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).
