How to display Displaying labels - created using LabelLayer only at certain scales in ArcGIS API for JavaScript

I am using ESRI Javascript 3.7 framework to develop a map application, in it I am trying to display labels created using LabelLayer at certain scales only, say from 1:1 to 1:500 scale only, how.

How can I achieve this?

I played a little with ScaleDependentRenderer but it results in 2 firebug exceptions. Not sure if the ScaleDependentRenderer is the right answer or not. So, if anyone can help, I would really appreciate.

var occupancyLabelLayer = new esri.layers.LabelLayer({ id: "labels" });
// add the label layer to the map
map.addLayer(occupancyLabelLayer);

var labelField = "FLOOR";
// create a text symbol to define the style of labels

var spaceLabelColor = new dojo.Color("red");
var spaceOccupancyLabel = new esri.symbol.TextSymbol().setColor(spaceLabelColor);
//spaceOccupancyLabel.font.setSize("14pt");
spaceOccupancyLabel.font.setFamily("arial");
var spaceOccupancyLabelRenderer = new esri.renderer.SimpleRenderer(spaceOccupancyLabel);

var spaceLabelScaleDependentRenderer = new ScaleDependentRenderer({
    rendererInfos: [{
        renderer: spaceOccupancyLabelRenderer,
        minScale: 500,
        maxScale: 1
    }]
});

occupancyLabelLayer.addFeatureLayer(featureLayer, spaceLabelScaleDependentRenderer, "${" + labelField + "}");

Firebug Exceptions:

1)exception in animation handler for: onEnd
