DANGER
Danger when connecting the device.
If you do not comply with the safety notes, this will result in death, severe injury, or considerable material
damage.
²
The device must be situated in the operating area for at least 2 hours before you connect it to the
power supply for the first time. This avoids condensation to occur in the device.
²
Perform the electrical inspection (refer to
1.4.5 Performing the Electrical Inspection

Grounding a Device
The device has to be connected to the protective earthing conductor of the cabinet prior to commissioning.
!
CAUTION
The cross-section of the ground wire must be equal to or greater than the cross-section of any other
control conductor connected to the device. The cross-section of the ground wire must be at least 2.5 mm
2
(AWG14).
The following consequences can occur if the cross-section of the ground wire is not properly installed:
- The device can be damaged.
- Touching the device can cause a flashover and health damage if the device is not sufficiently grounded.
- A faulty activation can occur by undefined states.
²
The cross section of the ground wire and the laying of the wire must comply with the regulations
applicable for the place of installation.
Ground the device with solid low-resistance system grounding (cross-section ≥ 4.0 mm
2
, grounding
area ≥ M4).
Connecting the Device
²
Connect all cables and lines. Use the connection diagrams stated in the Equipment Manual.
²
Tighten the terminal screws.
