Maintenance
No routine maintenance is required. The motors
are permanently lubricated and all internal gear-
train components are oil-impregnated. Careful
installation will also ensure long term reliability and
performance.
Wiring
Use HSO-22xx
cables to connect
the actuators,
using the modular
connectors, as
shown in the
chart and sample
application below.

NOTE: The transformer must have an internal
circuit breaker such as the XEE-6311-050
or equivalent 2.25 A external fuse in the
secondary circuit!
NOTE: See the table on the left for the maximum
number of actuators that may be daisy
chained for a given cable length. If an
HSO-5010 “Y” connector is used (as shown
below), the total number of actuators is
doubled (with half on each side of the
transformer). The example below shows
12 actuators with HSO-2212 cables and an
HSO-5010.
NOTE: For MEP-4042/4842 specifications,
accessories, and additional important
information, see the data sheet. See also the
sample applications in the data sheets for
the BAC-5841/5842 and BAC-5841-16/5842-
16 of controllers.
