High-voltage barrier
High-voltage wiring for the controller is located behind the high-voltage
barrier in the controller enclosure. The barrier must remain in place except
when installing modules or when a qualified installation technician is wiring
for power, alarms, outputs or relays. Do not remove the barrier while power
is applied to the controller.
Electrostatic discharge (ESD) considerations
NOTICE
Potential Instrument Damage. Delicate internal electronic components
can be damaged by static electricity, resulting in degraded performance
or eventual failure.
Note: To minimize hazards and ESD risks, maintenance procedures not requiring
power to the analyzer should be performed with the power removed from the
instrument.
The manufacturer recommends taking the following steps to prevent ESD
damage to the instrument:
• Before touching any instrument electronic components (such as printed
circuit cards and the components on them) discharge static electricity
from your body. This can be accomplished by touching an earthgrounded metal surface such as the chassis of an instrument, or a metal
conduit or pipe.
• To reduce static build-up, avoid excessive movement. Transport staticsensitive components in anti-static containers or packaging.
• To discharge static electricity from your body and keep it discharged,
wear a wrist strap connected by a wire to earth ground.
• Handle all static-sensitive components in a static-safe area. If possible,
use anti-static floor pads and work bench pads.

Wiring for power
WARNING
Potential Electrocution Hazard. Always disconnect power to the
instrument when making electrical connections.
WARNING
Potential Electrocution Hazard. If this equipment is used outdoors or in
potentially wet locations, a Ground Fault Interrupt device must be used
for connecting the equipment to its mains power source.
DANGER
Electrocution Hazard. Do not connect AC power to a 24 VDC powered
model.
WARNING
Potential Electrocution Hazard. A protective earth (PE) ground
connection is required for both 100-240 VAC and 24 VDC wiring
applications. Failure to connect a good PE ground connection can result
in shock hazards and poor performance due to electromagnetic
interferences. ALWAYS connect a good PE ground to the controller
terminal.
• The voltage barrier must be removed before making any electrical
connections. After making all connections, replace the voltage barrier
before closing the controller cover.
• A sealing type strain relief and a power cord less than 3 meters (10 feet)
in length with three 18-gauge conductors (including a safety ground
wire) can be used to maintain the NEMA 4X/IP66 environmental rating.
• Controllers can be ordered with AC power cords pre-installed.
Additional power cords may also be ordered.
• The DC power source that supplies power to the 24 VDC powered
controller must maintain voltage regulation within the specified 24
VDC-15% +20% voltage limits. The DC power source must also provide
adequate protection against surges and line transients.
Wiring procedure
Follow the numbered steps on page 14 and Table 1 or Table 2 to wire
the controller for power. Insert each wire into the appropriate terminal until
the insulation is seated against the connector with no bare wire exposed.

The service port is used to download data files from the controller. To
download data and update software, use the service port in combination
with DataCom and a service cable (LZX887). The service port can also be
used to update controller and sensor firmware.
Using DataCom
When using the service port, it is necessary to use DataCom. DataCom is
a PC Application Utility that downloads data log and event log files from
the controller and installed sensors. Files are downloaded from the
controller through the controller service port or they can be placed on a
Secure Digital Memory (SD) card installed in the controller. In addition,
DataCom is used to upload software for the controller and sensors. The
DataCom application must be installed on a PC to read the files.
Refer to the DataCom manual for more information on how to use the
application. The DataCom manual, software updates and other
downloadable resources are available at http://www.hach.com/download/
resources.
