SECTION Ill-INSTALLATION
3.1 Mounting the Power Supply and Drive Modules
The BRU-500 power supply and drive modules and BRU-200 drive modules are designed for simple
installation
on
a flat surface such
as
the back wall or plate of
an
enclosure. The environment
in
the
enclosure must
be
clean
and
free
of
oil mist, coolant mist, conductive particles, and corrosive chemicals.
For industrial applications, a NEMA
12
or
equivalent enclosure
is
recommended. The enclosure must
also
be
properly sized (and ventilated
if
required) to insure that the BRU-500 and BRU-200 maximum
ambient temperature is not exceeded.
Drawings
91
01-0409 and
91
01-0410 illustrates a typical BRU-500 installation showing space
requirements between modules for cover removal
and
around modules for wiring and air flow. The
power supply module should
be
centrally located to minimize the distance between it and the drive
modules. It is also recommended that the higher current rating drive modules
be
located closest to the
power supply module.

9101-1300 shows the BRU-200 drive module dimensions including space
requ
irements around
the drive module for wiring and air flow.

DANGER OF ELECTRICAL SHOCK OR BURN. ONLY QUALIFIED
INDIVIDUALS SHOULD WORK ON THIS EQUIPMENT.
DISCONNECT
ALL
POWER BEFORE WORKING ON
EQUIPMENT. DANGEROUS VOLTAGES MAY EXIST AFTER
POWER IS REMOVED! CHECK

EACH TIME POWER
IS
REMOVED BEFORE WORKING ON
EQUIPMENT.
Drawing 9101-0411 illustrates the only required power wiring for a typical four axis installation. The
phasing
of
the three phase input L 1,
L2
, and
L3
to the power supply module is arbitrary, but the DC
bus+
and
- polarities must
be
connected
as
shown
. Also, the phasing of the three phase drive module outputs
R, S, and T must conform to the motor
R,
S,
and
T leads for proper operation. Connect the earth ground
as
shown to insure a safe and proper installation.
The
DC
bus connection wires (substituti
on
not permitted)
are
provided with
each
drive module.
Selection
of
transformer, line fuses,
and
wi
re
gauges is covered
in
drawing 9101-0411 . The optional
auxiliary power supply wiring is covered
in
drawing 9101-0134.
