Warning

Caution

Only qualified and authorized service personnel should have access to the inside of the unit.

Disconnect the unit from the power line and from all the cables before removing the cover.

Line voltages are present inside IPmux-1/ 1E when it is connected to power. Moreover, under certain external fault conditions, dangerous voltages may appear on the lines connected to IPmux-1/1E.

Any adjustment, maintenance, and repair of the opened device under voltage should be avoided as much as possible and, when inevitable, should be carried out only by a skilled technician who is aware of the hazards involved. Capacitors inside the device may still be charged even after it has been disconnected from its source of power.

The IPmux-1/1E contains components sensitive to electrostatic discharge (ESD). To prevent ESD damage, avoid touching the internal components, and before moving jumpers, touch the IPmux-1/IPmux-1E rear panel.
