Example: Single wire resistance = 5 Ω
Resistance of receiver = 50 Ω
Total loop resistance = 55 Ω
Minimum supply voltage = 55 Ω (1 VDC/50 Ω) + 25.1 VDC = 26.2 VDC
SPECIAL CONDITIONS OF SAFE USE:
The apparatus must be mounted within a separate enclosure capable of withstanding a 7
joule impact and providing a minimum ingress protecon of IP54.
The transmier is not capable of withstanding the insulator test required by Clause 6.4.12 of
EN50020:2002. This must be taken into account when installing the driver.
The driver cannot be repaired in the eld and must be replaced by an equivalent unit. The
driver is not to be exposed to dust condions.
The driver should not be installed where it may be subjected to mechanical and excessive ther-
mal stresses or where it may be aacked by exisng or foreseeable aggressive substances.
The apparatus enclosure is made from plasc which must be protected from impact and fricon.
Installer must perform a risk assessment in accordance with Clause 10 of EN60079-25 and
install lightning protecon arresters as deemed necessary.
WARNING – SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY.
AVERTISSEMENT: LA SUBSTITUTION DE COMPOSANTS PEUT COMPROMETTRE LA SECURITE
