For single phase input applications, connect the AC input line to
input terminals (L1) R and (L2) S.

Connection for dynamic brake resistors for all models.
Important:
P52 – [DB Enable] must be enabled for proper
operation. See Appendix A for part numbers.

Bulletin 160 controllers are

and

listed as

motor overload protective devices. An external overload relay is
not required for single motor applications.

Connection for an external capacitor module. Provides extended
ride through capability and improved inherent braking
performance. See Appendix A for part number.

ATTENTION:

The controller is

intended to be commanded by control
input signals that will start and stop the
motor. A device that routinely disconnects
then reapplies line power to the controller
for the purpose of starting and stopping the
motor should not be used. If it is necessary
to use this method for starting and stopping
or if frequent cycling of power is
unavoidable, make sure that it does not
occur more than once a minute.

ATTENTION:

Do not connect power

factor correction capacitors to controller
output terminals T1, T2, and T3 (U, V, and
W) or component damage could occur.

Input Power Conditioning

The controller is suitable for direct connection to
AC power lines within the rated voltage of the
controller (see Appendix A). Listed below are
certain power line conditions which may cause
component damage or reduction in product
life.
If any of the conditions exist as described in
the table below, install “one” of the devices listed
under the heading “Corrective Action” on the line
side of the controller. Important: Only one
device per branch circuit is required. It should be
mounted closest to the branch and sized to handle
the total current of the branch circuit.
