4.6 Electromagnetic compatibility
If several devices are switched in parallel on the mains side so
that the line current of the arrangement is in the range of 16 - 75
A, then this arrangement conforms to IEC 61000-3-12 provided
that the short-circuit power S
sc
at the connection point of the
customer system to the public power system is greater than or
equal to 120 times the rated output of the arrangement.
It is the responsibility of the installation engineer or operator/
owner of the device to ensure, if necessary after consultation
with the network operator, that this device is only connected to
a connection point with a S
sc
value that is greater than or equal
to 120 times the rated output of the arrangement.
4.7 Ex areas
The device may only be used according to the specifications in the
operating instructions; see chapter 3. Proper use.
Zone classification
The zones describe how long an explosive atmosphere may be present.
Zones 1 and 2 permit only gases, vapours and mist (no dust) which
occur occasionally to seldom in normal operation.
Device categories
The device is approved for Category 2 of Equipment Group II. The
categories define the degree of safety.

Special conditions for safe use
●
The design specifications of the manufacturer must be observed when
repairing flame-proof joints. Repair work based on the values of EN
60079-1 is not permissible.
●
The cable glands used are only to be employed for fixed installation.
Appropriate strain relief must be ensured on installation.
●
When replacing cable entries, make sure that these are suitable for a
sustained usage temperature of -55°C to +80°C.
●
At ambient temperatures below -20°C the connection lines must be
suitable for the corresponding usage temperature.
●
The heating element should only remain switched on at ambient
temperatures up to max. +30°C.
