Packing, storage and transportation

5.1 General

MNS switchgear is shipped either in singIe section or in shipping units not exceeding 3 m in length depending on the type
of equipment instalIed and on the space available for handIing the switchgear at the erection site.

Maximum size of a shipping unit (length × width × height) in mm:
• Unpacked 3100 x 1300 x 2300
• Packed in crate 3300 x 1500 x 2590 (see also “3.1.1 Container shipment”)
The MNS-Up sections must be shipped as individual sections, due to their dimensions and weight.

In all cases the ACB must be transported separately from the section. It is not allowed to transport it within the section.
The ACB requires special attention during transport and handling. Please refer to original manuals 1SDH000999R0002 and
1SDH001000R0002, Chapter 2: Transport and checking on receipt.

Note: Shipping dimensions and weights here are approximate. These are meant to be used a guide only. Please refer to
project specific documentation.

!

Remove all ACBs from sections and transport them separately!

General overview of standard module solutions (customer specific solutions not mentioned)

If no special instructions are given by the customer, packing is carried out based on ABB shipping guidelines and a suitable
method of shipping is selected. Approximate weights for calculation are listed in below tables.

All weights for incoming feeders configured as below:
•  Section weights are defined based on IP30-IP40 internal protection with bottom plate
•  Section weight for EQ400 / EQ600 contains 200 mm main busbar area
•  Section weight for EQ800 contains 400 mm main busbar area
•  Section weights are defined with all possible CTs (measuring and protection), REF relay and SPD
•  Section weights do not contain internal devices (except CTs, REF, SPD) and wiring
•  Section weights do not contain side walls and main busbar end covers

All weights for couplers configured as below:
•  Coupler weights do not contain internal devices (except CTs and REF) and wiring
•  Coupler weights do not contain side walls and main busbar end cover
•  The type of coupler with CTs utilizes different angle set (with more copper) to create place for CTs. If you use coupler

without CTs, the overall weight might be significantly lower.
