Note 1. When bundling wires or encasing into conduits (plastic or metal pipes), use the wire of one
upper size.
Note2. In hot environments, such as the temperature in a cabinet, use heat-resistant cable (IV or HIV).
Note3. We provide the following relay cables (3 m/5 m/10 m) for the motor and encoder. Note that the
model varies depending on the actuator used.
◆ For FHA-CminiAC24V type
for a motor: EWC-MB* *
-A06-TN2
for an encoder: EWC-E* *-M06-3M14
◆ For RSF supermini series
for a motor: EWA-M* *-JST04-TN2
for an encoder: EWA-E* *-M09-3M14
(1) Connect the power cable to the HA-680 driver only after
installing the driver on a wall.
(2) Ground the HA-680 driver, to avoid electric shock,
malfunctions caused by external noise, and for the
su
pp
ression of radio noise emissions.
CAUTION
Before connecting the power cable to the HA-680 driver, turn-OFF
the electricity to avoid electric shock.
