8.1 Allowable Voltage Range
The motors for the Paragon compressor are designed to
function in the voltage ranges listed in Table 19.
Table 19 — Compressor Motor Voltage Range
* For Wye connected motors only.
8.2 Electrical Connection Require-
ments
Power Connections
The compressor terminals are copper feed-through pins
with M12 metric threads for all models (except for low-
voltage versions of the 06TU and 06TV model types,
which have M16 metric threads).
Torque specifications are as follows:
• 15 to 20 lb-ft (20-27 Nm) on the TS, TT, TU and TV
compressors with 12 mm pins
• 20 to 25 lb-ft (27-34 Nm) on low voltage (< 375 V) TU
and TV compressors with 16 mm pins
Power wires are connected to the terminal pins using ring
terminals and jam nuts. The power connection system is
designed for nominal line voltages up to
575 volts. The
motor temperature thermistors and a separate 12 mm
grounding lug connection are located in the terminal pin
area. Terminal and sensor pin layout on the compressor
is shown in Fig. 32 and 33.
The Paragon compressor is approved for use with
across-the-line, open, and closed transition Wye-delta
applications.
Across-the-Line Starting
Table 20 shows the wiring configuration for an across-
the-line (XL), delta configuration.
