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 Tuba from all voltage sources before it is opened for servicing.
•
The Tuba servo drive 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 Tuba servo drive 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.
•
The TUB-x/230 series is designed to operate from a single-phase 115 VAC source or from a
single- or three-phase 230 VAC source.
The TUB-x/460 series is designed to operate from a three-phase 400 or 460 VAC source.
The Tuba can be connected directly to the line voltage. An isolation transformer is not
needed.
•
The Tuba drive must be connected to an approved 24 VDC auxiliary power supply 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 Tuba, 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 Tuba 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).
