Anritsu ML2430A - Manual (Page 15)

Fuses The ML2430A Series Power Meter AC and DC input
lines are protected by internally mounted fuses. These
fuses should only be changed by qualified service per-
sonnel. Replace only with fuses of the same type and
rating (AC fuse is 2A, 250V, slow-blow; DC fuse is 3A,
125V, slow-blow).
Grounding The ML2430A Series Power Meter must be properly
grounded. Failure to ground the instrument could be
hazardous to operating personnel. The meter is sup-
plied with a three-conductor power cord. The instru-
ment is properly grounded during AC line operation
when the plug is connected to a properly installed
three-prong receptacle. A grounding terminal is pro-
vided on the rear panel to ground the unit during op-
eration from a DC supply.

ENVIRONMENTAL
REQUIREMENTS The ML2430A Series Power Meter is designed to operate within the tem-
perature range of 0 to 50° C (32 to 122° F) with a maximum humidity of
90% at 40° C (104° F), non-condensing. Full accuracy is specified at 5 to
35° C (23 to 95° F).
Although not recommended, operation in temperatures to –20° C
(–4° F) is possible. At these temperatures, however, the liquid crystal dis-
play may exhibit excessively slow response. The soft sided carry case
(part number D41310) and optional front panel cover (option ML2400A-
12) can be used to help retain internally generated heat and may improve
response.

RACK MOUNTING The ML2430A Series Power Meter can be ordered with rack mounting
hardware that allows the unit to be mounted into a standard 19-inch
equipment rack. There are two rack mount option kits available:
q The ML2400A-01 Rack Mount option allows the installation of a sin-
gle ML2430A in either the left or right side rack position.
q The ML2400A-03 Rack Mount option allows side-by-side mounting
of two ML2430A Power Meters.
The Power Meter itself must be ordered from the factory as a rack
mount-ready unit. As such, it will be fitted with rack mount top and bottom
cases. These cases have extra mounting holes so that the rack mount kits
can be installed. Instructions for installing the rack mount kits follow.
ML2400A-01 Rack
Mount Installation
This section describes the assembly procedure for fitting a single ML2430A
Power Meter (PM) unit into an instrument rack. The PM must be fitted with rack
mount top and bottom covers before the rack mount kit can be fitted. The proce-
dure involves fitting the support bracket to the PM. The PM can then be loaded
and secured in the rack position desired.
