Terminal Block TB1 Power Wiring
Input and output power connections are marked on terminal block TB1, a
ten position terminal block on the drive backpanel. For maintenance and
setup procedures, the drive may be operated without a motor connected.
Important:
1. The 1336 does not provide input power short circuit fusing.
Specifications for the recommended fuse size and type to provide drive
input power protection against short circuits are provided on the
following pages. Branch circuit breakers or disconnect switches cannot
provide this level of protection for drive components.
2. Each Bulletin 1336 must have its own dedicated input and output power
leads. If multiconductor cable is used, separate 3-conductor input and
output cable for each drive must be used.
3. For multimotor operation, the combined total of motor full load current
must not exceed the rated output current of the drive.
4. Verify that the motor windings are properly connected to receive the full
drive output voltage rating.
5. For drive ratings B003-B050 & C003-C050, two ground terminals have
been provided at TB1. Either one of these terminals must be connected
to earth ground or the ground of the building system.
For drive ratings B075-B200 & C075-C200, one ground terminal that
will accept two ground leads has been provided at TB1. Connect this
terminal to earth ground or the ground of the building system.
