8.7 Polarity Reversal and City Tie Module (PR-300) Wiring
Wire the PR-300 Polarity Reversal and City Tie Module (if used) as shown in Figure 16 below.
Power Limited cable type FPL, FPLR or FPLP must be used. For USA installation, the installer
must use Atlantic Scientific (Tel: 407-725-8000), Model #24544 Protective Device, or
similar UL-Listed QVRG secondary protector, as shown. For use in Canada, the Protective
Device is not required but still recommended.
