AC and DC Power Connections
Refer to Figures 3-1 and 3-3.
WARNING: Do not touch any circuit board, power device or electrical
connection before you first ensure that power has been
disconnected and there is no high voltage present from this
equipment or other equipment to which it is connected. Electrical
shock can cause serious or fatal injury.
1.
Connect the single phase incoming power wires from the protection devices to
the control terminal X1 pins L and N. Torque as specified.
2.
Connect earth ground (plant ground) to control terminal X1 pin PE.
Torque as specified.
Motor Connections
A motor circuit contactor (M-Contactor shown in Figure 3-1) is recommended and should
be installed to provide a positive disconnect of the motor from the control. This ensures
that the motor shaft will not rotate and cause damage or injury. The M-contactor should
open the Enable line (J1B pin 8) 20 msec before the main M-Contacts open. This will
prevent contact arcing and allows use of IEC rated contacts.
1.
Connect the “U” terminal of the 29M to the U motor lead.
2.
Connect the “V” terminal of the 29M to the V motor lead.
3.
Connect the “W” terminal of the 29M to the W motor lead.
4.
Connect the “PE” terminal of the 29M to motor ground (G).
Dynamic Brake Resistor
An external DB (Dynamic Brake) resistor must be installed to dissipate excess power
from the DC bus during motor deceleration operations.
WARNING: A DB Resistor may generate enough heat to ignite combustible
materials. To avoid fire hazard, keep all combustible materials and
flammable vapors away from brake resistors.
1.
Mount the DB resistor near the top of the enclosure.
2.
Connect one wire from the DB resistor to terminal DB+ of the control.
3.
Connect the other wire from the DB resistor to terminal DB– of the control.
Note: For selection of the DB resistor, refer to the Specifications located in Section 7
of this manual.
