White Electric | Box Junction Miniature H/Card

Issue:
Lugs availability on the ATV61/71.

Product Line:
Altivar ATV61 and ATV71 drives

Environment:
All

Cause:
Needs to know if the lugs come with the ATV61 or ATV71 drives.

Resolution:
From the installation manuals, the 61/71 products up to the HD75N4 (in 460VAC), HD45M3X (for 230VAC) and HD90Y (600VAC) include terminals. All units above that size (HD90N4, HD55M3X and HC11Y and larger) include bus bar connections. The drives with the terminals are all included in the Low Horsepower manuals, and those with bus bar connections are High Horsepower. Lugs are not included with the High Horsepower drives, and need to be supplied by the installer.

This is true for open style drives. Our enclosed drives will have lugs included.


 

Over the coming months, the terminal connectors supplied with a number of Electrical Accessories will be changing. These changes are:
 

1. The screw type in the connector will suit either a No. 2 Philips Drive or a No 1 Square Drive screwdriver.

 

1. Terminal connectors will now be square wrapper design, ensuring reliable connection.

 

1. All connectors will now be supplied with single screw. This is fully compliant with AS/NZS3000:2007 as per clause (d) below from sub-section 2.9.4. for active, neutral and earth connections.

(d) a neutral conductor used as a combined protective earthing and neutral (PEN) conductor for protective earthing of any portion of an electrical installation, the terminal shall be of a type having—

1. two screws; or
2. one screw with an outside diameter not less than 80% of the tunnel diameter.

 
The terminal connectors being supplied have a screw diameter in excess of 80% of the tunnel diameter which means the single screw connectors can be used for active, neutral and earth connections.
