To access the field wiring compartment for power and
signal connections:
1. Remove the 2 screws and cover from the top of
the actuator housing.
2. Pass all customer-supplied wires into the enclo-
sure through the 2 conduit hubs.
WARNING
Equipment Damage
To ensure physical protection as well as
electromagnetic immunity, the use of flexible,
sunlight-resistant, jacketed, metallic, water-
tight conduit is required. The conduit should be
connected to earth ground on both ends.
3. One or both conduit holes may be used when
wiring an actuator.

4. In addition to a grounded conduit, the use of
shielded, twisted-pair cable is strongly recom-
mended for DC power and signal wires. The
shield drain wires should be landed to chas-
sis/earth on both ends of the cable, but ONLY if
a conduit is also grounded on both ends. In other
cases, earth the shields at actuator end only.

Input power

IMPORTANT
Use DC power only.
Use cable rated for the temperatures and voltages
required by the application. Use a gauge of wire to
minimize voltage loss (droop) over long cable runs,
especially at full current load. Ensure that voltage
specifications are met under all conditions.
See Table 2.
A fuse or breaker should be installed at the power
source. If the power supply is not factory-supplied, a
SELV (Safety Extra Low Voltage) rated supply with
regulated output must be provided.
Communication (Modbus over RS-485)
Use appropriate communication cable. A network will
consist of a customer's Modbus master (with
termination) and one or more actuator slaves. See
SLATE documentation for wiring specifics.
NOTE: On commercial models only:
Do not wire the non-isolated common
terminal to the Slate system; leave it
unconnected. Instead, wire the 24V- of the
actuator supply to Pin 2 of the Slate
Sub-Base. If all actuators share the same
supply, only one connection is needed.
Network layouts should be arranged so that
branch/homerun length does not exceed 300 feet for
commercial actuators, or 2000 feet for industrial
actuators.
