CAUTION: Prior to installation ensure the system configuration and
voltage is equivalent to the JSP Series unit being installed.
Following all applicable National Electrical Code standards as well as state and
local codes, connect phase, neutral* (white wires) and ground (green wires) to
the JSP Series unit .
JSPR units come with 36" of #10AWG conductors . Each phase conductor is
labeled (Phase A, B or C) . Ensure that the conductor lengths are kept as short
and straight as possible . On all high-leg delta systems, the high-leg (208V LN)
must be connected to the Phase B of the SPD . (Color coded orange according
to NEC) .
*The 3-Wire + Ground Delta JSP Series units do not have a neutral conductor.
