Special Conditions for Safe Use (x):
1. Provisions shall be made, external to the apparatus, to prevent the
rated voltage of the apparatus supply is not exceeded by transient
disturbances of more than 40%
2. The electrical circuit is connected directly to earth; this must be taken
into account when installing the apparatus.

Special Conditions for Safe Use (x):
1. The user must ensure that the maximum rated voltage and current
(42.4 volts, 22 mA, DC) are not exceeded. All connections to other
apparatus or associated apparatus shall have control over this
voltage and current equivalent to a category “ib” circuit according to
EN50020.
2. Component approved EEx e cable entries must be used which
maintain the ingress protection of the enclosure to at least IP66.
3. Any unused cable entry holes must be filled with component
approved EEx e blanking plugs.
4. The ambient temperature range of use shall be the most restrictive of
the apparatus, cable gland, or blanking plug.
