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 Whistle and Tweeter from all voltage sources before it is opened for
servicing.
•
The Whistle and Tweeter 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.
1.2. Cautions
•
The Whistle and Tweeter 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 Whistle and Tweeter to an approved 11 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 Whistle and Tweeter, verify that all safety precautions have
been observed and that the installation procedures in this manual have been followed.
•
Do not clean any of the Whistle and Tweeter drives’ soldering with solvent cleaning
fluids of pH greater than 7 (8 to 14). The solvent corrodes the plastic cover causing
cracks and eventual damage to the drive's PCBs.
Elmo recommends using the cleaning fluid Vigon-EFM which is pH Neutral (7).
