Installation

8.4.1 Preparation
 Before installation, examine the base for stability.
 Transport the packed fan to his place of installation.
 Remove the packaging.
 With the help of the fan, set the precise positions of the set screws.
 Drill the necessary fi tting holes.
 When selecting the fi tting material, pay attention to the weight, vibration tendency and shearing forces (weight,
see name plate).
8.4.2 Fitting
 Fit the fan securely on the base.
 Check the fi rm fi r of the screws.
 Use the vibration dampers (option).
8.4.3 Connect feed and water air channels
 Connect feed and water air channels. Pay attention to the direction of fl ow (arrows).
 If available, install the condensation opening on the bottom of the housing in order to drain the condensation off.
 Set up a device for conducting and trapping the condensation
8.4.4 Install protective devices
 Install fi xed protective grids and protective barriers in order to prevent access to the fan under normal operating
conditions.
8.4.5 Lightning protection device
 If the risk assessment shows that there is the risk of an atmospheric discharge, lightning protection measures must
be taken. For reasons of operational safety, provide for a suitable lightning protection system according to country-
specifi c directives (e.g. DIN VDE 0185).

Electrical connection

HAZARD
Hazard of explosion of an ignition-capable gas/air atmosphere!
If the wire ends which have not been connected are fi tted to the external current circuits within the
explosion-capable area,
»
a connection box selected to match this area with its own certifi cation and explosion-protection
identifi cation must be used
»
the electrical data, information on temperature monitoring and on admissible operation with part
voltage, if applicable, can be seen from the data sheet in question.
Protection against explosions in general:
»
Always ensure potential compensation.
