2. BEFORE GETTING STARTED
2.1 POINTS OF CAUTION
n
CONFORMITY WITH EU DIRECTIVES
• This equipment is suitable for Pollution Degree 2 and Installation Category II (transient voltage 2500V). Reinforced
insulation (alarm output to RUN contact output to power input to FG/Ethernet/RS-485: 300V) is maintained
*
. Prior
to installation, check that the insulation class of this unit satisfies the system requirements.
• The equipment must be mounted on a panel surface. Once mounted on a panel, take appropriate precautions to
prevent operators to be exposed to the terminal block
*
.
In order to enable the operator to turn off the power input immediately, install a switch or a circuit breaker according
to the relevant requirements in IEC 60947-2 and properly indicate it
*
.
• Altitude up to 2000 meters
*
.
• Insert noise filters for the ports explained below.
- For the power source, input, and LAN cable connected to the unit, NEC Tokin ESD-SR-250 or equivalent model is
recommended.
- For the power source and input connected to the unit, COSEL NAC-06-472 or equivalent model is recommended.
- Be sure to connect the unit’s FG terminal to the ground terminal of the filter, which is inserted in the power source,
and connect the ground terminal of the filter to the most stable grounding point with shortest length.
• The actual installation environments such as panel configurations, connected devices, connected wires, may affect
the protection level of this unit when it is integrated in a panel system. The user may have to review the CE require-
ments in regard to the whole system and employ additional protective measures to ensure the CE conformity.

SAFETY PRECAUTION
• This equipment is for use in general industrial environments, therefore may not be suitable for applications which
require higher level of safety (e.g. safety or accident prevention systems) or of reliability (e.g. vehicle control or com-
bustion control systems).
• For safety, installation and maintenance of this equipment must be conducted by qualified personnel.
• Before you remove the module, turn off the power supply and input signal for safety.
• Do not use the 73VR21x in an environment where flammable gases are present. This may result in an explosion.
• Do not disassemble or modify the 73VR21x in any way. Doing so may result in a fire or an electrical shock.
• Do not strike the panel of the 73VR21x with a hard, heavy or pointed object, or press the panel with excessive force.
Doing so may result in panel damage or injury.
• Do not block the 73VR21x’s ventilation openings or use it in areas where heat accumulates. Additionally, do not store
or use it under high-temperature conditions.
• Do not store or use the 73VR21x in locations subject to direct sunlight, or where excessive dust or dirt is present.
• The 73VR21x is a precision instrument. Do not store or use it where large shocks or excessive vibration can occur.
• Do not store or use the 73VR21x in environments subject to chemical evaporation (such as that of organic solvents),
or where there are chemicals and/or acids present in the air.
• Do not use paint thinner or organic solvents to clean the 73VR21x.
• Observe the environmental conditions when using the 73VR21x.
• Wait at least for 5 seconds before turning on the power supply after it has been turned off. The 73VR21x may not
start up if the time interval is less than 5 seconds.
n
ENVIRONMENT
• Indoor use.
• The 73VR21x is designed to be mounted on a vertical panel. It is not suitable for a slanted or a horizontal panel surface.
• Environmental temperature must be within 0 to 50°C (32 to 122°F) with relative humidity within 30 to 85% RH in order
to ensure adequate life span and operation.
• Desktop type cannot be mounted on a panel surface.
• The handle and rubber feet cannot be detached from desktop type unit.
