For simplicity, reference is made to
the Xpac actuator, L series or R se-
ries. All information is applicable to
the Xpac drives, D series, as well.
X2 ELECTRICAL INSTALLATION
D Power Modules Only
The Xpac consists of two major components, the Electraulic actuator
(cylinder and power module) and the control enclosure. The actua-
tor is installed on the driven device, while the enclosure is remotely
mounted. Connecting them are the motor power and resolver cables,
the feedback cable and the module cable. These cables may not be
run within the same conduit or seal-tite flex hose. Preferred wiring
procedures recommend that power voltages be kept separate from
low level signal lines (resolver and feedback cables). User connec-
tions of electric power and control signals are made at the enclosure.
! IMPORTANT !
•
Motor power and motor resolver cables for the D
power module must be shielded! The shield of each
is connected to the green ground screw on the back
panel of the control enclosure only.
•
The motor resolver signals are low level voltages.
The motor resolver cable must be kept separate
from the motor power cable or any other high power
wiring. However, the resolver cable may be run with
the feedback cable or other low power conductors.
•
Failure to follow the above may inhibit the proper
operation of the actuator.
Drawings D97103, D97096 and D97097 show the connections
between the cable and the control enclosure for ½D, D and 2D
size units. Connections between the cable and the actuator
are shown on drawing S96502.
On 2D size units, there is a junction box located at each mod-
ule. The motor and resolver cables for each motor must be
individually connected. Only one module cable is required; the
heater power is connected between boxes and the solenoid
(on spring fail units only) will only be installed on one module.
