The unit must only be installed by suitably qualified personnel in
accordance with the latest issues of the relevant standards:
EN60079-14 / IEC60079-14: Explosive atmospheres - Electrical
installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive atmospheres -
Classification of areas. Explosive gas atmospheres
EN60079-10-2 / IEC60079-10-2: Explosive atmospheres -
Classification of areas. Explosive dust atmospheres
The installation of the unit must also be in accordance with any local
codes that may apply and should only be carried out by a competent
electrical engineer who has the necessary training.
