Warnings

Read all operating instructions before installing, wiring, operating, servicing or
inspecting the MSC-3.
Ensure that the instruction manual is made available to the final user of the product
as well as all personnel involved in any aspect of installation, adjustment or
maintenance.
Your MSC-3 must be applied and installed by a suitably qualified and experienced
electrical tradesperson in accordance with this manual, good engineering practice and
all local rules and regulations
There are hazardous voltages inside the MSC-3 whenever it is connected to an
electrical supply and for some time afterwards.
Before touching anything inside the MSC-3 enclosure or other equipment connected
to the MSC-3 terminals, disconnect all sources of electrical power, wait at least 11
minutes for capacitors within the MSC-3 to discharge to less than 50VDC and then
ensure, by measurement, that there is no hazardous AC or DC voltage present at any
terminal.
The MSC-3 contains high energy circuits that may be hazardous. Do not operate the MSC-3 with the door
open or any part of the enclosure removed.
Do not touch the terminals of the MSC-3 or any associated motor and wiring when it is energised, even if
the MSC-3 and motor are stopped. Electric shock may result.
Do not modify this equipment electrically, mechanically or otherwise. Modification may create safety hazards
as well as voiding the UL listing of models so listed.
The MSC-3 is designed to drive an appropriately rated and otherwise suitable 3 phase induction motor. It is
not suitable for single phase motors or other types of motor or non-motor load. Use with inappropriate load
types may create a safety hazard.
Where the MSC-3 is used as a component part of another product, it is the purchaser's responsibility to
ensure that the final product meets all of the necessary safety, EMC, regulatory, operational and other
requirements for that product. Requirements for the purchaser's final product may be substantially different
to the requirements for stand-alone inverters.
The MSC-3 is intended for use only in fixed wiring applications. It is not intended for use on a flexible supply
cable.
Indicates a condition or practice that, if the warning is not strictly
observed, could result in personal injury or death.
Indicates a condition or practice, if the caution is not strictly observed,
could lead to damage or destruction of equipment or a significant
impairment of proper operation.
This symbol is used to highlight an electrical hazard. Failure to strictly
observe the warning could result in electrocution.
This symbol is used to highlight additional information on the product's
capabilities or a common error in installation, commissioning or
operation.
