Power Source

The M8 sensor cannot operate without power. On average, each D5 sensor uses up to
18 watts of power when it is spinning. Here are some options related to power.

Proper Disconnect

Providing power that fails to meet the specifications in Table 2 may damage the M8 sensor system.
Disconnect from power properly:
NO: Never unplug the cord at the M8 sensor's ferrule power connector (Figure 14 right) or toggle a
connected power strip's on/off switch because the current still latent in the cord can shock the sensor.
YES: Instead, unplug the sensor at the power source (wall outlet or power strip, for example) or at the
M19 connector (Figure 14 left) or simply reboot via the web server's Reboot tab (page 58).

Power Supply

Quanergy does not provide a power supply with
the standard sensor system, but you may purchase
a 120 VAC to 24 VDC power adapter from
Quanergy as shown in Figure 3, which comes
with its own power cable to connect the sensor to
an outlet.
For development purposes, users may provide power via an appropriate power adapter as
specified in Table 2. Make sure the power adapter includes a power indicator (such as the
LED shown in Figure 3). This helps you confirm whether power is off, on (glowing steadily),
or unreliable/intermittent (blinking). This feedback can be important for your support
representative to help you if troubleshooting becomes necessary.
