1336 PLUS-6.16 - September, 2001
Introduction 1-5
Drive Rating Qualifications
Several factors can affect drive rating. If more than one factor exists, 
derating percentages must be multiplied. For example, if a 14-amp drive is 
installed at a 2km (6,600 ft.) altitude and has a 2% high-input line voltage, 
the actual amp rating is:
14 x 94% altitude derating x 96% high-input line derating = 12.6 amps.
User Supplied Enclosures
1336 PLUS II drives installed in user supplied enclosures may be mounted 
within an enclosure or may be mounted to allow the heat sink
to extend 
outside the enclosure
. 
Use the information in the 1336 PLUS II User 
Manual (1336 PLUS-5.3) to help determine if a possible enclosure sizing or 
derating problem exists.
Conventions
To help differentiate parameter names and display text in this manual, the 
following conventions will be used.
• Parameter Names will appear in [brackets].
• Display Text will appear in “quotes”.
The following is a list of conventions used throughout this manual, and 
definitions of the conventions. For a list of terminology and definitions, 
refer to the Glossary in the back of this manual.
Auxiliary Input
The Auxiliary Input is a terminal connection on the Control Interface 
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 
AuxiliaryFault.
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.
