Hardwiring is the most common way to bring power and signal to a machine because of the perceived savings in installation costs. But, according to Lapp Group, this assumption is wrong, as there are many “hidden installation costs” that many companies fail to consider.
The hidden costs
Many machines have to be disassembled for shipping and reassembled for startup, which adds time and labour because parts are being hardwired twice. This also increases the chance for field wiring errors, which can cause delays in machine commissioning, as well as damage the machine. There is also the added cost of testing, which can be complex and expensive in hardwired systems.
These hidden costs will grow exponentially with the number of connection points on the machine. However, all of these added costs can be avoided through connectorization. In its recent white paper, “Connectors lower wiring costs”, Lapp Group explains these advantages.
There are many ways connectors help to reduce costs. These include:
- Lower cost machines: Connectors give engineers the flexibility to create modular machines that are faster and less expensive to build because common subsystems and components can be pre-built, tested and stocked for installation. Connectorization provides the plug-and-play assembly that makes modular machines so attractive from a cost standpoint because they are easier to assemble and ensure wiring integrity.
- Faster shipment: When new, large machines get ready to ship, cables to and from the control panel are disconnected for shipping. With hardwired machines, this step can be time consuming, expensive and fraught with error. With connectorized machines, you simply unplug cables from the panel’s bulkhead connectors, while wire routing and connections internal to the panel can remain undisturbed.
- Quicker commissioning: Once the machine arrives at its destination, all wires disconnected for shipment need to be reconnected. In many cases, local electricians perform this crucial rewiring process using a set of wiring schematics. Since the electricians may know little about the machine and how it works, the rewiring process is notorious for costly mistakes and startup delays. Machine builders sometimes minimize this risk by sending factory technicians to complete the installation, which adds costs. With connectorized machines, the need to rewire the machine in the field, and the possibility of wiring mistakes, are eliminated, reducing costly troubleshooting and replacement of damaged components.
