diagnostics and part replacement.
!ATTENTION: Some printed circuit boards and drive
components may contain hazardous voltage levels.
Remove and lock out power before you disconnect or
reconnect wires, and before you remove or replace
fuses and circuit boards. Verify bus voltage by
measuring the voltage between the Negative Capacitor
Bus and both ends of all three bus fuses. An open fuse
does not show voltage across both ends of the fuse.
Failure to measure voltage at both ends of the fuses
may result in death or serious injury. Refer to Figure
3.5. Do not attempt to service the drive until the bus
voltage has discharged to zero volts.

!ATTENTION: Potentially fatal voltages may result
from improper usage of oscilloscope and other test
equipment. The oscilloscope chassis may be at a
potentially fatal voltage if not properly grounded. If an
oscilloscope is used to measure high voltage
waveforms, use only a dual channel oscilloscope in the
differential mode with X 100 probes. It is
recommended that the oscilloscope be used in the A
minus B Quasi-differential mode with the oscilloscope
chassis correctly grounded to an earth ground.
!ATTENTION: Only personnel familiar with the
1336 IMPACT Adjustable Frequency AC Drive and
associated machinery should plan or implement the
installation, start-up and subsequent maintenance of the
system. Failure to comply may result in personal injury
and/or equipment damage.
!ATTENTION: This assembly contains parts and
sub-assemblies that are sensitive to electrostatic
discharge. Static control precautions are required when
servicing this assembly. Component damage may result
if you ignore electrostatic discharge control procedures.
If you are not familiar with static control procedures,
reference Rockwell Automation Publication
8000-4.5.2, Guarding Against Electrostatic Damage, or
any other applicable ESD protection handbook.
Electrostatic discharge generated by static electricity can damage the
complementary metallic oxide semiconductor devices on various
drive boards. It is recommended that you perform these procedures
to guard against this type of damage when circuit boards are
removed or installed:
•Wear a wrist-type grounding strap that is grounded to the drive
chassis.
•Attach the wrist strap before removing the new circuit board from
the conductive packet.
•Remove boards from the drive and immediately insert them into
their conductive packets.

Configured Options
All H Frame systems are configured, which means that each system
is built and tested to a specific order. Configuration also means that
considerable variation between systems is possible. The variations
are all in the Converter Bay (the cabinet to the right), where power is
converted from an AC input to DC power.
A primary variation between systems is the incoming power
connection. Table P.F lists typical code combinations used to specify
input circuits. Figure P.2 shows a typical Converter Bay.

To help differentiate parameter names and display text from other
text in this manual, the following conventions will be used:
•Parameter Names will appear italicized.
•Display Text will appear in “quotes”.
The following is a list of conventions used throughout this manual,
and definitions of the conventions.
Auxiliary Input
The Auxiliary Input is a terminal connection on the L Option Board.
This connection provides an external input for use as an Auxiliary
Interlock. Unless this interlock is closed, the drive will be faulted
with an Auxiliary Fault.
Auxiliary Interlock
The Auxiliary Interlock is a user supplied circuit consisting of reset,
overload, or other interlocking circuitry. The Interlock is wired to the
drive Auxiliary input.
Bit
A bit is a single character or status point used in programmable
logic. Eight bits form a BYTE, 16 bits form a word. Drive
parameters are actually eight bits or 16 bit words.
Check
To check means to examine either the physical condition of
something or the setting of some control, such as a Parameter.
Checking a drive board or component may also require
measurements and tests.
Connector
A connector connects one drive board to another. Connectors come
in two designs, male and female. Male connectors are stationary and
contain pins, which are sometimes joined by jumpers. Female
connectors are at the ends of wires or ribbon cables and plug into
male connectors.
Conventions

Preface P–9
Publication 1336 IMPACT-6.8– November, 2002
Default
When a drive function defaults, it automatically changes to a
pre-programmed setting.
Enable Input
The Enable Input is a terminal connection on the L Option Board.
This connection provides an external input to enable or disable the
Drive Output section. It must be true to permit the drive to operate.
False
False refers to a logical false state. For instance, an L Option signal
on TB3 is false when the input contact is open or the appropriate
voltage is not applied to the L Option Board.
Jumper
A jumper completes a circuit between two pins within a male
connector on a drive board. In the absence of certain optional
equipment using female connectors, jumpers are applied to certain
pins within a male connector to complete specific and necessary
circuits.
L Option Board
An L Option Board plugs into connectors J7 and J9, located on the
lower portion of the Control Board. This board is identified as L4,
L5, L6, L7E, L8E, or L9E and provides optional control wiring
configurations for a drive.
Parameter
Parameters are programmable drive functions that define various
operating functions or status displays of a drive. Refer to 1336
IMPACT Adjustable Frequency AC Drive User Manual for
parameter details.
Press
Press a button on the Human Interface Module to change parameter
settings and drive functions.

PrefaceP–10
Publication 1336 IMPACT-6.8– November, 2002
True
True refers to a logical true state. For instance, an L Option signal on
TB3 is true when: L4/L7E contact input is closed, L5/L8E input
terminal registers 24V, or L6/L9E input terminal registers 115V AC.
