LEANING
Because the module uses forced convection cooling, the air flow through the
unit can pull in dust. In environments having high concentrations of dust,
periodic cleaning may be required. The exterior of the unit should be cleaned
with a mild solution of detergent and water. The solution should be applied onto
a soft cloth, and not directly to the surface of the unit. To prevent damage to
materials, do not use aromatic hydrocarbons or chlorinated solvents for
cleaning.

NSTALLATION
CAUTION
The module contains ESD sensitive circuitry. Follow appropriate
handling and grounding procedures to prevent damage to the module.
The module should be handled by the enclosure, with care to protect the
connectors from ESD discharges.
CAUTION
Input power must be disconnected to the Mainframe before a module is
inserted or extracted. Inserting or extracting a module with power installed
(hot-swapping) could result in damage to the module or Mainframe. Prior to
turning power on, ensure that front panel captive fasteners are tightened
The DC power supply modules are installed into the Mainframe from the
front of the chassis. Refer to Figure 6-4 for a view showing the orientation
of a module and Mainframe during installation.
1. Ensure that the AC/DC input power is disconnected before installing
or removing any module(s).
2. Insert the module into the Mainframe, aligning the guide rails at the
rear of the module with the top and bottom Mainframe guides.
3. Gently slide the module completely into the Mainframe until the guide
pins of the module rear connector engage the mating backplane
connector.
4. Fully seat the module until the front panel inner surface is snug
against the Mainframe chassis.
5. Secure the module(s) to the Mainframe at the top and bottom of each
front panel by turning the captive thumbscrews clockwise to a
maximum torque of 20 in-lb, using a flat blade torque screwdriver.
6. Install a filler panel over any empty slot, and secure in place at the top
and bottom by turning the captive thumbscrews clockwise to a
maximum torque of 20 in-lb, using a flat blade torque screwdriver.
