A-C POWER INPUT REQUIREMENTS
The BOP is equipped with a SOURCE VOLTAGE SELECTOR permitting the user to choose
between 115 and 230V a-c operation by means of a screwdriver actuated switch; the switch is
accessed by removing the cover (see Section 5, PAR. 5.2). The switch location is illustrated in
FIG. 2-3. When changing the a-c input voltage, the A-C POWER FUSE must be altered as well,
according to the information given in FIG.2-3.

COOLING
The components in the BOP power supply rely on forced air (towards rear panel) cooling for
maintaining their operating temperature.
ALL OPENINGS MUST BE KEPT CLEAR FROM
ALL OBSTRUCTIONS TO ENSURE PROPER AIR CIRCULATION.
Periodic cleansing of the
interior of the power supply is recommended. If the BOP is rack-mounted or installed in confined
spaces, care must be taken that the ambient temperature (the temperature immediately sur-
rounding the power supply) does not rise above 65°C (149°F).

PRELIMINARY CHECKOUT
A simple operating check after unpacking and before permanent installation, is advisable to
ascertain whether the BOP has suffered damage in shipment. Refer to FIG. 2-2 and Table 2-2.
FOR THE LOCATION AND DESIGNATION OF THE OPERATION CONTROLS AND TERMI-
NALS. Proceed as follows:
A)
Connect the BOP to a 115V a-c source, or refer to PAR. 2.3 for conversion to 230V a-c
operation if required.
NOTE: THE REAR PROGRAMMING CONNECTOR MUST BE ATTACHED TO THE BOP
AND MUST BE WIRED AS SHOWN ON FIG 2-4.
