1.5 Mechanical Installation

Dimensions overview see (➜ # 147).

1.5.1 Important Notes

Protect the PCMM 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 PCMM will switch itself off in case of overheating. Ensure that there is an adequate
flow of cool, filtered air into the bottom of the control cabinet, or use a heat exchanger.
Do not mount devices that produce magnetic fields directly beside the PCMM. Strong mag-
netic fields can directly affect internal components. Install devices which produce magnetic
field with distance to the PCMM and/or shield the magnetic fields.

1.5.2 Guide to Mechanical Installation

The following tools are required (at a minimum) to install the PCMM; your specific installation
may require additional tools:
M4 hexagon socket-cap screws (ISO 4762)
3 mm T-handle Allen key
No. 2 Phillips head screwdriver
Small slotted screwdriver
Install the PCMM unit as follows:
1. Prepare the site.
Mount the PCMM in a closed control cabinet. The site must be free from conductive or
corrosive materials.
2. Check ventilation.
Check that the ventilation of the PCMM is unimpeded, and keep within the permitted
ambient temperature (➜ # 12). Keep the required space clearance above and below the
PCMM.
3. Check cooling system.
If cooling systems are used for the control cabinet, position the cooling system so that
condensation water cannot drip onto the PCMM or peripheral devices.
4. Mount the PCMM.
Assemble the PCMM and power supply near each other on the conductive, grounded
mounting plate in the cabinet.
5. Ground the PCMM.
Ground the mounting plate, PCMM housing and CNC-GND of the control system.
