Installation Manual -- Version 5.1 (4/09)

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.
H2 ELECTRICAL INSTALLATION
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 power
module and booster pump motors 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 cables must be kept separate
from the motor power cables or any other high power
wiring. However, the resolver cables 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.
H2.1 Motor Power Cable
The standard cable consists of 4 conductor with an overall foil
shield. For the Power Module (½D or D), each individual wire is 16
AWG. The wire for the Booster Pump is 10 AWG. Maximum length
of cable run is 700 ft.
SHOCK HAZARD
Hazardous voltage levels are present in the
motor power cable. Insure that the electrical
power to the drive is off before connecting
the motor power cable.
