2.2 Installation Position
The PLC can be mounted horizontally, vertically, on top or at the bottom of the
electric control cabinet. Different installation positions require different operating
temperatures, see "
2.1 Installation Environment
"
on page 20
.
■ Optimal installation position
It is recommended to install the PLC horizontally, with natural convection as the
cooling mode. To ensure normal ventilation and heat dissipation and allow sufficient
wiring space, reserve enough clearance around the PLC, as shown in the following
figure.
Note
Keep the PLC away from high‑temperature heating sources (heater, transformer, large
resistor, etc.) by at least 100 mm.
