3 Installation
3.1 Instrument
All output connections (including the RS-232 port) use Phoenix type pluggable terminal connectors with 5 mm
spacing. The connector accepts between 0.25 mm and 2.5 mm diameter wire. To connect wires to any of the
terminals, strip the insulation back to expose about 6.35 mm (0.25 in) of bare wire (DO NOT tin the bare end with
solder), insert the stripped wire into the terminal and turn the screw down (clockwise) to secure it in the
connector.
3.1.1 Location
The Model 120A GNSS Synchronized Clock was designed for enclosed applications and will operate over a - 40˚ C
to 85˚ C temperature range. The small size allows for the unit to fit in small spaces. The case is not waterproof so
it must be kept in a weather protected location.
3.1.1 Instrument Mounting
The Model 120A comes with two removable flanges with slots that can be used to secure the unit to a panel or
shelf.
3.1.2 Power Requirements
The Model 120A accepts a dc input voltage b8 and +32 Vdc. The maximum power required for operation
is 5 Watts. The power is connected using a two terminal Phoenix type pluggable terminal connector with 5 mm
spacing. The negative terminal of the power inlet is connected to chassis ground so the power source must be
positive grounded. The power inlet is protected by an internal auto-recovering thermal fuse.
