Chapter 3
Physical Configuration
3.1 Instrument
3.1.1 Location Considerations
The Model 1073A is designed to operate in an environment having an ambient temperature range
of 0 ◦C to +50 ◦C (+32 ◦F to +122 ◦F). Operation is possible at temperatures of −20 ◦C to +70 ◦C,
typical. No external ventilation is necessary.
For best access to the 1073A, allow adequate clearance for rear-panel connections, especially in
rack-mounting situations.
3.1.2 Power Requirements
The standard AC input voltage range for the Model 1073A is 85 Vac to 264 Vac, 47 Hz to 440 Hz,
110 to 275 Vdc, or 10 to 60 Vdc. See Section 3.1.3.
3.1.3 Power Line Connection
The Model 1073A is equipped with a user specified Power Input Module. The modules available
are described in the following paragraphs.
Option 07, AC/DC Power Input Module (IEC-320 Inlet)
AC Operation
This power inlet module operates across an AC input voltage range of 85 – 264 Vac, 47 – 440 Hz.
The mating cordset provided is dependent upon the cordset option (P1 through P10) which was
specified at the time of purchase. For further information about available cord sets for specific
countries, see Table 1.1, or contact Arbiter Systems.
To connect the input power, first plug the end of the power cord having the mating IEC
connector into the power inlet module on the rear panel, then plug the other end into an appropriate
power outlet.
WARNING: For maximum safety and best performance, always connect the
input cord to a properly grounded power source.

8 Physical Configuration
DC Operation
For 110 – 270 Vdc operation, the DC voltage should be applied between the LINE and NEUTRAL
terminals of the power inlet module, without regard to polarity (the internal power supply will
accept either polarity). When viewing the power inlet module from the rear of the instrument,
the LINE connection is the one nearest the bottom, and the NEUTRAL is nearest the top. The
GROUND terminal is offset from the others, and protrudes slightly farther out of the connector.
WARNING: Connect input only to a properly grounded power source.
Option 08, DC Power Input Module
If Option 08 is ordered, the power module accepts ONLY DC input voltages from 10 – 60 Volts. The
standard IEC-320 inlet is replaced with a 3-pole terminal strip with input surge withstand capability
(SWC). The terminal strip is intended for connection to DC power sources. When connecting power
to a clock with Option 08, BE SURE TO OBSERVE CORRECT POLARITY, as the power
supply used with Option 08 will not accept reverse input polarity.
NOTE: Do not connect Option 08 module to any AC voltage source.
Option 10, AC/DC Power Input Module
AC Operation
This option provides a input power module which operates across an AC input voltage range of
85 – 264 Vac, 47 – 440 Hz. Line connection is via a 3-pole terminal strip which provides surge
withstand capability (SWC). This terminal strip is intended for connection to AC power sources,
although the unit is capable of operation from both AC and DC sources.
DC Operation
The input power module supplied with this option also accepts DC voltages from 110 – 270 Vdc
via the 3-pole terminal strip (with SWC).
Fuse Replacement, All Power Supply Options
The IEC-320 input power connector assembly includes a 1-Amp, 250-Volt fast-acting 5 x 20 mm
fuse. The fuse is contained in a small compartment with a snap-fit latch, which also has a com-
partment for a spare fuse.
CAUTION: For continued protection, replace the input fuse only with
one of the same type, voltage rating, and current rating as originally
supplied.
The fuse compartment in Option 07 is located directly adjacent to the input connector socket,
and can be opened by pulling both sides directly upward, or by gently prying with a small flat-
blade screwdriver. To replace the fuse, first disconnect the line cord from the power source and
