How to use

Install the keystone module into a compatible keystone plate or a suitably sized cutout in the device housing until it snaps into place or is secured according to the enclosure design. Route and attach the internal DC wiring to the module's rear contacts following the device's wiring conventions and ensuring correct polarity. After installation, connect an appropriate 5.5 x 2.1 mm DC plug from a compatible power adapter to supply power to the device.

Recommendations

Use the module with power supplies and adapters that match the device's voltage and current requirements; verify polarity before connecting. For secure mounting choose a compatible keystone plate or ensure the housing cutout dimensions match the module. Avoid exposing the connector to moisture or corrosive environments to maintain reliable electrical contact.
