ENVIROSTART MEC, SS & DVPR INSTALLATION
THE FOLLOWING DETAIL APPLIES TO ALL ENVIROSTART UNITS
PRIOR TO INSTALLATION
Carefully remove the EnviroStart from the packaging and check that the parts supplied correspond with your order.
Check
that
the
Voltage
,
Current
and
kW
ratings of the EnviroStart corresponds with the motor nameplate details.
Check that there are no loose parts or loose objects within the EnviroStart unit.
Check sufficient space exists to correctly install the EnviroStart.
Check you have sufficient tools to correctly install the EnviroStart.
MECHANICAL INSTALLATION
Unless the EnviroStart is fitted within a suitable enclosure the following should be avoided.
1.
Exposure to rain, spray or wet areas.
2.
Exposure to explosive and/or corrosive atmospheres.
3.
Atmospheres containing a high proportion of conductive dust.
4.
Extremes of temperature and/or humidity beyond specified limits.
WALL MOUNTING
Fix the EnviroStart to a flat vertical surface using the mounting holes provided using adequately sized mounting bolts.
Care should be taken to ensure the orientation of the EnviroStart is correct and a gap of 100mm is maintained above and below the EnviroStart.
This is to ensure a safe exit path for the heat generated by the semiconductors within EnviroStart.

ee section on cooling in the Installation and Commissioning Guide.
ELECTRICAL INSTALLATION
INPUT/OUTPUT CONTROL CONNECTIONS
To avoid ‘ pick up’ it is good practice to keep all control connections as short as possible
and to run them separately from the main motor cables. If isolation and screening cannot be guaranteed an interposing relay fitted with suitable
suppression must be used, this should be mounted as close to the EnviroStart as possible.
POWER FACTOR CORRECTION CAPACITORS
Power factor correction capacitors, if fitted, should be connected to the live side of K1
and switched in or out before starting EnviroStart.
NEVER CONNECT POWER FACTOR CORRECTION CAPACITORS TO THE
OUTPUT TERMINALS OF THE ENVIROSTART,
this will cause damage to the unit.
ADDITIONAL EQUIPMENT
all necessary electrical connections for mains, earth and control wiring are provided for in the EnviroStart unit,
however the following additional components may be required, isolator; cable protection fuses; AC3, (three phase AC), rated contactor; motor
overloads etcetera depending upon the wiring configuration and local regulations.
FUSE PROTECTION
The mains supply and the control supply each require fuse protection. The installer should always fuse the mains
supply with
motor rated fuses
before the input to the EnviroStart.
THE FOLLOWING DETAIL APPLIES ONLY TO THREE PHASE SYSTEMS
ENVIROSTART MAINS CONNECTION FOR STAR DELTA SYSTEM
The EnviroStart must be fitted between the Isolator and the Line
Contactor with no other circuits connected. Ensure that the feed to the control circuit is maintained. The mains in, is on L1, L2, L3, the feed to
the motor is on U, V, W, these terminals are marked on the EnviroStart
The start signal
MUST
be volt-free and can typically be taken from spare volt-free auxiliary contacts on the Delta Contactor to the EnviroStart
connectors 1 through 4 in accordance with the details contained within the relevant Installation Guide.
On Star Delta systems when there are back pressure switches on the Star Contactor (Compressors etcetera) you should wire the load solenoid of
the (compressor) in series with the top of ramp, normally open contacts on the EnviroStart.
ENVIROSTART MAINS CONNECTION FOR DIRECT ON LINE SYSTEM
The EnviroStart must be fitted between the Contactor and
the motor, put link between 1 and 2 and use the existing start and stop buttons to control the motor. Please ensure the motor is connected in
Delta mode. The mains in, is on L1, L2, L3, the feed to the motor is on U, V, W, these terminals are marked on the EnviroStart.
OVER TEMPERATURE TRIP
On SS and MEC units of 55kW and above the over temperature trip will operate in the event that the heatsink
temperature exceeds 90C. The temperature trip will need to be reset on the PCB in this event. (Please see detail in Installation Guides).
MAINTENANCE
Periodically clean the fans, (if fitted), to ensure free air flow. Check the security of power connections to unit every six
months or more frequently if the unit is in a high vibration environment. Keeping the inside of your unit clean and dust free will enhance its life,
however, it is not necessary for its normal operation.
DEFAULT SWITCH SETTINGS TABLE
EnviroStart is set to the ‘default settings’ before leaving the factory. These settings should be
tried first and further adjustments made only where necessary to fine-tune the performance of the unit.

STARTING AND STOPPING ENVIROSTART UNITS
To start the EnviroStart MEC or SS provide a legitimate start signal to connectors 1 to 4
on the terminal block, EnviroStart should start at the programmed settings. In the case of MEC and SS units the mains supply and the motor must be
present to allow EnviroStart to start. In the case of the DVPR power may be provided to the output terminals even if no load is present.
To stop the EnviroStart open link between terminals 1 to 4, In the case of MEC and SS units, if soft stop is enabled on either unit be aware that the
motor may continue to be powered for a period after the start/run signal has been removed.
Refer to the Full Installation and Commissioning Guide for details of relay operation and specific system function.
THE FOLLOWING DETAIL APPLIES TO BOTH SINGLE AND THREE PHASE SYSTEM
S
COMMISSIONING CHECKS
1.
Ensure that the terminal block is configured correctly and that the cables are all secure and are of the correct rating for the load.
2.
Ensure that ALL DIP switch settings are at Default or configured according to the details contained within the full Installation and
Commissioning Guide.
3.
Ensure that the unit is correctly and safely wired to the load in accordance with the details contained within the full Installation and
Commissioning Guide.
4.
Ensure that any Power Factor Correction Capacitors within the “local” system, (that is, within 20 cable metres of the EnviroStart control), are
connected to the input side of the system Line Contactor and are switched in and out when EnviroStart is NOT running. It is imperative that the
capacitors are out of circuit and isolated from the EnviroStart at the time that the motor is turned off as they can see the thyristors as a low
impedance line to earth and will discharge through them causing severe damage and risk to operator safety.
5.
Ensure that all specifications relating to the product are adhered to especially with regard to starts per hour during commissioning.
STARTING ENVIROSTART FOR THE FIRST TIME
Check that all the pre-commissioning checks have been followed, then initiate the start by linking 1 though 4 as detailed within the Installation and
Commissioning Guide, EnviroStart should power the load smoothly to full power, if starting is not satisfactory then refer to the full Guide.
WARNING
ENVIROSTART MUST BE EARTHED.
CONNECT THE EARTHING STUD WITHIN THE ENVIROSTART UNIT TO A SUITABLE LOW IMPEDANCE EARTH
AS IS REQUIRED BY STATUTORY REGULATIONS COVERING THE INSTALLATION OF ELECTRICAL EQUIPMENT
.
