Polarity Reversal and City Tie Module (Model:PR-5100) Terminal Connections
See
Appendix C
on page 37 for module speci
fi
cations. Wire as shown in
Figure 15
below using proper wire gauges. Refer to
LT-877POT for more details.
Note that for use in the USA, the installer
must
add an Atlantic Scienti
fi
c (Tel. 407-725-8000) Model #24544 Protective Device,
or similar ULI-Listed QVRG Secondary Protector, as shown. For use in Canada, the protective device is still recommended, but
the PR-5100 may be connected directly to polarity reversal and city tie wiring.
If UDACT-9100 and PR-5100 are used then
Protector not needed. UDACT-9100 has integral protector and PR-5100 is plugged into it.
Notes:
The terminal blocks are “depluggable” for ease of wiring.
•
The city tie interface is
•
not
power limited.
Use either the PR-5100’s City Tie or Reverse Polarity Interface Module - not both.
