Field of a lication
The person authorized to do the work is responsible for the zones sharing. He must follow the norms EN 6007 -31
and EN6007 -14 (whenever their application is possible) when choosing the suitable motor.
Motive Delphi Ex motors are designed to be used in the zone 22 (II 3 D T125°C) and/or zone 2 (II 3 G T135°C),
according to the classification stated in the plate, and for the voltage and frequency field A described by the norm EN
60034 part 1 Cap. 6.3.
The eventual dust deposits mustn’t have a thickness > 5mm.
Conformity declaration
The conformity declaration reported in this addendum, is the document that testifies the product conformity to the
Directive 2014/34/UE.
The validity of such certificate is related to the respect of the instructions specified in the use and maintenance
manual, together with the following additional instructions.
Additional instructions
The persons authorized to do the work in an ambient exposed to explosion risk must be instructed about the right
procedure for the use of the motor, respecting all norms related to safety, installation and use.
Motors must be protected against over-heating by suitable control means that must be chosen, considering the
working conditions, according to the norm EN6007 -15, EN6007 -0 and EN6007 -31.
In order to help such control, all Motive motors from size 160 up to size 400 are provided with
3 PTC thermistors 130°C. 3PTC thermistors 130°C are also provided in any Delphi-Ex motors,
of any size, when identified for zone 2.
It is forbidden to o en the terminal box to connect electric wires or make any
intervention in resence of ex losive atmos here. Before any of such o erations,
disconnect the motor from the electric ower su ly and avoid the ossibility of any
accidental switching on of the motor.
