Precautions For Installing The Base - Honeywell ML200 Series Installation And Commissioning Manual

Precautions for installing the base

The following precautions must be taken while installing a PLC on the Control Panel. Ensure sufficient
ventilation for the modules, especially the upper part of the modules. In addition, this helps in changing
the modules, if required.
1. A, B: More than 5cm.
2. C, D: More than 5cm for easy installation of module.
More than 15cm is recommended if fiber optic modules or full loaded power supply is used.
l
3. E: More than 8cm, if fiber optic cable or connector-type I/O modules are used or more than
10cm, if the FTP cable is used.
4. If the PLC is installed near a Contactor/Breaker, it is recommended to use a Contactor/Breaker
(Large Size) in a different panel.
5. If necessary, install wiring duct for routing the cables. Consider the following points while
installing a wiring duct:
When installing the wiring duct on the upper part of the PLC, ensure that its distance is more
l
than 50mm to enable adequate ventilation. Maintain sufficient distance from the upper part
of the PLC so that the module can be removed easily.
When installing the wiring duct on the lower part of the PLC, take into account the
l
connection of the optical cable or coaxial cable, and the minimum cable radius.
6. Install PLC in the direction as shown in the following figure. This helps in protecting the PLC
from radiation.
7. Do not install the PLC in the direction displayed in the following figure.
