Tighten all cable glands with the appropriate torque.
Ensure that all cable glands are in good condition and are securely
tightened.
Close all unused cable glands with the appropriate sealing plugs.
Requirements for Cables and Connection Lines
Observe the maximum permissible length of cables and connection lines.
The dielectric strength of the insulation must be at least 500 V according to
IEC/EN 60079-14.
Observe the permissible core cross section of the conductor.
The insulation stripping length must be considered.
When installing the conductors the insulation must reach up to the
terminal.
When using stranded conductors, crimp wire end ferrules on the
conductor ends.
Observe the minimum bending radius of the conductors.
The nominal core cross section of a connected conductor is 2.5 mm
2
(solid, finely stranded, and stranded).
Unused cables and connection lines must be either connected to terminals
or securely tied down and isolated.
Install the cables and connection lines in such a way that they are
protected from ultraviolet radiation.
Install cables and cable glands in a way that they are not exposed to
mechanical hazards.
Equipotential bonding must be achieved along the field circuits.
Requirements in Relation to Electrostatics
Avoid electrostatic charges which could result in electrostatic discharges
while installing, operating, or maintaining the device.
Avoid inadmissibly high electrostatic charge of the cables and connection
lines.
Include the metal housing components in the equipotential bonding.
An electrostatic charge poses an ignition hazard in case of discharge.
Include the fasteners in the equipotential bonding.
Requirements for Surrounding Enclosures
If additional surrounding enclosures are required, the following points must
be considered during installation:
l
Degree of protection according to IEC/EN 60529
l
Resistance to light according to IEC/EN 60079-0
l
Resistance to impact according to IEC/EN 60079-0
l
Resistance to chemical agents according to IEC/EN 60079-0
l
Thermal endurance according to IEC/EN 60079-0
l
Electrostatics according to IEC/EN 60079-0
Mount the surrounding enclosure in a way that all housing outlets, e. g.,
cable glands and breather drains face downwards.
When the enclosure cover is fitted, ensure that all fasteners are fully
tightened.
Mount the device so that it complies with the specified degree of
protection according to IEC/EN 60529.
For cable glands only use incoming cable diameters of the appropriate
size.
Ensure that the surrounding enclosure is not damaged, distorted, or
corroded.
Ensure that all seals are clean, undamaged, and correctly fitted.
Tighten all screws of the surrounding enclosure/surrounding enclosure
cover with the appropriate torque.
Close all unused enclosure holes with the appropriate stopping plugs.
8. Operation, Maintenance, Repair
Prior to using the product make yourself familiar with it. Read the
instruction manual carefully.
Do not stay below the open device. In order to avoid personal injuries or
property damage, make appropriate provisions for the mounting and
maintenance procedures.
Observe IEC/EN 60079-17 for maintenance and inspection.
Do not use a damaged or polluted device.
If there is a defect, the device must be repaired by Fuchs.
The device must not be repaired, changed, or manipulated. In case of
failure, always replace the device with an original device.
Observe the warning markings.
Do not remove the warning markings.
If the device is installed in potentially explosive dust atmosphere, remove
dust layers which exceed 5 mm in regular intervals.
Remove the dust before opening the surrounding enclosure.
Connection or disconnection of energized non-intrinsically safe circuits is
only permitted in the absence of a potentially explosive atmosphere.
If cleaning is necessary while the device is located in a hazardous area, in
order to avoid electrostatic charging only use a clean damp cloth.
The device can get very hot during operation. To protect the device from
excessive heating, observe the required clearances and sufficient
ventilation when installing the device.
9. Delivery, Transport, Disposal
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the
ones you ordered.
Keep the original packaging. Always store and transport the device in the
original packaging.
Store the device in a clean and dry environment. The permitted ambient
conditions must be considered, see datasheet.
The device, built-in components, packaging, and any batteries contained
within must be disposed in compliance with the applicable laws and
guidelines of the respective country.
