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 SHOWRUNNER™ startups.

7 Pre-construction topics to cover:

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 not** leave copper showing at terminations
16 *** **Do not** use lever-nuts (**do** use wire nuts)
17 *** **Do not** excessively strip back the teal-yellow jacket
18 ** [[Ethernet terminations>>doc:SHOWRUNNER™ Setup Guide.Wiring Guide.Wiring Overview.Ethernet.WebHome]] (where the EC is terminating the Ethernet)
19 *** **Do** use T568B Pin-Out
20 *** **Do not** exceed 100m/328' cable length
21 ** [[Zūm Wired wiring>>doc:SHOWRUNNER™ Setup Guide.Wiring Guide.Wiring Overview.Zūm Net.WebHome]] (for Zūm Wired jobs)
22 *** **Do** follow the same rules as Ethernet for both Zūm Net and Zūm Link terminations/cable length
23 *** **Do not** mix up Zūm Net and Zūm Link cables
24 ** Follow the load schedule
25 * Serial number collection
26 ** SNs should be collected for all networked devices (all Cresnet devices and Zūm Wired devices)
27 *** If possible, SNs should be provided prior to startup. This way they can be put into the configuration prior to arriving on-site
28 ** 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
29 ** 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
30 ** 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
31 * MAC address collection (optional)
32 ** Collecting MAC addresses is redundant if serial numbers are provided
33 * 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]]
