Nitek VH3251 - Manual (Page 2)

Remove Front Install Cards
Powering the Hub
The VH3200 is powered from a 24VAC wall pack. It uses a maximum of 18VA so several units can be run from a
larger supply. Contact Nitek Tech Support for recommendations.
Installing Cards
Remove the front panel of the VH3200 by pulling on both front knobs. Insert a card between the card guides. Push
the card to the rear until it slides into the edge connector and the front of the card is flush with the front of the
VH3200. Replace the front panel and press the knobs in to lock it in place. Refer to the instruction sheet with each
card for setup of each card.
