Installation location
and restrictions Installation location: It can be installed in 4 directions. Please refer to "2.2
Installation Location Requirements” for details.
2.2 Installation Location Requirements
This product can be installed in four positions (i.e. installation direction): horizontal, vertical,
and top and bottom of electric cabinet and horizontal direction is recommended. Different
installation positions have different working temperature requirements and limits. For details, please
refer to "2.1 Installation Environment Requirements".
◼ Optimal installation position
The best installation position of this product is horizontal, and heat dissipation is designed by
natural convection. To ensure normal ventilation and heat dissipation, sufficient wiring space, the
