1.2 Product Identification
Each UniOP panel has a model identification plate on the back, which includes the following information:
Product model (e.g. eTOP33C-0050)
Production year and month (e.g. 06/08)
Serial number (e.g. 13435 35508)
Hardware version (H/W V)
Software version (S/W V)
Users should verify the model before installation to ensure consistency with engineering requirements.

Mechanical installation
3.1 Installation Preparation
Before installation, be sure to remove the red "BATTERY Protection" protective strip on the back of the panel.
The panel design is used for installation on the front panel of the control cabinet, and the installation opening size must strictly follow the drawings provided in this guide (tolerance ± 0.5mm).
The installation environment should avoid direct sunlight, corrosive chemicals, and ensure good ventilation.
3.2 Physical dimensions
The external dimensions and opening sizes of different models vary greatly. The following are some typical models' dimensions (unit: mm):
BKDC-46: 275 × 220 × 80, opening 262 × 206
