3.2.2 BRU-200 Power Wiring
WARNING
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!
Drawing 9101-1329 illustrates the only required power wiring for a typical installation. 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 AC-AUX auxiliary power input is used
if
DM
logic power must stay
on
when the motor supply is
turned
off
. Absolute positioning with PRO-Series controller kits
is
one
example where this would be
used . Another example would
be
maintaining
DM
logic power so that the
DM
serial interface could
be
used
for
trouble-shooting and diagnostics. The auxiliary AC input must be isolated
or
be
the same phase
as the main AC power
to
the drive module or damage
can
result.
If
multiple BRU-200 drive modules are
used, and AC power is distributed from more than
one
phase, the AC auxiliary input for each drive must
be
from the same phase as the main power for that drive. You may not
use
a single auxiliary AC source
for drives
on
more than one supply phase, even
if
the auxiliary AC source is isolated. See drawing 9101-
1329
for
additional information and examples showing
use
of
the AC-AUX power input.
Selection
of
transformer, line fuses,
and
wire gauges
is
covered
in
drawing 9101-1329.
3.3 Motor Mounting and Wiring
Motor outline drawings
for
the S-Series, F-Series,
and
1-Series motors are shown in drawings 9101-0129,
9101-0332,
and 9101-0130 respectively.
Some motor mounting considerations are as follows:
1
.)
Do not run motor unmounted. Attach all motor cables after motor is mounted.
2.) Mount motor with connectors pointing downward
to
keep liquids flowing away from connectors
and use a drip-loop in cables to allow liquids to flow away from connectors.
3.) Consider motor case temperature
if
necessary to safeguard operator and maintenance staff.
Maximum case temperature is about 1
oooc
(212°F) for a motor used at continuous rating in a
40°C ambient.
Motor connections are shown in Figure
3-1
, Figure
3-2,
and Figure 3-3.
3.4 External Shunt Mounting and Wiring (BRU-200 Option Only}
The External Shunt is designed to be mounted
on
a flat surface. The same mounting restrictions apply
to the External
Shunt as to the BRU-200.
Drawing 9101-1328 shows the External Shunt Resistor dimensions and connection diagram. Note that
the jumper between pins 1 and 2
of
TB2
on
the DM connects the internal shunt resistor when an External
Shunt Resistor
is not being used.
