5 Installation
Always read the safety information before installation. The fan is intended for fixed installation. Installation requires an
inspection of the hazardous area to be done according to applicable regulations and classification standards (within the
EU, EN 60079-10).
Installation according EN 60079-14 deemed to meet the installation requirements in the EU. Compliance with the Direc-
tive 2014/30/EU "Electromagnetic Compatibility" applies only when the product is directly connected. Integrated into
an electrical system or combined with other components (e.g. controls/control equipment) the installer/plantholders
are responsible for compliance.
The installation must be set up at a safe distance to transmitter units or protected with suitable screens.
Before starting installation check for any transport damage and that the impeller do not touch parts of the fan housing
(distances must not be less than 3 mm at any point). Ambient temperature and the conveyed air temperature should
be between -20°C and +40°C. DKEX/KTEX are intended for continuous operation within the specified temperature
range.
The fan can be mounted in any direction. Install DKEX/KTEX in the correct air direction (arrow on housing). The fan must
be installed so that service and maintenance can be performed easily and safely. Make sure the fan is firmly fixed and
securely anchored. DKEX/KTEX must be installed so that vibrations can not be transmitted to the duct system or building
structure.
Disturbing air noise can be avoided by installing silencers (accessory).
Duct installations must be carried out so that ingress protection class IP 20 (mesh width less than 12mm) is fulfilled on
the inlet and outlet side. Parts that assure the IP classification must be correctly designed with regard to strength and
material.
Rust particles must not be present in the air stream.
Components that are installed before or after the fan or that are in the direct air stream may not have unprotected alu-
minium or steel surfaces. A surface protection that at least fulfills the crosscut test parameter of 2 / DIN EN ISO 2409 is
necessary to prevent an aluminothermic reaction.
Mains circuit breaker must precede the fans. Electrical connection carried out according to wiring diagram, chapter 4.3.
Wiring diagram must be available in the workplace. All fans for 3-phase (Δ/Y) are supplied from factory wired for 400V
3-phase (Y). If electrical connections are made inside explosive environment then the used components must be in-
tended for the relevant Ex environment. When the free end of the permanently connected cable terminates in hazard-
ous area, it shall be protected by type of protection listed in clause 1 of EN 60079-0:2012. The mains supply for
explosion proof fans must be fixed. Supplied with extended connection cable.
If there is a risk of lightning strikes the installation must be protected with suitable lightning protection.
The connection cable on KTEX is secured with cable ties in order to guide the cable correctly in relation to the hinge on
the hatch. Attachment must be carried out so that the cable can still be extended after fixing without the cable insula-
tion being damaged.
