Terminal Block Labels

Terminal blocks are insulated, modular blocks that secure two or more wires together. They are the perfect solution for complicated control circuits that require secure, well-organized and semi-permanent wire connections that can easily be switched out for repair or inspection in the field. Within a control board, terminal blocks are snapped firmly into place on a mounting or DIN rail. When modifications to the circuit are performed, they can easily be added or removed from the rail without interfering with other wire connections.
Terminal block marking ensures that the wiring in control cabinets is clearly assigned, which helps to prevent errors during setup, maintenance and repair work. Terminal markings differ primarily with regard to the mounting type. Markers are available for tall and flat marker grooves, as strips or as marker pins. There are marked and unmarked terminal markings available in card, roll, or sheet format. Phoenix Contact provides a comprehensive range of versions that allow secure positioning on terminal blocks. The THERMOMARK E.VARIO applicator marks entire terminal strips with just two materials in continuous format for high and flat marking grooves. Due to the continuous format, all widths between 3.5 mm and 1,000 mm can be realized, regardless of the number of different pitches.

Labeling an Industrial Control Panel Tips and Tricks
Wire Labeling:
- Establish a method and stick to it.
- Good practice to show where the wiring is coming from and where it is going
- Don't put too much information on the label as it can become confusing and difficult to read
- Size the labels properly and don't heat shrink until testing has been completed.
Hardware Labeling:
- Clearly label all hardware and make sure it makes sense to end user
- Good practice to make sure all IP addresses are on all radios, PLCs and network equipment
- Make sure to list any voltage or amperage considerations for hardware if necessary
UL Labeling:
- Must have a main panel ID
- This label should include input voltage, short circuit rating, FLA and fuse legend
- Wire labels should match the drawing provided
