Solenoid drive
Series MG.., MG..A, MG..A..C (no explosion protection)
Series MG..Xn, MG..A..Xn, MG..A..C..Xn (with - protection
for the intended use in zone 2) in accordance with
2014/34/EU (ATEX 95))
Special condition for safe use
1. Since temperatures higher than 70°C occur at the cable entry and higher than 80°C at the core
junction, this equipment must be additionally marked with the higher temperature (label at the cable
entry). Only a heat-resistant cable may be connected.
2. The solenoid actuators need to be protected against the dangerous consequences of short circuits,
earth faults and overloads. A line-side fuse appropriate to the rated current (max. 3xIB acc. to IEC
60127-2-1) is to chosen. A line-side motor circuit breaker - with short-circuit and thermal instantaneous
tripping - is to be adjusted for the rated current. If the magnet has very low rated currents, fusing with
the lowest current value in keeping with the stated IEC standard is sufficient.
Protective devices must be of the kind that prevents automatic reconnection under fault conditions. The
fusing rated voltage must match or exceed the specified nominal voltage of the solenoid actuator. The
breaking capacity of the fuse link must match or exceed the maximum short-circuit current expected at
the place of installation (usually 1500 A).
3. When a silicon (or silicon containing) connection lead is used or if the connecting lead is not
scratch proof respectively, this has to be protected from mechanical damage (e.g. inetrrupted
tube system with edge protection).
4. A maximum permissible ripple of 20% is valid for all magnets of dc-design.
Electrical connection
The diameter range / clamping range of the cable gland must be noted and adhered to. The connection
thread of the cable gland amounts up to 30 Watt M16x1,5 , from 40 Watt M20 x 1,5.Where a flexible
connecting line is used, insulated wire-end sleeves with plastic collars conforming to DIN 46228 part 4 are
to be used. The voltage supply at the solenoid actuator must lie within the range -15% to +10%. The
appropriate circuit diagram can be obtained from the connection diagrams at the end of these operating
instructions. To guarantee an IP65 degree of protection, the magnetic housing lid must be refitted carefully.
Versions supplied with a connecting cable ex works are ready for use, i.e. the connection compartment
does not need to be opened again.
The capacitors in the solenoid valve control TS800C must be discharged by an expert.
CE-Identification
The Council of the European Community passed common directives for the free movement of goods within
the European Community, which determine the minimum requirements for safety and health protection.
The CE-identification confirms, that the products correspond to the EC directives, i.e. are in agreement with
the relevant, especially harmonized standards.
Note concerning directive 2014/34/EU (explosion protection directive ATEX 95):
The solenoid drives (MG..Xn, MG..A..Xn, MG..A..C..Xn) fulfil the relevant requirements of directive
2014/34/EU; therefore they have the CE-identification as per annex X of the directive. The declaration of
conformity is included.
Note concerning directive 2014/30/EU (EMV-Directive):
The solenoid drives fulfil the requirements of the specification to be applied of the product families con-
cerning the industrial sector as well as the sectors of private housing, business and trading, as well as of
small businesses.
On using of AC- and DC-variants the user must provide a suitable mains filter (e.g. X-capacitor 47 nF) at
the mains entrance to attenuate the physically caused line-related turn-off current of the solenoid.
In the sense of the EMV-directives solenoid drives with driving elements for valves are not regarded as
independently operable appliances and are only processed further by expert companies, or respectively
installed into a machine. They must not be started up until it was determined that the machine, or respec-
tively, the complete line, corresponds to the regulations of the EMV-directives.
