Power and signal wires must be routed to the
actuator separately and be either shielded cables
or installed in conductive conduit and/or cable trays.
Shielded, twisted pair cables should be used
for signal connections to avoid being affected by
electrical noise. These signal wires, based on Noise
Susceptibility Level (NSL) per IEEE-518, fall into the
level 1 classification. A braided shield will be more
effective than a wrapped foil shield. Signal wire
shields should be connected to the actuator casting
grounding screw. If grounding at the signal source
is required, then the shield should not be grounded
at the drive. Raceways such as conduits and trays
have to be grounded at both ends to properly meet
immunity requirements.
A large, clearly labeled terminal block in the
actuator is enclosed in a separate, gasketed metal
enclosure. Terminals will accommodate up to 12
AWG (3.31 mm
2
) wiring.
CAUTION
Always close covers immediately
after installation or service to prevent
moisture or other foreign matter
from entering the actuator.
Refer to the wiring diagram furnished with your
Beck actuator for proper AC power and signal
connections. It is advisable to provide normal short
circuit protection on the AC power line. A copy of
the wiring diagram is shipped with each actuator
and is fastened to the inside of the terminal block
cover. If there is no wiring diagram available, you
may obtain a copy from Beck by providing the serial
number of your drive.
Your Beck actuator has been supplied to match
the signal source in your control loop. If it does not
match, a 250 ohm input resistor may be added or
removed to obtain the proper match. Consult the
factory for details.
For maximum safety, and to comply with
national and international standards, the Beck
actuator body is required to be grounded. Use
one of the two grounding terminals in the wiring
compartment of the actuator to make this
connection. Wire size 12 AWG (3.31 mm
2
) is
recommended for this purpose.
CONDUIT ENTRIES
Conduits are provided for power and signal
wiring. Temporary plugs are installed in the
conduits at the factory for shipping only and are
not intended for permanent use. Prior to actuator
operation, all conduit entrances must be properly
sealed in accordance with National Standards or
Regulatory Authorities.
SAFETY PRECAUTIONS
WARNING
Installation and service instructions
are for use by qualified personnel
only. To avoid injury and electric
shock, do not perform any servicing
other than that contained in this
manual. Please read and understand
the appropriate sections in this
manual before attempting to install
or operate your drive.
CAUTION
Hot surfaces! Surfaces of equipment
may be at an elevated temperature
depending on operating conditions
and environment. Allow to cool
before servicing.
STORAGE INFORMATION
Beck actuators should be stored in their shipping
cartons in a clean, dry area.
If it is necessary to store actuators outdoors for
a long period of time, they should be stored above
ground and covered with a waterproof cover. Do not
stack cartons. Stored actuators should be checked
periodically to ensure no condensation has formed
in electronic and terminal compartments. Moisture
damage while in storage is not covered by warranty.
UNPACKING
Group 42 actuators are shipped in standardized
cardboard shipping containers and secured to a
wooden platform.
INSTALLATION—ELECTRICAL
NOTE: All Beck actuators are shipped from
the factory ready for installation; no electrical
adjustments are required before placing them
in operation. Each actuator is set up and
calibrated to the customer’s specifications
that were written into the equipment order.
Two N.P.T. conduit connections are provided for
power and signal wiring to the drive. One 3/4" conduit
is provided for signal wiring connections, and the
other 3/4" conduit is provided for power and auxiliary
switch connections. A sealant must be used on
threaded conduit connections to keep moisture out.
Conduits should be routed from below the actuator so
that condensation and other contaminants entering
the conduit cannot enter the drive.
