Low-Voltage Wiring
Figure 2 shows the P266 Series control features under
the housing cover and the low-voltage wiring diagrams
for the P266A, P266B, P266C, and P266E Type control
models.
High-Voltage Wiring
Figure 3 shows the high-voltage wiring diagrams for
the P266A, P266B, and P266C Type control models.
Figure 4 show the high-voltage wiring diagrams for the
P266E Type control models.
Use Table 1 to determine the high-voltage wiring
options available for P266A, P266B, P266C, and
P266E Type control models.
IMPORTANT:
The L2/N terminal must be
connected to line voltage in order for a P266 Series
control to comply with the FCC and IEC Class B
radio frequency interference emissions limit.
