6 Electrical installation
DANGER
• If the transmitter is used in a manner not specified by the
Company, the protection provided by the equipment may
be impaired.
• Refer to page
7 for electrical installation
considerations in Hazardous areas.
• The transmitter conforms to Installation Category II of IEC
61010.
• All equipment connected to the transmitter’s terminals
must comply with local safety standards (IEC 60950,
EN61010-1).
DANGER – CONNECTION/CABLE
REQUIREMENTS
• The connection terminals accept cables with peripheral
wire cross-section of:
– min.: 0.14 mm
2
(26 AWG)
– max.: 1.5 mm
2
(14 AWG)
• Do not use a rigid conductor material as this can result in
wire breaks.
• Ensure the connecting cable is flexible.
• To ensure the sensor cable length is sufficient, allow an
additional 100 mm (4 in) of cable to pass through cable
glands into the housing.
• Ensure the correct connections are made to suit the
transmitter variant.
