Safety instructions
This chapter contains information on safe usage of the NEXUS AM Deactivator. Read
this section carefully as it contains important safety guidelines.
The NEXUS AM Deactivator generates high inducted voltage signals up
to 400VDC. If the housing is opened without disconnecting the mains
power first, a high risk of electric shock is introduced.
Therefore always disconnect the mains power first and wait at least 30
seconds before opening the housing.
1. The NEXUS AM Deactivator must be mounted in such a way that it
’s always
possible to disconnect it from the mains power.
2. Always disconnect the mains power prior to opening the housing.
3. After the mains power has been disconnected, wait at least 30 seconds to allow
the high voltage to discharge.
4. Only open the housing in case:
a. The mains voltage needs to be adjusted from 230VAC (default setting) to
115VAC or vice versa. Use switch SW1 to change the mains voltage
setting.
b. The device is not working and one of the internal fuses needs to be
checked or replaced.
c. The device is not working and the antenna connection needs to be
checked.
d. The battery for the internal clock needs to be replaced.
5. Do not place magnetic data holders, like bank cards, credit cards, tapes, etc.,
close to the NEXUS AM Deactivator, because the magnetic field will destroy the
information that is stored on the magnetic data holder. Keep these objects at
least 50cm away from the deactivator’s antenna while deactivation is active.

this fuse accordingly when the power input is switched!
2. Internal mains power switch for 230VAC to 115VAC. Make sure to replace the
external fuse accordingly when the power input is switched!
3. Internal fuses F1 (T500mA) and F2 (T500mA)
4. Internal battery CR 1225 (3V lithium)
