HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
If signs of moisture contamination are present, do not
follow the instructions in this section; proceed Moisture Contamination Avoidance and Mitigation.
Failure to follow these instructions will result in death or serious injury.
|
Receiving
Upon receipt, check the packing list against the equipment received to ensure the order and shipment are complete. Also, upon receipt, immediately inspect switchboard sections for any damage that occurred in transit. If damage is found or suspected, file a claim with the carrier immediately and notify the nearest Schneider Electric representative.
Handling
NOTICE |
---|
Hazard of Equipment Damage
Failure to follow these instructions can result in equipment
damage.
|
Ensure that proper equipment, such as an overhead crane, is available at the installation site to handle the switchboard. This equipment helps avoid injury to personnel and damage to the switchboard.
The shipping weight of each shipping section is marked on the packing list. Verify the lifting capacity of the equipment being used to handle the switchboard in accordance with the shipping weight of each shipping section. Keep the switchboard upright during handling.
Schneider Electric recommends using an overhead crane, lifting straps, and cables or chains to handle the switchboard. This method and alternative handling methods are discussed in this section.
Handling with Lifting Straps
Schneider Electric provides lifting eyes as standard equipment for NEMA Type 1 FlexSeT switchboards. Instruction labels on each shipping section include drawings and written instructions outlining the proper use of the lifting straps (see Lifting with an Overhead Crane, Lifting Straps, and Cables or Chains). Use rigid spreaders or a spanner bar to provide vertical lift on the lifting straps. This helps avoid damage to the frame or finish.
Follow these instructions to handle the switchboard:
- When attaching lifting straps to the switchboard, assemble the hardware in the order shown in Hardware Assembly Order.
- Use load-rated cables or chains with safety hooks* or shackles. Do not pass cables or chains through holes in lifting straps.
- Use a load-rated spreader beam to help prevent structure damage. Rig so that the minimum angle between the lifting cables or chains and equipment top is 45°.
Handling without Lifting Straps
Lifting eyes are not furnished on skid mounted or outdoor subassembly. Use rollers, slings, or other means to handle the shipping sections. The handling label (see Handling Instruction Label-Switchboards without Lifting Straps) is affixed to each of these sections.

Hazard of TOP HEAVY LOAD-TIPPING
Failure to follow these instructions can result in death,
serious injury, or equipment damage.
|
When elevating a shipping section not equipped with lifting eyes, use an overhead crane equipped with either of the following:
- A chain coupled to a sling rigging. Wrap the sling completely around the switchboard and shipping stringers.
- A wire cable with safety hooks and shackles.
A forklift is an alternative method of handling the switchboard. Before using a forklift:
- Read the fork access labels on the switchboard sections (see Handling with a Forklift).
- Check the fork lengths to ensure the forks extend under the entire switchboard.
- Carefully balance the load.
- Use a strap when handling or moving a switchboard with a forklift.
Storage
When storing the switchboard before installation, cover the top and openings of the equipment during the construction period to help protect the switchboard from dust and debris.
If a switchboard is not installed and energized immediately, store it in a clean, dry space with a consistent temperature to help prevent condensation. Store the switchboard indoors, if possible. Preferably, store it in a heated building with adequate air circulation and protect it from dirt, fumes, water, and physical damage. Storing the switchboard outdoors can cause harmful condensation inside the switchboard.
Before energizing the space heaters, remove all loose packing or flammable materials inside the switchboard. Outdoor switchboards are not weather-resistant until completely and properly installed; treat them the same as indoor switchboards until after installation.
