0-10V Cable Splicing Above Ceiling

I have a quick question, where 0-10V cabling was installed after the fact for different light fixtures in a commercial application an 18/2C was pulled and terminated. This however is pulled and terminated openly into a power pack. The 120V side of the power pack of course is within a 4 Sq box while the 0-10V cable is wire tied to the exterior of the conduit but terminated it open splices (wirenuts) into the LV side of the power pack. Is there a code I can cite for that being allowed by the NEC?

Any assistance would be greatly appreciated. Thanks in advance!

Is the 0-10v cable come from a class2 power supply?
 
There are vasiour switches in place Wattstopper DW-311, some Occ Sensors DT-200, DT-300.

But it routes through a Universal Voltage Power Pack - Wattstopper BZ-50

Power Pack, 120-277V, 50/60Hz, 24VDC, 225mA, Wire Connector | Power Packs | Occupancy and Vacancy Sensors | Lighting Controls and Systems

The BZ-50 Universal Voltage Power Pack provides 24 VDC operating voltage to Wattstopper’s low-voltage occupancy sensors. This device is constructed with environmentally friendly materials and is RoHS-compliant.

Essentially the 0-10V is derived at the switch for dimming but the occupancy sensors also have the LV controls that will turn off the fixtures if the devices detects that there is no movement via making and breaking the 120V through the power pack contacts. There are open splices at these power packs that I'm being asked about, I mentioned as long as the open splice side is the LV side then there is no concern as it is Class 2 wiring but they are requesting that I provide them with something that says it is allowable above a drop ceiling.
