COOLING
The power transistors and rectifiers in the MAT Power Module are maintained within their oper-
ating temperature range by means of special heat sink assemblies, cooled by an internal fan.
SIDE PANEL OPENINGS AND THE TOP OF THE CASE MUST BE KEPT CLEAR FROM
OBSTRUCTIONS TO ENSURE PROPER AIR CIRCULATION.
If the MAT Power Module is
rack mounted, or installed in confined spaces, care must be taken that the ambient temperature
(the temperature immediately surrounding the Power Module) does not rise above the limit
specified.
2.5
INSTALLATION
The MAT Power Module is designed to be rack-mounted in a standard 19 inch equipment rack
(refer to Figure 1-2, Mechanical Outline Drawing).
For installation into confined spaces, care must be taken that the surrounding environment does
not exceed the maximum specified ambient temperature of 50 °C

GROUNDING
2.6.1
SAFETY GROUNDING
National and international safety standards set procedures for the grounding of a metal cover
and chassis of an instrument connected to an ac power source.
The MAT Power Module is supplied with an ac female plug (MS3106A16-10S, Kepco P/N 143-
0331), that mates with a chassis mounted male receptacle (MS3102A16-10P. Kepco P/N 142-
0268). The pin designations are as follows: A is Hot, B is Safety Ground, and C is Neutral (see
Table 2-3 and Figure 2-2).
