3.5.3 Power Supply and Communication Lines
The primary AC (mains) power service must comply with the local specifications for
grounding the primary power service entrance. The AC power needs to be continuous,
without spikes and blackouts.
The following applies to all
field cabling:
• To protect the cabling from wildlife or vandalism, use armored field cables. The cables
must be suitable for underground use.
• Check the cross-sectional area of the cable core according to maximum allowable
voltage drop.
• Route the cables through protective conduits into the equipment according to the local
requirements.
• Check cable conduit diameters or use additional termination boxes.
• Ground the cable shield at both ends, if possible.
Always make a detailed cabling and wiring plan. If you are going to use an external DC
power system, plan the power supply carefully according to the power needs.
Use a conduit to protect the cables from damage and moisture. Also
trac,
standing water, ice, and any twist or stress will damage the cables.
CAUTION!
3.6 Unpacking
The weather station enclosure, mounting accessories, and the sensors are packed into
cartons. The contents of the cartons may vary depending on the selected options.
1. Check the contents against the packing list.
For customized systems, check also the system documentation.
2. Check the cartons and boxes for possible damage. Check that there are no loose parts
or connectors before installing the mechanics of the equipment and cabling them. If
there has been any damage, contact Vaisala without delay.
3. Remove the parts and the foam packing from the containers carefully. Save the
containers and all the foam packing for future transporting or shipping.
Handle the equipment gently. Do not touch the surface of any
sensors, and do not drop, scratch or bend any part of the equipment.
WARNING!
