3. Special conditions for safe use
Caution
3.1
For Group III, the enclosure must be mounted in a location where the risk of
electrostatic discharge is minimised.
3.2
The enclosure of the product is made of aluminium, if it is mounted in an
area where the use of EPL Ga apparatus is required, it must be installed such
that, even in the event of rare incidents, ignition sources due to impact or
friction sparks are excluded.
3.3
The equipment is not capable of passing a 500V dielectric strength test
between the power and signal connections and the housing. This shall be
taken into account during installation.
4. Instruction for safe use
Caution
4.1
To maintain the degree of protection of IP66 in accordance with IEC 60529,
suitable cable glands, conduit sealing devices or blanking elements must be
used and correctly installed.
4.2
The equipment is to be connected with power supplies through a safety
barrier suitable for the terminal parameters of the equipment.
