| type | core role | Structural features | Operation and Safety |
|---|---|---|---|
| plug-in (front panel) | It combines quick replacement with intuitive wiring and is compatible with standard cabinet wiring and mass assembly. | The insert base is mounted on the front of the panel, with the terminals facing outwards; wiring is completed on the front of the panel, making installation intuitive and requiring no special drilling. | Replacement can be performed by simply disconnecting the power and unplugging. Wiring and maintenance require space in front of the panel, and live parts are easily accessible, so caution is advised. |
| plug-in (rear panel) | This achieves concealed wiring behind the panel and no wiring at the front for maintenance, improving cabinet neatness and operational safety. | The terminals are located at the rear of the panel; the base can be installed through the panel or led to the rear of the panel using extension terminals; holes must be drilled according to specifications. | Replacement requires no wire removal, and front-end operations are less likely to come into contact with live terminals, making it safer; however, space must be reserved behind the board for wiring and heat dissipation. |

The main benefits include quick replacement and maintenance without disconnecting wires, reduced wiring error rates due to pre-connected bases, and seamless integration into standardized cabinet designs like drawer or fixed cabinets.
Front-panel installation features exposed terminals facing outwards with intuitive front wiring and requires no special drilling. Rear-panel installation conceals wiring behind the panel, which improves safety and neatness but requires specific panel drilling.
Yes. Because the wiring and live terminals are located on the back of the panel, operators working in front of the panel are prevented from accidentally touching live components, significantly reducing the risk of electric shock.
Yes, both front and rear plug-in types are highly adaptable to standardized cabinet sets, including drawer cabinets and fixed cabinets, allowing for pre-installation of the base and plug-and-play main units.
The dimensions and installation specifications cover the M5-160/250, M5E(i)-160/250, M5-400/630, and M5E(i)-400/630 models.
No, drilling is not required for front panel plug-in installations as terminals face outwards. Rear-panel plug-in installation, however, requires holes to be drilled on the panel according to the specifications to route the terminals to the back.
