Environmental Conditions; Installation Conditions; Heat Protection Design Of Control Panel - Honeywell ML200 Series Installation And Commissioning Manual

Chapter 3 - Plan and Install MLPLC
Basic/expansion base, power module, CPU module, expansion driver (only for ML200R), I/O
l
modules.
Synchronization cable (only for ML200R) and expansion cable.
l
USB programming cable.
l
SoftMaster (PLC Configuration and Programming Software)
l

Environmental conditions

Dos
Install PLC in a control panel, which is waterproof and can withstand vibration.
l
Ensure an ambient temperature of 0 ~ 55
l
Ensure incremental humidity: 5 ~ 95 %.
l
Don'ts
Do not expose PLC to direct sun-light.
l
Do not expose PLC to sudden changes in the temperature.
l
Do not expose PLC to corrosive or inflammable gases.
l

Installation conditions

While drilling holes, fixing screws or wiring, ensure that no wire or any other metallic part enters
l
PLC.
Do not install PLC on a panel that has a high-voltage device.
l
Maintain a distance of at least 50mm from the wiring duct or surrounding modules.
l
Ensure the grounding at a place where surrounding noise is minimal.
l

Heat protection design of control panel

In case the PLC is installed in an airtight control panel, the heat protection design must be
l
ensured, considering the radiation of other equipment, and heat from PLC. When air circulation
is provided using a vent or a general fan, the flow of dust particles or gas can hamper the
functioning of the PLC system.
Installing a filter or use of an airtight heat exchanger is recommended.
