Prepare the Mounting Location
 The drive must be mounted in a vertical position only.

Installation should be on a suitable flat, flame resistant
surface. Do not mount flammable material close to the drive.
 Refer to Technical Data and ensure the chosen mounting
location is within the drive specification.
 The mounting location should be free from vibration.

Do not mount the drive in any area with excessive humidity,
corrosive airborne chemicals or potentially dangerous dust
particles.
 Avoid mounting close to high heat sources.
 The drive must not be mounted in direct sunlight. If
necessary, install a suitable shade cover.
 The mounting location must be free from frost.
 Do not restrict the flow of air through the drive heatsink.
The drive generates heat which must be naturally allowed
to dissipate. Correct air clearance around the drive must
be observed.
 If the location is subject to wide ambient temperature
and air pressure variation, install a suitable pressure
compensation valve in the drive gland plate.
NOTE If the drive has been in storage for a period longer than 2 years, the DC link capacitors must be reformed. Refer to
online documentation for further information.

 For 1 phase supply (Sizes 1-3 only), the mains power cables should be connected to L1/L, L2/N.
 For 3 phase supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important.
 For compliance with CE and C Tick EMC requirements, refer to online documentation.
 A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the drive
and the AC Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe,
EN60204-1, Safety of machinery).
 The cables should be dimensioned according to any local codes or regulations. Maximum dimensions are given in the
Rating Tables section of this Quick Start Guide.

Short Circuit
Capacity
All drives are suitable for use on a circuit capable of delivering not more than 100kA maximum short-circuit Amperes
symmetrical with the specified maximum supply voltage when protected by Class J fuses.
Mechanical Installation Requirements
All E3 units are intended for installation within controlled environments which meet the condition limits shown in the Environment section of
this Quick Start Guide.
The drive can be operated within an ambient temperature range as stated in the Environment section of this Quick Start Guide.
Electrical Installation Requirements
Incoming power supply connection must be according to the Install the Wiring section of this Quick Start Guide.
Suitable power and motor cables should be selected according to the data shown in Rating Tables section of this Quick Start Guide and
the National Electrical Code or other applicable local codes.
Motor Cable 75°C Copper must be used.
Power cable connections and tightening torques are shown in the Mechanical Dimensions section of this Quick Start Guide.
Integral Solid Sate short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in
accordance with the national electrical code and any additional local codes. Ratings are shown in the Rating Tables section of this Quick
Start Guide.
For Canadian installations transient surge suppression must be installed on the line side of this equipment and shall be rated 480Volt
(phase to ground), 480 Volt (phase to phase), suitable for over voltage category iii and shall provide protection for a rated impulse
withstand voltage peak of 2.5kV.
UL Listed ring terminals / lugs must be used for all bus bar and grounding connections.
General Requirements
The E3 drive provides motor overload protection, set at 150% of full load, in accordance with the National Electrical Code (US).
Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P-60 = 1.
Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information shown in the
Motor Thermistor Connection section of the Quick Start Guide.
UL rated ingress protection (“Type” ) is only met when cables are installed using a UL recognized bushing or fitting for a flexible conduit
system which meets the required level of protection (“Type”).
For conduit installations the conduit entry holes require standard opening to the required sizes specified per the NEC.
Not intended for installation using rigid conduit system.
WARNING: The opening of the branch-circuit protective device may be an indication that a fault has been interrupted. To reduce the
risk of fire or electric shock, current-carrying parts and other components of the controller should be examined and replaced if damaged.
If burnout of the current element of an overload relay occurs, the complete overload relay must be replaced.
ATTENTION: Le déclenchement du dispositif de protection du circuit de dérivation peut être dû à une coupure qui résulte d’un courant
de défaut. Pour limiter le risque d’incendie ou de choc électrique, examiner les pièces porteuses de courant et les autres éléments du
contrôleur et les remplacer s’ils sont endommagés. En cas de grillage de l’élément traversé par le courant dans un relais de surcharge, le
relais tout entier doit être remplacé.

Analog and Digital Input Macro Configurations
Overview
The E3 drive uses a Macro approach to simplify the configuration of the Analog and Digital Inputs. There are two key
parameters which determine the input functions and drive behaviour:
P-12 Selects the main drive control source and determines how the output frequency of the drive is primarily controlled.
P-15 Assigns the Macro function to the analog and digital inputs.
Additional parameters can then be used to further adapt the settings, e.g.
P-16 Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA.
P-30 Determines whether the drive should automatically start following a power on if the Enable Input is present.
P-31
When Keypad Mode is selected, determines at what output frequency / speed the drive should start following the enable
command, and also whether the keypad start key must be pressed or if the Enable input alone should start the drive.
P-47 Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt, 4 – 20mA.
