Connection

Danger!
Explosion hazard from live wiring of non-intrinsically safe circuits
If you connect or disconnect energized non-intrinsically safe circuits in a potentially
explosive atmosphere, sparks can ignite the surrounding atmosphere.
Only connect or disconnect energized non-intrinsically safe circuits in the absence
of a potentially explosive atmosphere.
Danger!
Danger to life from electric shock
Absent or insufficient insulation can result in electric shock.
• Maintain sufficient distance between the connection lines, terminals,
surrounding enclosure, and the environment.
• Insulate connection lines, terminals, and the surrounding enclosure from the environment.
Danger!
Danger to life from incorrect installation
Incorrect installation of cables and connection lines can compromise the function
and the electrical safety of the device.
• Observe the permissible core cross section of the conductor.
• When using stranded conductors, crimp wire end ferrules on the conductor ends.
• Use only one conductor per terminal.
• When installing the conductors the insulation must reach up to the terminal.
• Observe the tightening torque of the terminal screws.

Danger!
Danger to life from electric shock
Working on live parts at voltages higher than 50 V AC or 120 V DC can result
in electric shock.
1. De-energize the device.
2. Secure the circuit against reconnection.
3. Verify that the device is de-energized at all poles.
4. Provide protection from adjacent live parts, if present.
