Important advices
Pay attention to the ESD advices.
Blank mounting surface, no lacquer (EMC surface-to-surface contact)
The unit must be safely protected in the switch cabinet against mist and water and the intrusion
of metallic dust.
Check the device for mechanical damage.
Only devices in perfect working order can be mounted.
Disconnect the power supply prior to any assembly.
For installations connected to an electric power supply install the
shorting plug and affix the warning signs.
The device must only mounted by suitably trained personnel.
Vertical mounting position.
Please note that there will be a performance reduction when the devices are mounted
horizontally.
Ensure that there is enough space for the discharged ventilation air (min. 100mm
).
Any bore hole dimensions for the fixation of the device must be taken from the dimension
diagrams or from the drilling plan, not from the device.
Drill the mounting bore holes into the mounting plate.
Insert the device and fasten the screws.
Note: Protect the device against intrusion of foreign particles (bore chips, screws, etc.)!
The filter and the choke have to be mounted near to the device
The line shields and the mounting plate must have surface-to-surface contact.
Unshielded cable heads must be kept as short as possible.
Braking resistors may become very hot (200°C).
Install the resistors such that neither persons will be injured (burns) nor
damage will occur due to the heat.
Use vibration-proof screw connections.
Inside temperature of the switch cabinet:
max. 45°C
For internal mounting ensure that the switch cabinet ventilation is sufficient.
Use an air conditioning unit if the room temperatures are too high (>30°C).
Note: The operation of bedewed devices is not permissible.
