SECTION 2 - INSTALLATION
2.1 UNPACKING AND INSPECTION
This instrument has been thoroughly inspected and tested prior to packing and is ready for
operation. After careful unpacking, inspect for shipping damage before attempting to operate.
Perform the preliminary operational check as outlined in Section 2.5. If any indication of damage
is found, file an immediate claim with the responsible transport service.
2.2 TERMINATIONS AND CONTROLS
a) Front Panel: Refer to Figure 2-1 and Table 3-1.
b) Internal Controls: Refer to Figure 2-2 and Table 2-1.
c) Rear Panel: Refer to Figure 2-3 and Table 2-2.
2.3 SOURCE POWER REQUIREMENTS
WARNING
BEFORE APPLYING THE A-C SOURCE TO THE POWER SUPPLY, VER-
IFY THAT THE LINE VOLTAGE TO BE SUPPLIED MATCHES THE POSI-
TION OF THE AC INPUT SELECTOR SWITCH AT THE REAR PANEL
(FACTORY DEFAULT IS 115V).
This power supply operate with the installed circuit breaker from single phase a-c mains power
over the specified voltage and frequency ranges without adjustment or modification. The AC
INPUT SELECTOR switch located on the rear panel (Figure 2-3) allows selection of either 115V
a-c or 230V a-c source power.
2.4 COOLING
The power devices used within the power supply are maintained within their operating tempera-
ture range by means of internal heat sink assemblies cooled by an internal cooling fan. The fan
operates at low speed for low ambient temperatures and low internal dissipated power, and at
high speed for high ambient temperature and/or high internal dissipated power. ALL INLET AND
EXHAUST OPENINGS AROUND THE POWER SUPPLY CASE MUST BE KEPT CLEAR OF
OBSTRUCTION TO ENSURE PROPER AIR ENTRY AND EXHAUST. Periodic cleaning of the
power supply interior is recommended. If the power supply 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 surrounding the power supply, does not rise above the specified limits (see
Table 1-2).
