CONFORMITY WITH EC DIRECTIVES
• This equipment is suitable for use in a Pollution Degree 2 environment and in Installation
Category II. 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 re
-
quirements.
• 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 60947-1 and IEC 60947-
3 and properly indicate it*.
• Altitude up to 2000 meters*
• Insert a noise filter for the power source and RS-485 line connected to the unit. NEC
Tokin Noise Filter Model ESD-SR-250 or equivalent is recommended.
• 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 requirements in regard to the whole
system and employ additional protective measures to ensure the CE conformity.
*Except desktop type

POWER INPUT
• Power input rating & operational range: Check the power rating for the unit on the speci
-
fication label.
Rating 100 – 240V AC: 85 – 264V, 47 – 66 Hz,
approx. 15VA at 100V, approx. 20VA at 240V
Rating 24V DC:
24V ±10%, approx. 8W, 340mA
• Supplying any level of power other than specified above can damage the 73VR1100 or
the power source.
• The power cables and the signal I/O cables for the 73VR1100 must be located sepa
-
rately.
• The main circuit cables (high voltage and high current), the signal I/O cables, and the
power cables should not be bundled together or placed near each other.
•
To increase noise resistance of the power input wires, twist the strands before connecting.
