Caution
Safety Summary
The following general safety precautions must be observed during all phases of
operation, service, and repair of this instrument. Failure to comply with these
precautions or with specific WARNINGS elsewhere in this manual may impair
the protection provided by the equipment. Such noncompliance would also
violate safety standards of design, manufacture, and intended use of the
instrument. Keysight Technologies assumes no liability for the customer’s
failure to comply with these precautions.
Do not exceed the operating input power, voltage, and current level and signal
type appropriate for the instrument being used, refer to your instrument’s
Function Reference.
Electrostatic discharge (ESD) can damage the highly sensitive microcircuits in
your instrument. ESD damage is most likely to occur as the test fixtures are
being connected or disconnected. Protect them from ESD damage by wearing
a grounding strap that provides a high resistance path to ground. Alternatively,
ground yourself to discharge any static charge built-up by touching the outer
shell of any grounded instrument chassis before touching the test port
connectors.
The E5053A complies with INSTALLATION CATEGORY II as well as
POLLUTION DEGREE 2 in IEC61010-1. The E5053A is an INDOOR USE
product.
The LEDs in the E5053A are Class 1 in accordance with IEC60825-1,
CLASS 1 LED PRODUCT
This equipment is MEASUREMENT CATEGORY I (CAT I). Do not use for CAT
II, III, or IV.

Safety Summary
-
• Ground the Instrument
To avoid electric shock, the instrument chassis and cabinet must be
grounded with the supplied power cable’s grounding prong.
• Do NOT Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of inflammable gases or
fumes. Operation of any electrical instrument in such an environment
clearly constitutes a safety hazard.
• Keep Away from Live Circuits
Operators must not remove instrument covers. Component replacement
and internal adjustments must be made by qualified maintenance
personnel. Do not replace components with the power cable connected.
Under certain conditions, dangerous voltage levels may remain even after
the power cable has been disconnected. To avoid injuries, always
disconnect the power and discharge circuits before touching them.
• DO NOT Service or Adjust the Instrument Alone
Do not attempt internal service or adjustment unless another person,
capable of rendering first aid and resuscitation, is present.
• Do NOT Substitute Parts or Modify the Instrument
To avoid the danger of introducing additional hazards, do not install
substitute parts or perform unauthorized modifications to the instrument.
Return the instrument to a Keysight Technologies Sales and Service Office
for service and repair to ensure that safety features are maintained in
operational condition.
• Dangerous Procedure Warnings
Warnings, such as the example below, precede potentially dangerous
procedures throughout this manual. Instructions contained in the warnings
must be followed.
This equipment is tested with stand-alone condition or with the
combination with the accessories supplied by Keysight Technologies
against the requirement of the standards described in the Declaration of
Conformity. If it is used as a system component, compliance of related
regulations and safety requirements are to be confirmed by the builder of
the system.
Dangerous voltage levels, capable of causing death, are present in this
instrument. Use extreme caution when handling, testing, and adjusting
this instrument.

Keysight E5053A Microwave Downconverter 13
Installation
Requirements for installation environment
Heat dissipation clearance
To satisfy the safety, specifications, and measurement accuracy of the product,
you need to keep the temperature around the product within a specific range
by providing proper heat dissipation clearance around the product or by
forcefully air-cooling the inside of the rack. For information on ambient
temperature to satisfy the specifications and measurement accuracy of the
product, refer to the “Specifications and supplemental performance
characteristics” Chapter in the User’s Guide.
When the temperature around the product is kept within the specified
temperature range, the product will comply with the safety standards.
Furthermore, the product will also comply with the safety standards when the
product is installed with clearance for heat dissipation according to Figure 1-2
below.

Providing space to disconnect the power cable’s plug
As described in “Cutting power supply” on page 20, the disconnecting device
(the device to cut the supply of power) of the E5053A is the plug of the power
cable. When installing the E5053A, provide sufficient clearance not to hinder
the operation of disconnecting the plug of the power cable (on the power
outlet side or the E5053A side) in an emergency to cut the supply of power.

Figure 1-4.
Step 1. Remove the trim strips (1) stuck to both the sides of the front panel (stuck to
the frame).
Step 2. Mount the front handles (3) to both the sides of the front panel of the E5053A
with the attached screws.
If a front handle you mounted is damaged, replace it with new one
immediately. If you use a damaged front handle to move/transport the
instrument, the handle may break, which may injure the operator or break
the instrument.

Step 4. Mount the E5053A into the rack.
Mounting rackmount/handle kit (Option 1CP)
The rackmount/handle kit is a kit that contains both the flanges for rackmount
and the front handles for the E5053A. Follow these steps to mount it, referring
to the Figure 1-4.
Step 1. Remove the trim strips (1) stuck to both the sides of the front panel (stuck to
the frame).
Step 2. Mount the front handles (3) and the flanges for rackmount (4) to both the
sides of the front panel of the E5053A with the attached screws.
Step 3. Remove the 4 legs on the bottom of the E5053A (pull up the part with the

Step 4. Mount the E5053A into the rack.
Be sure to use both the front handles and the rack-mounting flanges at the
same time. Do not attempt to install flanges or handles separately with the
hardware provided, since this risks serious electrical damage to the
instrument.

Checking and connecting the power cable
The power cable that comes with the E5053A has a three-wire structure and
one of them is the grounding wire. This power cable grounds the E5053A
through an outlet, protecting the operator from shock hazards.
Step 1. Check the power cable you use for damage.
Step 2. Connect the attached power cable between the power cable receptacle on
the rear panel of the E5053A (see Figure 1-5 on page 18) and a three-pole
outlet whose grounding terminal is grounded securely.
For power cable options, refer to http://www.keysight.com/find/powercords.
Never use a power cable that may be damaged. You may get an electrical
shock.
Securely ground the E5053A with the attached 3-wire power cable with
the grounding wire.
