  • Page 5: General Information

    There are two device variations described in this connecting and operating instructions. The difference between the two devices is in their supply voltage. The TNT 35 is intended for 24V DC operation. The TNT 35/7-24V is intended for 24V AC operation. The basic remarks concerning the functioning and assembly of the safety system are valid for both device variations.
