•
Ensure that the MVS is completely isolated from the power supply before
attempting any work on the unit.
•
Entry of metal swarf into the cabinet can cause equipment failure.
•
Do not apply voltage to the control input terminals. These are active
24 VDC inputs and must be controlled with potential free circuits.
•
Ensure contacts/switches operating the control inputs are suitable for low
voltage, low current switching (ie gold flash or similar).
