3–6 LT Series User Manual
• To prevent the Ring Terminals
*1
from short-circuiting when the terminal
block attachment screws are loosened, use sleeve-type Ring Terminals.
• When the FG terminal is connected, be sure that the wire is grounded.
Not grounding the LT unit will result in excessive noise. Use your
country’s applicable standard for grounding.
Section 3.2.2 – “Grounding”
• Whenever possible, use thick wires (max. 2mm
2
) for power
terminals, and twist the exposed wire ends when connect-
ing the Ring Terminals.
• Use crimp-on type Ring Terminals in the following sizes:
• To avoid electrical shock, be sure the power cord is un-
plugged from the power outlet when connecting the
power terminals to the LT unit.
• The LT requires a DC 24V power supply. If the power
supply does not match the model, both the power sup-
ply and LT unit will be damaged.
• Reattach the LT Terminal Strip’s clear plastic cover
after the wiring is completed. If the cover is not in-
stalled, it may cause an electrical shock.
• Since the LT is not equipped with the power switch,
be sure to connect a breaker type switch to the LT’s
power code.
