WIRING
CAUTION
Disconnect power supply before wiring to prevent
electrical shock or equipment damage.
All wiring must comply with local electrical codes,
ordinances and regulations. The ML6185 is designed for
use with a Class 2 power supply. Voltage and frequency of
the transformer used must correspond with the characteris-
tics of the motor and those of the power supply. See Fig. 8
for a typical wiring connection.
The ML6185 has an aluminum die cast housing with
two integral cast bosses on the end of the device, tapped for
1/2 in. conduit fittings. Some models are shipped with a
water seal in the conduit opening. When conduit is needed,
remove the seal before routing the cable.
ML6185 models with Factory-mounted Auxiliary
Switches (See Fig. 9)
ML6185C,F models have two nonadjustable line volt-
age rated spdt auxiliary switches with switches factory set
to make common to normally open at 12
°
and 82
°
rotation
from the counterclockwise stop. See Fig. 9.
IMPORTANT: Actuators driving in parallel may not be
synchronized with each other. In normal operation, if
all actuators are driven to the fully open or fully closed
position, the actuators will again be synchronized.
