Device casing
Only technicians authorized by the manufacturer are permitted to open
the casing.
Never insert pointed objects (narrow screwdrivers, wires, etc.) into the
device or into the connection terminals for electric conductors. Do not
touch the connection terminals.
Keep the ventilation slits free to ensure good air circulation.
See “General technical data” on page 45.
Mount the device in the vertical position.
At ambient air temperatures > 140 °F (+60 °C):
The surfaces of the device housing may become hot. Avoid touching
the device while it is operating.
Requirements for connecting electrical wires
Before connecting the electrical wires, always verify that the
requirements listed are complied with.
Requirements for connecting the signal contact
Before connecting the signal contact, always verify that the requirements
listed are complied with.
Requirements for connecting the supply voltage
Before connecting the supply voltage, always verify that the requirements
listed are complied with.
The following requirements apply without restrictions:
The electrical wires are voltage-free.
The cables used are permitted for the temperature range of the application case.
Relevant for North America:
Exclusively use 60/75 °C (140/167 °F) or 75 °C (167 °F) copper (Cu) wire.
Table 1: Requirements for connecting electrical wires
The following requirements apply without restrictions:
The voltage connected complies with the requirements for a safety extra-low voltage
(SELV) as per IEC/EN 60950-1.
The connected voltage is limited by a current limitation device or a fuse.
Observe the electrical threshold values for the signal contact.
See “General technical data” on page 45.
