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-XLT1 when it is
connected to power. Moreover, under external fault conditions, dangerous
high voltages may appear on the lines connected to the Optimux-XLT1.
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.
The Optimux-XLT1 contains components sensitive to electrostatic discharge (ESD).
To prevent ESD damage, avoid touching the internal components. Before moving
jumpers, touch the Optimux-XLT1 frame.
