WARNING:
Unallowed voltage supply voids the Ex certification
Only connect the TRANSIC151LP via the TSA151 voltage supply unit.
Only use a 24V DC PELV power supply unit on the TSA151 voltage supply unit.
▸
Observe the “X” marking on the type plate,
see “Product identification”, page 11
WARNING:
Using unallowed cables voids the Ex certification
If the cables are not SICK standard cables, they must meet the cable specifications in
Table
