Installation and Wiring
General Input Power Conditioning
The Series D 1333 is suitable for direct connection to a correct voltage AC
power line. There are however certain power line conditions which may
introduce the possibility of drive input power component malfunction. To
reduce the possibility of these malfunctions, a line reactor or isolation type
transformer may be required. If the use of an input transformer is desired,
only an isolation type transformer should be used.
The basic rules for determining if a line reactor or isolation type
transformer is required are as follows:
1. If the AC line supplying the drive has power factor correction capacitors
connected, an AC line reactor or isolation type transformer must be
connected between the capacitor bank and the input to the drive.
2. If the AC line frequently experiences transient power interruptions or
significant voltage spikes, an AC line reactor or isolation type
transformer should be used.
!
ATTENTION: An incorrectly applied or installed system can
result in component damage or reduction in product life. The most
common causes are:
•
Wiring the AC line to the drive output or control terminals.
•
Improper bypass or output circuits.
•
Output circuits which do not connect directly to the motor.
•
Incorrect or inadequate AC supply.
•
Excessive ambient temperature.
Contact Allen–Bradley for assistance with application or wiring.
General Installation
Requirements
Before actual installation, remove all packing material, wedges or braces
from within and around the drive. The 1333 must be installed in an area
where the following installation and environmental guidelines are met.
•
Cabinet mounting must be upright, leaving room for a minimum
clearance of 4 inches (102 mm) on the top and bottom and 2 inches (51
mm) on the sides for proper ventilation.
•
The drive should be easily accessible for maintenance and
troubleshooting.
•
The rated altitude must not exceed 3,300 feet (1,000 meters).
•
Vibration must be within the ratings outlined in Chapter 3 –
Specifications.
•
The ambient atmosphere must not contain volatile or corrosive gas,
vapors or dust.
•
The relative humidity must not exceed 95% for all drive ratings.
•
The ambient temperature for the drive must be kept within –10 to +50
°
C
for all ratings.
