Note On Dc Wiring And The Nec; Remote Shutdown Switch Connections (If Equipped) - Generac Power Systems PWRcell M3 Installation Manual

To install REbus wiring:
1. See 4-9. Install REbus conductors to their
Figure
terminal blocks: RE+ to red (A), RE- to blue (B).
2. Install equipment grounding conductor to green ter-
minal block (C).
3. If required, route field wiring conductors through
the grommet wiring chase baffle (D).
NOTE: Do not route wires around the baffle.
4. At the PWRcell Inverter, install RE+ and RE- con-
ductors to any unused 30A REbus DC disconnect.
5. Secure equipment grounding conductor to the
PWRcell Inverter ground bar.

Note on DC Wiring and the NEC

Some electricians or installers may be unfamiliar with DC
wiring in a residential setting. Note the following:
•
NEC 215.12(C)(2) for correct DC wiring coloring.
•
NEC 210.5(C)(2) for identification of DC conduc-
tors carrying more than 50V.
Always adhere to applicable codes when marking and
installing DC conductors.
See Table 4-2. For all REbus DC wiring observe the fol-
lowing coloring convention:
Table 4-2.
