1.1. Warnings
•
To avoid electric arcing and hazards to personnel or electrical damage, never
connect/disconnect any plug or cable from 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 DC Whistle from all voltage sources before it is opened for servicing.
•
The DC Whistle contains 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 DC Whistle contains hot surfaces and electrically-charged components during
operation.
•
The maximum AC/DC power supply connected to the instrument must comply with the
parameters outlined in this guide. Furthermore, the power supply must be isolated from
hazardous live voltages using reinforced or double insulation in accordance to approved
safety standards.
•
When connecting the DC Whistle to an approved 11 to 95 VDC (8.5 to 67 VAC) auxiliary
power supply, connect it through a line that is isolated from hazardous live voltages using
reinforced or double insulation in accordance with approved safety standards.
•
Before switching on the DC Whistle, 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 DC Whistle drive's 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).
