2. 10. 1 Before Applying Power
Verify that all safety precautions are taken. Make all connections to the unit before
applying power. Note the external markings described under
Front and Rear Panel
Symbols on page 16 .
The Mains wiring and connectors shall be compatible with the
connector used in the premise electrical system. Failure to ensure
adequate earth grounding by not using the correct components
may cause product damage and serious injury.
2. 10. 2 Ground the Instrument
These products must be used in a normal condition (all means for
protection are intact).
This is a Safety Protection Class I Product (provided with a
protective earthing ground incorporated in the power cord). The
mains plug shall only be inserted in a socket outlet provided with a
protective earth contact. Any interruption of the protective
conductor inside or outside of the product is likely to make the
product dangerous. Intentional interruption is prohibited.
The M1740A mmWave Transceiver does not have an AC power connection. It is
powered by a DC voltage from the E7770A CIU; this voltage is supplied over the RF
Cable Assembly to the LO/Pwr/Ctrl/IF In connector. The DC supply does not
represent a risk of personal injury.
The RF Cable Assembly should not be connected to, or
disconnected from, the M1740A mmWave Transceiver while it is
suppling DC power from the E7770A CIU. This connection should
be made only when the E7770A CIU is powered off, or the cable is
not connected to the E7770A CIU. If the LED status indicator on
the front of the M1740A is lit, this indicates that it is powered up
and the cable should not be disconnected.
When the M1740A mmWave Transceiver is used in connection with the E7770A CIU,
use only the RF Cable Assembly that was supplied with the M1740A to connect it with
the other instrument and connect it only to the mmW ports on that instrument.
