  • Page 1 Electric rotary multi-tur n actuators Explosion-proof design Typ e n umber s 52 120 - 51 125 11/11...
  • Page 3 The Mounting and Operating Instructions specify basic principles for mounting, connection, adjustment, opera- tion, maintenance, and repairs of electric explosion-proof actuators. A fundamental prerequisite is that assembly, operation, maintenance, and revisions are performed by skilled technicians qualified for operation and works on explosion-proof electric devices and the works are supervised by a professionally qualified expert instructed in a demonstrable way.
  • Page 4 Designation of explosion-proof properties It consists of the following symbols: Electric device complies with the standard ČSN EN 60 079-0 and related standards for various types of protection against explosion. Designation of the type of protection against explosion, explosion-proof closure according to ČSN EN 60 079-1.
  • Page 5 b) explosion-proof closure “d” of terminal box with block of local control and display 6) Plate with marked manufacturer and manufacturer's address. 2) OPERATING CONDITIONS, OPERATING POSITION Operating conditions the MODACT MOED EEx actuators should withstand the effect of operating conditions and external influences, Classes AA7, AB7, AC1, AD5, AE5, AF2, AG2, AH2, AK2, AL2, AM2, AN2, AP3, BA4, BC3 and BE3N2, according to ČSN Standard 33 2000-3.
  • Page 6 Operating position ® Working position of actuators MODACT MOED EEx actuators with plastic lubricant – any position. The actuators with plastic lubricant are labelled “Filled: solid grease” on the power box at the side of the hand-wheel. Actuators with oil charge – position limited only by slope of electric motor axis – max. 15° under the horizontal level.
  • Page 7 4) TECHNICAL DATA Supply voltage The actuators have been designed to operate at supply voltage of 3 AC 400 V / 50 Hz. However, they are available in design variants operating at another three-phase AC supply voltage, upon special request. The supply voltage of the electric motor should be within the tolerance limits of ±10 % of the rated value and the supply voltage frequency should be within ±2 % of the rated value.
  • Page 8 5) ACTUATOR OUTFIT Anti-condensation heater The actuators are fitted with an anti-condensation heater preventing condensation of water vapour. It is connected to the AC mains of voltage 230 V. Local control Local control serves for controlling the actuator from the site of its installation. It includes two change-over switches: one with positions “Remote control - Off - Local control”, the other “Open - Stop - Close”.
