Appendix C: Best Practices
This section describes important concepts which need special attention to achieve a reliable
installation.
Excess Cable Management
During the first prototype system build, it is possible to encounter cable lengths that are too long for
your system. Leaving the excess cable length unmanaged can result in a messy system installation.
If reducing the cable length is not feasible or if there is no time to physically modify the lengths, a
common solution is to wrap the excess cable length in a coil and fasten the wire loop in the cabinet.
This basic tactic has the undesirable effect of creating an air-core transformer which will couple EMI
into the cable extremely well.
The best solution to cable length management is to bundle the excess length in a figure-8 pattern.
This prevents the bundle from turning into an air-core transformer since the direction of current in
one side of the figure-8 turns opposite to the current in the other side. It is recommended to use the
figure-8 method if physically reducing the cable length is not possible.

From time to time Nuvation Energy will make updates to products in response to changes in available
technologies, client requests, emerging energy storage standards, and other industry requirements.
The product specifications in this document, therefore, are subject to change without notice.
