3. GETTING STARTED
WARNING –RISK OF DEATH OR SERIOUS INJURY!
To reduce the risk of death or serious injury from a
chemical/combustion explosion hazard due to flammable
gases/vapors/liquids, never allow contaminants to enter monitor
during installation or use. The combination of ozone and the catalytic
ozone destruct media in the monitor can produce strong oxidation
reactions. Never allow organic contaminants, including but not limited
to peroxides and chlorates, into monitor.
Figure 3-1. Model 480L Display and Control Panel
The monitor is shipped with this user manual and for rack mount version, a power
cord.

09419A DCN8342 Teledyne API Model 480L O3Monitor User Manual 13
3.1 UNPACKING
Upon receiving the monitor please verify that there is no apparent shipping damage.
(If damage has occurred, please advise shipper first, then Teledyne API).
Check your packing slip for options that may be included, depending on your order,
e.g., disposable sample inlet filters.
3.2 MECHANICAL INSTALLATION
When installing the monitor, be sure to leave sufficient clearance on sides, top, and
bottom for adequate ventilation and for access to make/adjust all connections. The
monitor must be mounted securely with four (4) bolts or anchors to a vertical
structure or wall capable of supporting 80 lbs. The mounting bolts or anchors must
be capable of supporting 20 lbs each. If using wall anchors, they must be suitable
for the type of wall construction and installed per the manufacturer’s specifications.
•The illustrations in Figure 3-2 show the mounting dimensions and the
locations of the four mounting holes, which are 0.32” (8.128 mm) diameter.
•All four mounting holes must be used to secure the monitor.
•If using bolts, ensure they are stainless steel, 5/16” (8 mm), capable of
supporting 20 lbs each.

3.3 AC POWER CONNECTION
WARNING – Electrical Shock Hazard
Disconnect power to the AC mains before making or removing any electrical
connections to the monitor.
A proper earth ground connection must be made to the copper lug with the
ground symbol on the chassis. Failure to do so may result in a shock hazard
and malfunction of the monitor.
3.3.1 WIRING REQUIREMENTS FOR NEMA ENCLOSURES
Use appropriate wiring rated for this type of equipment, ensuring that it meets local
and national safety and building requirements.
Ensure that overcurrent protection is used on AC mains connections (a 5 A circuit
breaker is recommended), and that it fulfills the following requirements:
•be located as near to the instrument as possible
•quickly and easily accessible
•clearly labeled as the disconnecting device for this instrument
3.3.2 WIRING INSTRUCTIONS
For the NEMA configuration, the electrical connection must be hard-wired to the
terminal block and grounding lug on the chassis. AC power connection to the
monitor should be made with 12-14 AWG copper wire, connected to the monitor as
follows:
•Earth Ground (green):Connect the earth ground wire to the copper grounding lug
•Line (Black):Connect the Line wire to the terminal block directly across
from the black wire that leads to the power supply
•Neutral (White):Connect the Neutral wire to the terminal block directly
across from the white wire that leads to the power supply.

16 Teledyne API Model 480L O3Monitor User Manual 09419A DCN8342
Figure 3-3. NEMA AC Power Connection to Monitor
1. Connect the power cord to an appropriate power outlet or hardwired connection (see
the serial number tag for correct voltage and frequency).
WARNING
Verify that the instrument specification for proper line
voltage and frequency is followed. Observe local electrical
codes when connecting power to the monitor.
2. Turn on the 480L by applying power to the monitor. The front panel display will light
and display a Teledyne splash screen. The home screen will display the ozone
concentration and flow after the monitor begins taking stable readings.

3.4 ELECTRICAL I/O CONNECTIONS
In the NEMA configuration, the I/O connectors are located internally in the
instrument. See Figure 3-4 for their locations. Connection to these terminals is
usually made via a conduit connection to the NEMA enclosure. There are two
conduit penetrations on the enclosure, and an additional penetration can be added to
one of the walls of the enclosure if needed.
Figure 3-4. Interior Location of I/O Connectors

3.4.1 ANALOG OUTPUT
Refer to Figure 3-4 for the location of the analog output, which can be configured
for 0-5 V voltage or 4-20 mA current output. See Section 3.4.1.1 for details on
verifying or changing the analog output hardware configuration.
The analog output is automatically scaled to the range of the instrument. See
Section 5.2.4.1 for information on changing the range of the monitor.
The monitor has an analog output step-test mode that can be used for verifying the
operation of the analog output and calibration of external measurement equipment.
This mode is described in Section 5.2.3.1.
3.4.1.1 ANALOG OUTPUT HARDWARE VERIFICATION OR CONVERSION
To change or verify the configuration of the analog output, refer to Figure 3-5 while
performing the following instructions:
1. Disconnect power from the monitor.
2. Open front panel.
3. Locate J15 and J17 connectors on the Mainboard PCA (remove Relay
Expansion board if installed as indicated in Figure 3-5).
4. Set the desired output as shown in Figure 3-5 where:
•for Current output (4-20 mA), jumper Pins 1-2 on both J15 and J17, or
•for Voltage output (0-5 VDC), jumper Pins 2-3 on both J15 and J17.
5. If applicable, reinstall/connect Relay Expansion board.
6. Re-secure the front panel.
7. Reconnect power to the monitor.
