Mounting; Connections - H2Scan HY-ALERTA 1600 Operating Manual

Intrinsically Safe Power Barrier: H2scan's custom designed barrier supplies 10VDC, 6W power to
the sensor.
Intrinsically Safe Analog Output Barrier (4mA to 20mA): GM International D1054S or
equivalent, One Channel Repeater Power Supply and Trip Amplifiers. Refer to the D1054S
Operating Manual for installation and configuration of this barrier.
Intrinsically Safe Serial Interface Barrier (RS422): GM International D1061S or equivalent,
RS422 / RS485 Fieldbus Isolating Repeater. Refer to the D1061S Operating Manual for installation
and configuration of this barrier. This barrier also requires a null modem cable for communication

MOUNTING

While the unit can be mounted in any orientation or position, it is important to consider the possible
sources and areas of accumulation of hydrogen gas. Typical installations are near the ceiling level
above equipment using or storing hydrogen. For earlier detection artificial means of accumulation
such as flat plates or inverted trays can be installed at lower heights to allow hydrogen to reach the
sensor more quickly.
WARNING: IT IS NOT THE INTENT OF THIS MANUAL TO SPECIFY MOUNTING LOCATION(S). IT IS THE
REPONSIBILITY OF THE USER AND INSTALLER TO DETERMINE THE PROPER LOCATION(S) FOR
HYDROGEN DETECTION BASED UPON THE PARTICULAR USES OF HYDROGEN AT THE
INSTALLATION SITE.
Mounting is achieved by 4 mounting tabs that can be rotated to align with flat, angled or moderately
curved surfaces. Mounting hardware should be a 4 mm screw (M4, #8 screw), appropriate for the
surface being mounted upon. The unit can be mounted in any orientation or position.
