Schneider XW Aux Port Technical Reference

[oblongataman]

I looked in the Schneider reference materials and unfortunately came up short. The installer manual and the user manual reference the Auxiliary (Aux) Port on the bottom of the Conext XW Pro and similar XW and XW+ units but do not specify the type and spec for the connector on the interface board.

The male connector on the interface board measures 18.7 mm from side to side and 7.2 mm high. This matches with spec for terminal block connectors with a pitch of 3.5 mm (Pitch x N + 1.2).



These can be found through several outlets and may also be referred to as terminal block connectors or phoenix connectors.

And since you are here looking for info on the Aux connector, here is the pinout info from the installer manual:

Pin	Reference	Name	Function
JU-1	AUX+12V	+12 V User Voltage Supply	+12 VDC Voltage source: 250 mA maximum
JU-2	AUX-RPO	Remote Power Off	Remote Power Off Logic Level: Active Low. Activating this signal shuts down system operation
JU-3	AUX-COM	Common Ground Reference	Return Common Ground Reference for 12 V, Remote Power Off signals
JU-4	EXT_TS_OUT	External Transfer switch: Output signal	Open collector type drive circuit (30V/0.5A max)
JU-5	EXT_TS_IN	External Transfer switch: Input signal	External Transfer switch: Low signal range: (0-5V) High signal range:10-28V with the consumption of 8mA@12V and 10mA@24V

I hope this helps save someone some time in the future.

And since we are talking about references, here are the front panel screw specs in case anyone needs them in the future:

Larger panel screws for the front:
10-32 x 3/4” Stainless Flat Head
There are five of these screws which hold down the right panel and two on the lower left panel.

Smaller control panel screws:
6-32 x 1/2” Stainless Flat Head
There are four of these for the control panel or SCP replacement.
(This is also the same thread pitch and length of the Schneider DC breakers which mount in the PDP or Mini-PDP but with pan heads.)
