp. DIN 3338,
resp. GOST R 55510.
1. It is forbidden to use the EA as a lifting mechanism!
2. Switching of actuator by a semiconductor components/switches have to be consulted with
producer.
1.2 Safety Instructions
Product characteristics from risk point of view
EA are reserved technical devices with higher rate of danger (group A), with possibility of
installation in areas specially danger regarding casualties caused by electric current. EA are according to
directive LVD 2014/35/EU and standard EN/IEC 61010-1 within valid edition assigned for installation
category II (overvoltage category).
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 EN standards as well EN/IEC 61000-6-4+A1,
EN/IEC 61000-6-2, EN/IEC 61000-3-2 and EN/IEC 61000-3-3 within valid edition.
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 80dB (A).
Electric actuators are made in explosion-proof version Ex db eb h II B T5 Gb and
Ex h tb IIIC T100
