1.1.Electrostatic Discharge (ESD)
A sudden discharge of electrostatic electricity can destroy static-sensitive devices or micro
circuitry. Therefore, proper packaging and grounding techniques are necessary precautions
to prevent damage. Always take the following precautions:
1. Transport boards in ESD-safe containers such as boxes or bags.
2. Keep electrostatic sensitive parts in their containers until they arrive at the ESD-safe
workplace.
3. Always be properly grounded when touching a sensitive board, component, or
assembly.
4. Store electrostatic-sensitive boards in protective packaging or on antistatic mats.
1.2.Grounding of the Product
By following the guidelines below, electrostatic damage to the device can be avoided:
1. Always use properly grounded tools and equipment.
2. Use antistatic mats, heel straps, or air ionizers for more protection.
3. Always handle electrostatically sensitive components by their edge or by their
casing.
4. Avoid contact with pins, leads, or circuitry.
5. Turn off power and input signals before connecting test equipment.
6. Keep work area free of non-conductive materials such as ordinary plastic assembly
aids and Styrofoam.
7. Use only field service tools which are conductive, such as cutters, screwdrivers, and
vacuum cleaners.
8. Always place drives and boards PCB-assembly-side down on the foam.

4. System Overview
The TrustBox is a highly scalable and flexible industrial IoT Edge leaf node device. Based on
the latest NXP LS1012A, a 64-bit ARM® v8 network processor series, the new maintenance-
free, fanless, TrustBox was developed as an intelligent IoT leaf node for secure IoT edge
applications.
The TrustBox is one of the first Scalys products which is Microsoft® Azure certified. This
means the hardware is tested and verified and can be integrated into Microsoft® Azure IoT
Services.
The compact TrustBox shows a broad range of interfaces which allow a connection on
various communication levels. For networking functionality, it offers two 1 Gb Ethernet
connections. For local data collection, e.g. link to sensor and machine level, it offers an
internal header to expand connectivity. TrustBox hardware system configuration and the
robust construction with excellent mechanical stability offer the superior qualities of an edge
device designed for operation in industrial environments. It is a passively cooled system
based on a compact aluminum chassis. The rated voltage of the mains (+5V- 12V DC) can
be found on the type label. The type label is located at the bottom side of the device.

5. Thermal behavior of TrustBox
5.1 Convection Cooling Method
The applied cooling method provides adequate cooling of the device during operation and
performs a one-way thermal transfer to the chassis. TrustBox has an integrated heatsink
with heat spreader contact to the casing. The internal heatsink provides heat dissipation
during operation.
To provide sufficient heat dissipation for the cooling of TrustBox, never cover the chassis.
Do not place any objects on the device. Do not place the device under any object blocking
the top surface of TrustBox. Avoid using TrustBox laying upside down, i.e. with the logo
looking downs.
5.2 Maximum Operating Temperature
The maximum system ambient temperature depends mostly on the power consumption of
the processor and which interfaces are used.
