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.
•
Disconnect the Bell from all voltage sources before it is opened for servicing.
•
The Bell stepper 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). It is recommended to measure
the electrical contact points with a meter before touching the equipment.
1.2. Cautions
•
The Bell servo drive contains 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 to Bell to an approved isolated 24 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 Bell, 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 Bell 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).
