Precautions 

1.1 

General Safety Warnings  

 
Observe these general warnings when operating or servicing this system: 

 

Heed all warnings on the unit and in the operating instructions. 

 

Do not use this equipment in or near liquids. 

 

Do not operate this equipment in an explosive atmosphere. 

 

Only plug the controller/driver unit into a grounded power outlet. 

 

Route power cords and cables where they are not likely to be damaged. 

 

Disconnect power before cleaning the controller/driver unit. Do not use 
liquid or aerosol cleaners. 

 

Only qualified service personnel should open the case of the 
controller/driver. There are no user-serviceable components inside unit. 

 

Dangerous voltages associated with the 100-120 V AC power supply are 
present inside controller/driver unit. To avoid injury, do not touch exposed 
connections or components while power is on. 

 

Do not wear rings or wristwatches when troubleshooting electrical 
circuits. 

 

To avoid fire hazard, use only the specified fuse(s) with the correct type 
number, voltage and current ratings. Only qualified personnel should 
replace fuses. 

 

Qualified service personnel should perform a safety check after any 
service. 

 

To prevent damage to the equipment, read the instructions in this manual 
for selection of the proper input voltage. 

 

If the Fast Steering Mirror is used with lasers, avoid looking into the laser 
beam, and take precaution not to aim the laser beam at the eyes of others. 

1.2 General 

Cautions 

 
Observe these cautions when operating or servicing this equipment: 

 

Handle equipment with care, like other delicate electronic equipment. 

 

To prevent damage to equipment when replacing fuses, locate and correct 
the problem that caused the fuse to blow before re-applying power.
