Grounding The ML2400A Series Power Meter must be properly
grounded. Failure to ground the instrument could
be hazardous to operating personnel. The meter is
supplied with a three-conductor power cord. The in-
strument is properly grounded during AC line op-
eration when the plug is connected to a properly
installed three-prong receptacle. A grounding termi-
nal is provided on the rear panel to ground the unit
during operation from a DC supply.

ENVIRONMENTAL
REQUIREMENTS
The ML2400A Series Power Meter is designed to operate within the tempera-
ture range of 0 to 50° C with a maximum humidity of 90% at 40° C,
non-condensing. Full accuracy is specified at 5 to 35° C.
Although not recommended, operation in temperatures to –20° C
is possible. At these temperatures, however, the liquid crystal display 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 ML2400A Series Power Meter can be ordered with rack mounting hard-
ware that allows the unit to be mounted into a standard equipment rack.
There are two rack mount option kits available:
q
The ML2400A-01 Rack Mount option allows the installation of a
single ML2400A in either the left or right side rack position.
q
The ML2400A-03 Rack Mount option allows side-by-side mount-
ing of two ML2400A 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.
