■ Notes on Wiring the Main Circuit Terminal Block of Models 2011 to 2059 and 4005 to 4065
Read these safety messages and notes before you wire the main circuit terminal block.
WARNING
Fire Hazard. Do not use bent or crushed wires. Remove the damaged end of the wire before you use it. Incorrect
connections can cause death or serious injury from fire.
WARNING
Fire Hazard. If you use stranded wire, make sure that all of the wire strands are in the connection. Also, do not
twist the stranded wire too much. Incorrect connections can cause death or serious injury from fire.
NOTICE
Do not solder stranded wire. Soldered wire connections can become loose over time and cause unsatisfactory
drive performance.
NOTICE
If you use power tools to tighten the terminal screws, use a low speed setting (300 min
-1
(r/min) to 400 min
-1
(r/
min)). High speeds can cause damage to the terminal screws.
NOTICE
Do not tighten the terminal screws at an angle of 5 degrees or more. Incorrect positioning can cause damage to
the terminal screws.
