* Use a heavy copper braid or wire (cross-sectional area 5.5 mm^ minimum) to ground the
terminal and make it as short as possible as shown in Figure 5.1 for grounding.
Also, Avoid a common ground where earth current may flow. (An independent ground is
preferable.)
* The converter has no power switch. Install the power switch at the system side. Be sure to use a
double-pole/single-throw (both disconnection) wiring breaker.
