WARNING!
Explosion hazard
• The technical specifications in the document "T100 Control drawing for hazardous areas" must be observed.
• When used in potentially explosive atmospheres, the ECO must be operated via suitable isolating amplifiers
or ten barriers.
• To avoid a possible ignition hazard, the versions with aluminum housing must not be exposed to shocks or
friction from other components.
NOTE:
• The installation of the ECO in potentially explosive atmospheres must be carried out by appropriately
trained personnel.
• If the installation is not carried out in accordance with the manufacturer's specifications, the safety for the
corresponding type of protection is invalidated.
• When using long connecting cables, ensure that the maximum capacities and inductances for the
corresponding voltage and gas group are not exceeded.
• If the housing of the ECO is opened by unauthorized personnel, the safety for the corresponding ignition
protection type is void.
• Repairs may only be carried out by the manufacturer.
