Installing PWRcell Battery
22 Installation Manual for Generac PWRcell Battery
To install REbus wiring:
1. See Figure 4-11. Install REbus conductors to their
terminal blocks: RE+ to red (B), RE- to black (A).
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 30 A REbus DC disconnect.
5. Secure equipment grounding conductor to the
PWRcell Inverter ground bar.
Figure 4-11. REbus Wiring
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 50 V.
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:
NOTE: Mark or flag all conductors as appropriate.
Remote Shutdown Switch Connec-
tions
NOTE: See Figure 4-12. The STOP terminals ship with
a 14 AWG jumper (A) installed. Remove this jumper
before installing an external shutdown switch.
Figure 4-12. Remove Jumper
See Figure 4-13. Connect the wiring (B) to the external
shutdown switch (field supplied) to battery STOP termi-
nals. The STOP Terminals accept 20 to 12 AWG, solid or
stranded wire. As shown, 14 AWG THWN (600 V) wiring
can be used and run in the same conduit as the REbus
wires.
Figure 4-13. Connect To Remote Shutdown Switch
NOTE: Select a code compliant switch rated for STOP
circuit voltage of 12 VDC minimum and current greater
than or equal to 5 mA. Switch must be listed and meet
the requirements of Article 404 of NFPA 70. A suitable
choice is Leviton 12021-2I Single-Pole Toggle Switch, 3
A, 24 V AC/DC.
