We recommend that you use any of the following standard 2 gang in-wall junction boxes (or their equivalent):
•US-D: 2 gang US electrical junction boxes.
•EU: 2 gang in-wall junction box, with a cut-hole diameter of 2x68mm and depth that can fit in both the device and the
connected cables (DIN 49073).
•UK: 2 gang in-wall junction box (BS 4662), 135x75mm (W, H) and depth that can fit in both the device and the
connected cables.
•EU/UK: 2 gang on-wall junction box (use the recommended Kramer on-wall box available at
www.kramerav.com/product/WP-789R.).
Step 4: Connect the inputs and outputs
Always switch OFF the power on each device before connecting it to your WP-789R. For best results, we recommend that you
always use Kramer high-performance cables to connect AV equipment to the WP-789R.
Wiring the RJ 45 Connectors
It is recommended that the cable ground shielding be
connected/soldered to the connector shield.

Grounding the WP-789R (Optional)
1. Connect the ring tongue terminal to the building grounding point wire (a green-yellow, AWG#18 (0.82mm2) wire,
crimped with a proper hand-tool is recommended).
2. Insert the M3x6 screw through the toothed lock washers and the tongue terminal in the order shown above.
3. Insert the M3x6 screw (with the two toothed lock washers and ring tongue terminal) into the grounding screw hole
and tighten the screw.
Step 5: Connect the power
When accepting power over HDBaseT from a PoE provider (for example, the TP-780T), there is no need to connect the 12V
DC power supply.
Otherwise, connect the 12V power adapter to the device and plug the power supply into the mains electricity.
