Read all safety instructions before operating your WOLF ONE system.

Electrical Safety​

Power Requirements​

SpecificationValue
BUS Barrel Port Voltage12-24V DC
BUS Maximum Current2A Fused
USB Power5V via Type-C
Node Power Consumption (Max)2W

Warnings​

Electrical Hazards
  • Do not exceed 24V DC input - Higher voltages may damage the unit or cause fire
  • Use only the supplied power adapter or a compatible 24V DC, 2.5A power source
  • Do not operate with damaged cables - Inspect all cables before use
  • Keep away from water and moisture - The unit is not waterproof
  • Do not open the enclosure - Opening enclosure may void warranty

Grounding​

  • When using multiple power sources for cameras, strobes, and nodes, ground loops may occur
  • If you experience erratic behavior or calibration issues, try:
    • Powering all equipment from the same electrical circuit
    • Using wireless trigger adapters to isolate signals
    • Reducing the number of interconnected cables

Electrostatic Discharge (ESD)​

Before handling the node:

  • Touch a grounded metal object to discharge static
  • Avoid working on carpet or synthetic materials
  • Handle by the enclosure edges, not the ports

Operating Environment​

ConditionSpecification
Operating Temperature0°C to 40°C (32°F to 104°F)
Operating Humidity10% to 80% relative humidity, non-condensing
Intended EnvironmentIndoor use only
Ingress ProtectionNot rated for water or dust ingress
Environmental Requirements
  • Indoor use only - Designed for controlled studio and production environments
  • Not for outdoor use - Not intended for outdoor, wet, or high-condensation locations
  • Avoid direct sunlight for extended periods or your enclosure may become discolored

Cable Safety​

Maximum Cable Lengths​

Cable TypeMaximum LengthNotes
HowlNET (RJ45)100m (328 ft)
USB Type-C3m (10 ft)USB 2.0
Camera cables10m (32 ft)Varies by camera

Cable Handling​

  • Do not bend cables at sharp angles
  • Do not run cables under heavy objects
  • Strain relief: Secure cables to prevent connector stress
  • Disconnect by gripping the connector, not the cable

Firmware Updates​

Firmware Flashing
  • Disconnect 24V bus power before flashing
  • Connect only USB Type-C to the node being flashed
  • Do not disconnect during firmware update
  • A failed update may require factory service

Multi-Node Systems​

When daisy-chaining nodes:

  • Use a single 24V power source for the entire chain
  • Connect HowlNET OUT → HowlNET IN between nodes
  • Ensure adequate power capacity for all nodes

Camera and Strobe Safety​

Camera Port Ratings​

Trigger Outputs (Camera/Mono Ports):

  • Output type: Optically isolated open collector
  • Maximum switching current: 50mA
  • Maximum switching voltage: 24V
  • Maximum power dissipation: 100mW
  • Maximum reverse voltage: 5V
  • No voltage generated by output (requires external pull-up)

Trigger Inputs (Input Port):

  • Input voltage: 3.3V logic (pull-up)
Input Port Warning

DO NOT apply external voltage to input ports

  • Input ports are for signal sensing only
  • Applying external voltage may damage the node

Strobe and Flash Compatibility​

  • Follow your camera manufacturer's safety guidelines
  • Some vintage flash units have high trigger voltages (>12V) - verify compatibility before connecting
  • Allow strobes to fully recycle before triggering

Disposal​

Dispose of electronic equipment according to local regulations. Do not dispose of in household waste.

Emergency Procedures​

If the unit emits smoke, unusual odor, or excessive heat:

  1. Immediately disconnect all power sources
  2. Do not attempt to operate the unit
  3. Contact Arc Eye support

If liquid enters the unit:

  1. Disconnect power immediately
  2. Do not attempt to power on
  3. Allow to dry completely before inspection
  4. Contact Arc Eye support before use
