3-4 Installing the Converter
590D DC Digital Converter - HA467078
Minimum Connection Requirements
Note:
Because of the complexity of showing all possible configurations, this Chapter deals only
with a `general purpose’ operation as a basic speed controller. Special wiring options
usually form part of a customer-specific system and connection details will be provided
separately.
The circuit diagram over the page uses bold lines to show the
minimum connection requirements for operating the Converter.
These connection details are highlighted 1 to 9 in the following text
with the symbol opposite. The remaining connection details are not
necessary for a “quick start-up”.
The Converter is using the default Armature Voltage feedback when following the
`minimum connection’ instructions.
IMPORTANT: Indicator lamps, annunciators, etc., for "Drive On" condition should be switched by an
auxiliary contactor of the main contactor, not by the controller auxiliary relay.
To avoid damaging the drive NEVER carry out high voltage resistance or dielectric
strength tests without first completely disconnecting the drive from the circuit being tested.
• Power cables must have a minimum rating of 1.1 x full load current. (1.25 x FLC when
required to comply with UL requirements).
• All incoming main AC power supply connections must be protected with high speed
semiconductor fuses. Refer to Chapter 11: “Technical Specifications” for fuse information.
• The External AC Supply EMC Filter must only be fitted on the mains side of the contactor.
