2.1. Hardware Installation
2.1.1. Installation requirements
Read this section carefully and keep the all requirements. The
Sensformer Connectivity Device uses high voltage, failure to
comply can result in an accident.
As the all of electric devices, the Sensformer Connectivity Device
has a few installation requirements. The device may only be
installed in accordance with these instructions.
Only trained and qualified personnel are allowed to install or
replace or maintenance this equipment.
Do not mount the device under voltage. Risk of electric shock!
Installed the device in a cabinet which satisfies the following:
- at least IP20 protection,
- can be opened with a tool, and can be closed with it.
Above and below the installed device must be get at least 50 mm
free space because of the suitable ventilation. The device does
not require other ventilation. High voltage and warming devices
cannot be placed closer than 50 mm for the Sensformer
Connectivity Device. The device should be only used at operating
temperature.
Minimum temperature rating of the cables to be connected to the
field wiring terminals is 80 °C. Use copper conductors only!
The MAINS field-wiring leads shall not be more than two standard
wire sizes smaller than the copper conductor to which they will
be connected. Also the field wiring leads should not be smaller
than 18 AWG (0,82mm
2
)
The Sensformer Connectivity Device requires the PE (protected
earth). Not allow to use the Sensformer Connectivity Device
without PE. The using PE cable must be green-yellow.
The cables used on the digital inputs and power supply must be
certified, double insulated and must have UL 94 V-1 flammability
classification and VW-1 flame rating.
The cables used on the analog inputs, pt100 input and RS485
communication port must be certified, double insulated and must
be UL 94 V-1 flammability classification and VW-1 flame rating.
In case of digital inputs and power supply, the used cables must
have ferrules. Do not use cables without ferrules about digital
inputs and power supply. The used ferrules must be certified, 1.5
mm
2
conductor area with 16-18 mm overall length and 8 mm pin
length.
For the other ports, the used cables must have ferrules. The
ferrules must be certified, 1.5 mm
2
conductor area with 14 mm
overall length and 8 mm pin length. Do not used cables without
ferrules about the analog inputs, pt100 input and RS485
communication port.
For disconnecting the device from the power supply source there
must be a power circuit breaker installed, which can break the L
(line) and the N (neutral), but it cannot break the PE (protected
earth). The circuit breaker device what it was chosen, it must be
certified. It must satisfy the IEC 60947-1 and IEC 60947-3
standards. The circuit breaker device must be 240 VAC with 1A.
The circuit breaker device must be clearly marked during
installation and the off-position and on-position of circuit breaker
shall be clearly marked. Inscriptions and/or markings shall ensure
that the pairing of the circuit breaker and the connected
(secured) equipment is clearly identifiable.
The circuit breaker device must be close to the Sensformer
Connectivity Device. The recommended distance is lower than 1
meter.
Overcurrent protection must be provided which can break the L
(line) and the N (neutral), but it cannot break the PE (protected
earth). It must be certified. The overcurrent protection must be
240 VAC with 1A.
If the environment requires, the overcurrent protection and the
circuit breaker device can be one device. In this case, the safety
device must can break the L (line) and the N (neutral), but it
cannot break the PE (protected earth).
Connect only certified external devices to outputs that are safety
extra low voltage (SELV) rated to the equipment to avoid the risk
of electric shock.
2.1.1.1. Cleaning
The Sensformer Connectivity Device does not require cleaning or
decontamination.
2.1.1.2. Service
The safety level of the device is not reduced during service, repair
or maintenance.
2.1.1.3. The name and address of the guarantee
service station
