(1) Be sure to provide no-fuse breaker (earth leakage
breaker) or switch with fuse of specified capacity for
each controller separately.
(2) To prevent noise from entering from the power cable, if
it is the case, install a filter before the primary input.
Note
• Remarks on "Earth leakage breakers"
Use of earth leakage breakers with medium sensed cur-
rent and high-speed type, if applied, is recommended to
prevent malfunction of the breaker.
• The rated sensed current to prevent malfunction of the
earth leakage breaker is about 100 mA in case of using a
robot only and 200 mA in case of using an external axis
together with a robot. For details and grounding work,
please consult your local electrical engineers.
• For E model of LA and TS series manipulators, use the
attached noise filter without fail. For details of the noise
filter, see the operating instructions of the noise filter.

Connecting to a power facility other than 200 VAC
(For connection to a power facility of 220 VAC,
please refer to section "Using at 220 VAC (For T*/
Y* specification)" on page 25)
• You can use either PE or PEN as ground terminal.
• Do not use the terminal "N" of the power facility, if
any.
• Please prepare a transformer to convert voltage
to 200 VAC at your end.
