| 1 | The foundations of a quick, easy, and trouble-free startup are laid before the control hardware even arrives onsite. Meeting with the electrical contractor prior to construction is important to establish a good working relationship, explain the requirements for a Crestron lighting control installation, and to exchange contact information so that any technical questions or concerns can be addressed prior to startup. | ||

| 3 | Though a pre-construction site-visit may seem like a wasted expense, by communicating expectations and requirements to the electrical contractor prior to startup you are actually able to save time and headache on-site. For large jobs especially, taking the time to ensure a proper installation will save hours or days during startup. Any time spent by a technician on-site tracking down serial numbers or troubleshooting/correcting a poor installation is a waste that could have been avoided with good communication and instruction prior to and throughout the installation process. | ||

| 5 | Covering these important topics with the electrical contractor during the pre-construction phase is critical to smooth ShowRunnerCLC™ startups. | ||

| 8 | |||
| 9 | * [[Wiring and Installation>>doc:SHOWRUNNER™ Setup Guide.Wiring Guide.WebHome]] | ||
| 10 | ** Do not power up panels until installation is complete and wiring is verified safe to connect | ||
| 11 | ** [[Cresnet wiring>>doc:SHOWRUNNER™ Setup Guide.Wiring Guide.Wiring Overview.Cresnet.WebHome]] (for jobs with Cresnet) | ||
| 12 | *** **Do** check for shorts before landing at the panel | ||
| 13 | *** **Do** land the shield with COM at the panel | ||
| 14 | *** **Do** splice through and insulate shield in the field | ||
| 15 | *** **Do** use wire nuts for Cresnet splices | ||
| 16 | *** **Do not** use lever-nuts for Cresnet splices | ||
| 17 | *** **Do not** leave copper showing at terminations | ||
| 18 | *** **Do not** excessively strip back the teal-yellow jacket | ||
| 19 | ** [[Ethernet terminations>>doc:SHOWRUNNER™ Setup Guide.Wiring Guide.Wiring Overview.Ethernet.WebHome]] (where the EC is terminating the Ethernet) | ||
| 20 | *** **Do** use T568B Pin-Out | ||
| 21 | *** **Do not** exceed 100m/328' cable length | ||
| 22 | ** [[Zūm Wired wiring>>doc:SHOWRUNNER™ Setup Guide.Wiring Guide.Wiring Overview.Zūm Net.WebHome]] (for Zūm Wired jobs) | ||
| 23 | *** **Do** follow the same rules as Ethernet for both Zūm Net and Zūm Link terminations/cable length | ||
| 24 | *** **Do not** mix up Zūm Net and Zūm Link cables | ||
| 25 | ** Follow the load schedule | ||
| 26 | * Serial number collection | ||
| 27 | ** SNs should be collected for all networked devices (all Cresnet devices and Zūm Wired devices) | ||
| 28 | *** If possible, SNs should be provided prior to startup. This way they can be put into the configuration prior to arriving on-site | ||
| 29 | ** The EC does not need to collect SNs for non-system devices (e.g. Crestron NS occupancy sensors, Steinel occupancy sensors, LDL photocells, and GLPPA-KP keypads | ||
| 30 | ** It is important to not just have a list of SNs on-site, but to be able to associate individual SNs with specific installed devices | ||
| 31 | ** The easiest way to do this is to write the SNs of installed devices on the floor plans or riser diagram as they are installed | ||
| 32 | * MAC address collection (optional) | ||
| 33 | ** Collecting MAC addresses is redundant if serial numbers are provided | ||
| 34 | * Establish expectations for what "ready to commission" means by sharing the [[site readiness checklist>>doc:SHOWRUNNER™ Setup Guide.SHOWRUNNER™ Installation Guide.Preparation.Site Readiness Checklist.WebHome]] |
