Warning!
• Risk of electric shock! Switch off the power supply before opening the device. Do not install
or wire the device while it is connected to the power supply. Failure to comply with this
precaution can result in irreparable damage to the electronics.
• Risk of electric shock! Connect the protective conductor to the ground terminal on the
housing before the power supply is applied.
"
Caution!
• Only sensors and transmitters with the same serial number can be connected to one
another. Communication problems can occur if the devices are not connected in this way.
• Risk of damaging the coil driver. Always switch off the power supply before connecting or
disconnecting the coil cable.
Procedure
1. Transmitter: Remove the cover from the connection compartment (a).
2. Sensor: Remove the cover from the connection housing (b).
3. Feed the signal cable (c) and coil current cable (d) through the appropriate cable entries.
"
Caution!
Secure the connecting cable (see "Length of connecting cable" → 19).
4. Terminate the signal and coil current cable in accordance with the table:
Promag E/L/P/W Please see the "Cable termination" table → 52
Promag H Please see the "Cable termination" table → 53
5. Set up the wiring between the sensor and the transmitter.
The wiring diagram applicable to your device can be found:
‣ in the relevant diagram:
→ 30 (Promag E/L/P/W); → 31 (Promag H)
‣ in the cover of the sensor and transmitter.
!
Note!
The cable shields of the Promag H sensor are grounded using strain relief clamps
(please see the "Cable termination" table → 53).
"
Caution!
Insulate the cable shields that are not connected. This eliminates the risk of short-
circuits with neighboring cable shields inside the connection housing.
6. Transmitter: Secure the cover on the connection compartment (a).
7. Sensor: Mount the cover on the connection housing (b).
