1.1.  Warnings 
•  To avoid electric arcing and hazards to personnel and electrical contacts, never 
connect/disconnect the servo drive while the power source is on. 
•  Power cables can carry a high voltage, even when the motor is not in motion. Disconnect 
the Hornet and Bee from all voltage sources before it is opened for servicing. 
•  The Hornet and Bee servo drives contain grounding conduits for electric current protection. 
Any disruption to these conduits may cause the instrument to become hot (live) and 
dangerous. 
•  After shutting off the power and removing the power source from your equipment, wait at 
least 1 minute before touching or disconnecting parts of the equipment that are normally 
loaded with electrical charges (such as capacitors or contacts). Measuring the electrical 
contact points with a meter, before touching the equipment, is recommended. 
•  Cleaning after soldering. To avoid damage to the product’s acrylic coating, the Hornet and 
Bee must not be cleaned after soldering with soluble solvents or water-based cleaners. For 
further details see:

1.2.  Cautions 
•  The Hornet and Bee servo drives contain hot surfaces and electrically-charged components 
during operation. 
•  The maximum DC power supply connected to the instrument must comply with the 
parameters outlined in this guide. 
•  When connecting the Hornet and Bee to an approved 12 to 95 VDC auxiliary power supply, 
connect it through a line that is separated from hazardous live voltages using reinforced or 
double insulation in accordance with approved safety standards. 
•  Before switching on the Hornet and Bee, verify that all safety precautions have been 
observed and that the installation procedures in this manual have been followed.
