Chapter 2 Safety
All statements regarding safety of operation and technical data in this instruction
manual will only apply when the unit is operated correctly.
SHOCK WARNING
HIGH VOLTAGE
To avoid electrical shock and before applying power to your MDT693B or
MDT694B system, make sure that the protective conductor of the 3-conductor
mains power cord is correctly connected to the protective earth contact of the
socket outlet!
Improper grounding can cause electric shock resulting in severe injury or
even death.
Do not operate without the cover installed. Refer servicing to qualified
personnel.
WARNING – HIGH VOLTAGE OUTPUTS
The MDT693B and MDT694B can produce hazardous voltages and currents.
Use CAUTION when operating the MDT693B or MDT694B and handling the
piezo actuators! The piezo elements are electrical capacitors capable of
storing electrical energy over long periods of time. Besides storing charge
from the MDT693B or MDT694B, the piezo can accumulate static charge over
time due to varying storage temperature and/or mechanical loads. To safely
discharge a piezo, connect it to the MDT693B or MDT694B and set the output
voltage to 0 volts.
WARNING
This unit must not be operated in explosive environments.
ATTENTION
Do not obstruct the air ventilation slots in the housing or fan exhaust.
WARNING
Before applying power to your MDT693B or MDT694B system, make sure that
the protective conductor of the 3-conductor mains power cord is correctly
connected to the protective earth contact of the socket outlet! Improper
grounding can cause electric shock resulting in severe injury or even death.
