10 Safety Advice
This chapter is a summary of the key safety measures. The
summary is supplementary to existing rules which staff also have to
study.
The safety of persons and equipment in hazardous areas depends
on compliance with all relevant safety regulations. Thus, the
installation and maintenance staff carry a particular responsibility,
requiring precise knowledge of the applicable regulations and
conditions.
The notes listed below in section 10.1 must be heeded to avoid injury
and damage to equipment !

When using the camera the operator will have to take into account the fact that the plastic
cover/window has been tested only against small energy mechanical shock.
The EC-750 Ex DOME Camera may only be installed and operated in an undamaged, dry and
clean condition !
10.1.1 Zone 21, 22
When assembling the lid of the camera housing, the O-ring seals must be greased (e.g.
with silicone grease). All cable glands must have at least IP68.
User shall perform a regular cleaning of material, with soft and wet cloth in order to limit
dust layers on the material sides. In this case the user had to observe that only water and
no Alcohol or dissolver will be used for that !
10.2 Special conditions
Each EC-750 Ex DOME Camera version must be associated with the adequate
connector.
The plastic cover/window of the EC-750 Ex DOME Camera should be cleaned only with a
damp cloth (use only water, no Alcohol or dissolver).
The operating ambient temperature is for camera version with cable gland
at T6 and T85°C, -20 °C ≤ Ta ≤ +55 °C
at T5 and T100°C, -20 °C ≤ Ta ≤ +60 °C
11 Installation
11.1 General information
Electrical plants are subject to certain regulations concerning
installation and operation (e.g. RL 1999/92/EC, RL 2014/34/EU and
IEC/EN 60079-14).
It is the responsibility of the operators of electrical installations in
hazardous environments to ensure that the equipment is kept in
proper condition, is operated according to instructions and that
maintenance and repairs are carried out.
11.2 EC-750 Ex DOME Camera
The explosion proof housing of the EC-750 Ex DOME Camera should be installed in
compliance with the recommendations of the following standard EN 60079-14,
EN 60079-17 and EN 50281-1-2.
The free extremity of the short umbilical cable must be connected to the main umbilical
cable either within an enclosure that is certified for the given application, otherwise, this
junction box must be placed away from the dangerous zone.
The earth/ground (PA) connector at the top of the EC-750 Ex DOME Camera housing
must be connected to the equipotential bonding conductor of the hazardous area. The
earth connector must have a minimum cross section of 4 mm².

Because the transmission of the devices remains reliable and stable over long periods of time,
regular adjustments are not required. Repairs may only be done by the manufacturer
exclusively.
System maintenance should focus on the following:
a. Seal wear
b. Plastic cover/window damage
c. All screws are tightened fast
d. All cables and lines are properly connected and undamaged
15.1.1 Servicing
In accordance with IEC 60079-19 and EN 60079-17, operators of electric plants in hazardous
areas are obliged to have them serviced by qualified electricians.
16 Troubleshooting
Devices operated in hazardous areas must not be modified. Repairs
may only be carried out by qualified, authorized staff specially trained
for this purpose.
Repairs may only be carried out by specially trained staff who are
familiar with all basic conditions of the applicable user regulations
and –if requested –have been authorized by the manufacturer.
17 Disposal
Disposal of packaging and used parts is subject to regulations valid in whichever country the
device has been installed.
The disposal of devices sold after August 13th, 2005, and installed in countries under the
jurisdiction of the EU is governed by directive (amendment) 2012/19/EU on waste electrical and
