2–38 Installation/Wiring
Table 2.F lists the maximum recommended cable length for untermi-
nated cables, since the voltage doubling phenomenon occurs at differ-
ent lengths for different drive ratings. If your installation requires
longer motor cable lengths, a reactor or cable terminator is recom-
mended. Refer to
Table 2.F for frequency, cable length and voltage
restrictions of 1204-TFA1 or 1204-TFB2 terminators.
Optional Output Reactor
Bulletin 1321 Reactors listed in the 1336 PLUS-3.0 Price Sheet can
be used for drive input and output. These reactors are specifically
constructed to accommodate IGBT inverter applications with switch-
ing frequencies up to 20 kHz. They have a UL approved dielectric
strength of 4000 volts, opposed to a normal rating of 2500 volts. The
first two and last two turns of each coil are triple insulated to guard
against insulation breakdown resulting from high dv/dt. When using
motor line reactors, it is recommended that the drive PWM frequency
be set to its lowest value to minimize losses in the reactors.
Important: By using an output reactor the effective motor voltage will
be lower because of the voltage drop across the reactor -
this may also mean a reduction of motor torque.
Selecting/Verifying Fan Voltage 1336 PLUS II D-G Frame drives have cooling fans that utilize a trans-
former to match the input line voltage to the proper fan voltage. If an
input voltage other than the standard 240, 480 or 600V AC is used,
the transformer tap may have to be changed (see below).
1. Ensure that all power has been removed to the drive.
2. Locate the transformer in the lower left corner of the drive
chassis. Note lead placement (tap being used).
3. Determine the correct tap from the following figure and verify.
4. If present tap is incorrect, remove the insulating sleeve from the
correct tap.
5. Remove the wire lead presently connected and place on the
selected tap. Replace the insulating sleeve on the unused tap.
!
ATTENTION: To avoid a shock hazard, assure that all
power to the drive has been removed before proceeding.
