Warning
Failure to follow safety precautions in this chapter could result in serious injury or death.
3.1 Requirements for installation
3.1.1 Electrical requirements
Mains power
Make sure the mains power supply for the system is easily accessible and not too far away from the barn
in which the units are placed. The power sockets shall be installed near the equipment and must be easily
accessible.
Caution
Nedap power supplies must be connected to a power socket with protective earth (PE). Always use a 3-pole
connector with a PE contact.
If there is no PE available, create a PE next to the power socket to be used for each power supply. The
properties of a correct PE depend on local circumstances and legislation. Always comply with local rules and
regulations when installing earth electrodes.
Network
Use a fiberglass network between the VPUs (VP8002) if
• the power supplies have different power sources with a separate PE;
• the distance between two VPUs or the distance between one VPU and a router/switch exceeds 100 m (330
ft.);
• there is often lightning in the area.
Cabling
Install Velos CAN cable(s) and Ethernet cable(s) inside a plastic (PVC) conduit.
• Do NOT install cables directly to metal ceiling, trusses and feed lines.
• Install fiberglass cables inside a plastic (PVC) conduit with an inner diameter of at least Ø 25 mm (1 in.).
Surge protection and UPS
Caution
Always use surge protectors with Ethernet surge protection.
Install an Uninterruptible Power Supply (UPS) that is connected to the VP2001 when the power source is not
reliable and constant. The UPS is intended to correctly power down the VP8002 and will also run the other V-
packs in the Nedap system for a brief period.
The VP8002 has internal backup power that will shut down the VP8002 correctly when the power is
interrupted. The internal backup power will not run the other V-packs in the Nedap system.
