SP600 AC Drive User Manual
3.1.1.2 Input Power Conditioning
If any of the following conditions exist, the use of a line reactor or
isolation transformer is recommended.
•
Frequent power outages
•
Ungrounded AC supply source
•
Facility has power factor correction capacitors
•
Input voltage variations exceed drive operating specifications
3.1.1.3 AC Input Phase Selection (60HP and Larger)
Move the “Line Type” jumper as shown in figure 3.2 to select single
or three-phase operation.
Important:
When selecting single-phase operation, input power
must be applied to the R (L1) and S (L2) terminals
only.
3.1.1.4 Selecting/Verifying Fan Voltage (60HP and Larger)
Drives rated 60HP and larger use a transformer to match the input
line voltage to the internal fan voltage. If your line voltage is different
than the voltage class specified on the drive nameplate, it will be
necessary to change the transformer tap as shown in figure 3.2.
Common Bus (DC Input) drives require user supplied 120 or 240V
AC to power the cooling fans. The power source is connected
between “0 VAC” and the terminal corresponding to your source
voltage.
The transformer is located behind the Power Terminal Block in the
area shown in figure 3.2. Access is gained by releasing the terminal
block from the rail. To release terminal block and change tap:
Step 1.
Locate the small metal tab at the bottom of the end block.
Step 2.
Press the tab in and pull the top of the block out. Repeat
for next block if desired.
Step 3.
Select appropriate transformer tap.
Step 4.
Replace block(s) in reverse order.
