SMA SSM-U-1615 - Manual (Page 40)

☐ Maximum cable length: 30 m
☐ External cable diameter: 3.2 mm to 6.5 mm
Additionally required material (not included in the scope of delivery):
☐ 1 irradiation sensor or 1 anemometer
☐ 1 connection cable
Requirement:
☐ The sensor must be technically suitable for connection to the analog input of the DC
subdistribution (see Section 13, page 65).
Procedure:
1. Connect the cable to the sensor (see manufacturer manual). Trim the unneeded insulated
conductors up to the cable shield and note down the conductor colors.
2. Lead the other end of the cable through the corresponding enclosure opening (see
Section 6.1, page 25) into the DC subdistribution (see Section 12.1, page 62).
3. Prepare the cable for connection as follows:
• Remove 40 mm of cable sheath at the end of the cable.
• Strip the conductors by 6 mm.
4. Lead the cable through the cable channel as far as terminal X1 (see Section 4.4, page 17) of
the electronic assembly and out of one of the lateral slits in the cable channel. To do this, you
can remove and reattach the cover of the cable channel.
5. Connect the cable to terminal X1 (see Section 4.4, page 17) of the electronic assembly
according to the circuit diagram. Observe the pin assignment.
6. Attach the cable to the cable support rail in the DC subdistribution.
6.6 Connecting the Remote Terminal to the Digital Input
You can connect e.g. a remote signaling contact to the digital input of the DC subdistribution.
Cable requirements:
☐ Number of insulated conductors: at least two
☐ Conductor cross-section: 0.08 mm
2 to 1 mm 2
☐ Maximum cable length: 30 m
☐ External cable diameter: 3.2 mm to 6.5 mm
Additionally required material (not included in the scope of delivery):
☐ 1 remote terminal
☐ 1 connection cable
Requirement:
☐ The remote terminal must be technically suitable for connection to the digital input of the DC
subdistribution (see Section 13, page 65).
