1.6 Mechanical Installation
Dimensions and mounting hints see (➜ # 133) and refer to the MKD Installation Manual.
1.6.1 Important Notes
MKD-C and MKD-N devices must be mounted in cabinets only with protection class IP 54
according to IEC 60529.
Risk of electrical shock, if the servo amplifier (or the motor) is not properly EMC-grounded.
Do not use painted (i.e. non-conductive) mounting plates.
In unfavourable circumstances, use copper mesh tape between the earthing bolts and
earth potential to deflect currents.
Protect the device from impermissible stresses. In particular, do not let any components
become bent or any insulation distances altered during transport and handling. Avoid con-
tact with electronic components and contacts.
The modules will switch itself off in case of overheating. Ensure that the mounting space
matches the requirements (➜ # 15).
Do not mount devices that produce magnetic fields directly beside the device. Strong mag-
netic fields can directly affect internal components. Install devices which produce magnetic
field with distance to the MKD-C and/or shield the magnetic fields.
1.6.2 Guide to Mechanical Installation
For details refer to the MKD Installation Manual.The following tools are required (at a min-
imum) to install the MKD-C and MKD-N modules; your specific installation may require addi-
tional tools.
M4 hexagon socket-cap screws (ISO 4762)
3 mm T-handle Allen key
No. 2 Phillips head screwdriver
Small slotted screwdriver
Install the modules as follows:
1. Prepare the site. The MKD modules must be mounted in a closed control cabinet (➜ #
15). The site must be free from conductive or corrosive materials.
2. Check that the ventilation of the modules is unimpeded, and keep within the permitted
ambient temperature (➜ # 15). Keep the required space clearance above and below the
modules (➜ # 133).
3. If cooling systems are used for the control cabinet, position the cooling system so that
condensation water cannot drip onto the modules or peripheral devices.
4. Assemble the power supply module and the drive modules on the conductive, grounded
mounting plate in the cabinet.
5. Ground the modules, the mounting plate, motor housing, GND of 24V supply and CNC-
GND of the control system.
For mechanical installation of AKD-N to the machine, refer to the AKD-N Installation
Manual.
