Safety

Voltages of up to 130 V are accessible inside the 8743-CL Controller/Driver chassis,
mounts, and Picomotors. DO NOT operate the units with the driver or mount covers
removed. If the wire of a mount or Picomotor is damaged, discontinue use and
return it for repair. If the device is used in a manner not specified by New Focus, the
protection provided by the device may be impaired.
Normally, the case of the Model 8743-CL will rise a few degrees when a Picomotor
is moved. Under conditions of extreme use, meaning long distance moves on one or
more motor channels, the case temperature may rise above what is considered safe
under various international safety conventions. Even after extreme use, the unit's
case temperature will drop to safe levels within a few minutes. The user should not
touch the case immediately following such use. Note that the Model 8743-CL does
contain internal temperature protection circuitry that will shut down the unit when
the case approaches a temperature that could degrade or damage the unit.
CAUTION
The case of the Model 8743-CL Picomotor
Controller/Driver is used to dissipate internally-
generated heat. Blocking the normal convective
airflow around the unit, or thermally insulating the
unit, can result in severe injury, damage to the
product, and/or fire.
