3 Installation Instructions

Line Voltage Selection
You do not need to set the line voltage, as this is done automatically by the power supply. The monitor
has a wide-range power supply that allows you to operate the monitor from an AC (alternating current)
power source of 100V — 240V (± 10%) and 50/60 Hz (± 5%).
Connecting the Monitor to AC Mains
The monitor is an electrical Class II device in which the protection against electric shock does not rely
on basic insulation and a protective earth conductor, but on double and/or reinforced insulation.
WARNING
•
Always use the supplied power cord with the earthed mains plug to connect the monitor to an
earthed AC mains socket. Never adapt the mains plug from the power supply to fit an unearthed
AC mains socket.
•
The protective earth conductor is required for EMC purposes. It has no protective function
against electric shock! The protection against electric shock in this device is provided by double
and/or reinforced insulation.
•
Do not use AC mains extension cords or multiple portable socket-outlets.
Always ensure that the monitor is positioned so that the AC mains plug is easily accessible, to allow
disconnection of the monitor from the AC mains.
External Power Supply (FM20/30 Battery Option #E25 only)
The external power supply M8023A (option #E25) allows you to operate the fetal monitor from an
AC (alternating current) power source of 100V — 240V (± 10%) and 50/60 Hz (± 5%). If this option
is used, then the M8023A (option #E25) power supply is included for FM20/FM30.
