4.4 Laying Cables in the DC Subdistribution
1. Disconnect the DC sub-distribution (see the DC sub-distribution manual). Always observe the
five safety rules.
2. Remove the protective covers of the DC subdistribution (see the DC subdistribution manual).
3. Insert one or two optical fibers or SC/SC duplex patch cables into the DC subdistribution as
needed, (see Section 4.2 "Overview of the Connection Area of the SMA String-Monitor",
page 21) and carefully lay the cables in accordance with the cable route (see Section 4.3
"Mounting Position and Cable Route", page 22). Observe the minimum bending radii.
4.5 Installing the Optical Fiber Interface Module
The optical fiber interface module can also be operated without a splice box. Pre-assembled optical
fibers with a subscriber connector must be used for this during installation.
Requirements:
☐ The DC subdistribution and the inverter must be disconnected. Always observe the five safety
rules.
☐ The optical fibers must be laid in the DC subdistribution.
Damage to electronic components due to electrostatic discharge
Electrostatic discharge can damage or destroy electronic components.
• Observe the ESD safety regulations when working on the product.
• Wear suitable personal protective equipment for all work on the product.
• Discharge electrostatic charge by touching grounded enclosure parts or other grounded
elements. Only then is it safe to touch electronic components.
Procedure:
• Plug the optical fiber interface module onto the required slot on the DC subdistribution (see
Section 4.3 "Mounting Position and Cable Route", page 22):
