ENGLISH
Observe the following precautions for MCC units shipped to the site as a
plug-on unit.
• Lifting plug-on units taller than 24 in. (610 mm) require two or more
persons using special handling precautions and lifting devices.
• If lifting devices are used, refer to Figure 6 for proper lifting points.
Before installing any MCC control units, locate and retighten or retorque any
connections that may have loosened during shipment and handling. Refer
to the procedures in “Installing Additional MCC Units” on page 95 of this
instruction bulletin.
Storing the MCC

dry, ventilated building free from temperature extremes. Acceptable storage
temperatures are from 0 °C (32 °F) to 40 °C (104 °F). Acceptable humidity
levels are 0–95%, non-condensing.
If the storage area is cool and/or damp, provide enough heat to prevent
condensation inside the MCC. Contact your Schneider Electric field sales
representative for specific requirements.
