available. When ordering a minute load model, add the suffix A to the
model number (i.e., VB-2211A for example).
2. SC connectors can be connected to VB models.
3. Models with ground terminals are also available. When ordering a ground
terminal model, add the suffix E to the model number (i.e., VB-2211E for
example).

be replaced.
