ELECTRICAL SHOCK HAZARD: Access to the inside of the equipment is permitted
only to qualified and authorized service personnel.
Before disconnecting the unit from its cables, verify that the remote unit is
turned OFF. Disconnect the unit from the power line and from all the cables
before removing the cover.
Dangerous high voltages are present inside the Optimux-34 when it is connected
to power. Moreover, under external fault conditions, dangerous high voltages
may appear on the lines connected to the Optimux-34.
Capacitors inside the instruments may still be charged even after the unit has
been disconnected from the supply source.
Any setting or repair of the open unit under voltage should be avoided as much
as possible and, when inevitable, would be carried out only by a skilled technician
who is aware of the hazard involved.
Optimux-34 contains components sensitive to electrostatic discharge (ESD).
To prevent ESD damage, avoid touching the internal components. The E1
channels are not protected against over voltages. Adequate surge suppressors
should be installed into the building wiring.
