WARNING
If you connect or disconnect wiring while the field side power is on,
an electrical arc can occur. This could cause an explosion in
hazardous location installations. Be sure that power is removed or
the area is nonhazardous before proceeding.
ATTENTION
• When connecting wiring, torque terminal screws C, D, E and F
to 0.8 Nm (7 lb-in).
• Power wiring must be less than 10 meters (32.8 ft) in length.
• Do not wire more than 2 conductors on any single terminal.
