SERIES EL 070312
These units are zero-clearance stackable, i.e., no top or side ventilation is required when rack
mounting. However, If the unit is rack mounted, or installed within a confined space, care must
be taken that the ambient temperature, which is the temperature of the air immediately sur-
rounding the load, does not rise above the specified limits (see Table 1-2).
2.5 INSTALLATION
WARNING!
The load is very heavy (80 - 90 pounds). Exercise care when lifting,
mounting or otherwise handling this product. It is recommended that
two or more persons handle the electronic load.
2.5.1 RACK MOUNTING
The unit is intended to be either used on a bench or mounted directly in a 19-inch wide rack.
These units are zero-clearance stackable, i.e., no top or side ventilation is required when rack
mounting (see cooling, PAR. 2.4). Optional slides (see Table 1-5) can be used. See Figure 2-10
for outline dimensions, see Figure 2-11 for outline dimensions of Dual-channel models.
Four front panel mounting holes are provided. When optional slides are not used, additional
support is required.
When at least 1/2U space is available at the bottom, either a bottom support platform (shelf) or
side support brackets can be used. Contact factory for proper bracket depending on rail set-
back.
For zero-clearance stacking, support must be provided at the rear; contact factory for details.
2.5.2 SLIDE MOUNTING
CAUTION!
Use of any chassis slide other than CS 06 is unauthorized and may
damage the unit and void the warranty.
Refer to the instructions supplied with Chassis Slide CS 06 for slide installation. Use of screws
other than those supplied with CS 06 or pre-installed in slide mounting holes will damage the
unit and void the warranty. Contact factory for non-standard mounting options.
WARNING!
Do not lean on fully extended load. Weight added to the fully extended
unit in excess of 35 lbs. can cause the slide to fail and the unit to fall.
When replacing a unit with slide mounting, disconnect load cables before pulling the unit out.
With the unit fully extended and supported, press release buttons on the two intermediate sec-
tions of the slide and remove the unit from the cabinet.
2.6 WIRING INSTRUCTIONS
Interconnections between an a-c power source and the load, and between the load and the unit
under test are as critical as the interface between other types of electronic equipment. Figure 2-
7 illustrates connections for a typical test setup.
Series EL is provided with a three-terminal IEC appliance coupler for connection of the mains
supply source, one terminal of which is dedicated for the protective earthing conductor; no other
