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 480M Display and Control Panel

14 Teledyne API Model 480M O3Monitor User Manual 09420A DCN8343
3.1. UNPACKING
Upon receiving the 480M 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 sizes
and locations of the four mounting holes, which are 0.32” (8.128 mm)
diameter.
•All four mounting holes should be used to secure the monitor.
•If using bolts, ensure they are stainless steel, 5/16” (8 mm) diameter, 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 receptacle labeled
“Earth Ground” on the 3-pin AC connector. Failure to do so may result in a
shock hazard and malfunction of the monitor.
3.3.1. WIRING REQUIREMENTS
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

09420A DCN8343 Teledyne API Model 480M O3Monitor User Manual 17
3.3.2. WIRING INSTRUCTIONS
1. Install a ½” conduit fitting for routing the electrical wiring into the monitor
through the hole provided in the bottom face of the NEMA enclosure; an
appropriate sealed conduit connector should be used.
2. Hard-wire the electrical connection to the terminal block and grounding lug
on the chassis. AC power connection to the monitor should be made with 12-
14 AWG stranded 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.
Figure 3-3. AC Power Connection to Monitor

18 Teledyne API Model 480M O3Monitor User Manual 09420A DCN8343
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 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.
