Observe the information on climatic conditions in chapter "Technical data" of the docu-
mentation.
2.7 Installation/assembly
Ensure that the product is installed and cooled according to the regulations in the doc-
umentation.
Protect the product from excessive mechanical strain. The product and its mounted
components must not protrude into the path of persons or vehicles. Ensure that com-
ponents are not deformed and that insulation spaces are maintained, particularly dur-
ing transportation. Electric components must not be mechanically damaged or des-
troyed.
Observe the notes in the chapter "Mechanical installation" of the documentation.
2.7.1 Restrictions of use
The following applications are prohibited unless explicitly permitted:
• Use in potentially explosive areas
• Use in areas exposed to harmful oils, acids, gases, vapors, dust, and radiation
• Operation in applications with impermissibly high mechanical vibration and shock
loads in excess of the regulations stipulated in EN61800-5-1
• Operation at installation altitudes above 4000 m above sea level
The product can be used at altitudes above 1000 m asl up to 4000m asl under the fol-
lowing conditions:
• Taking the reduced continuous rated current into consideration, see chapter
"Technical data" of the documentation.
• Above 2000 m asl, the air and creeping distances are only sufficient for over-
voltage class II according to EN60664. If the installation requires overvoltage cat-
egory III according to EN60664 you have to reduce the overvoltages on the sys-
tem side from category III to II using additional external overvoltage protection.
• If a protective electrical separation is required, then implement this outside the
product at altitudes of more than 2000m above sea level (protective separation in
accordance with EN61800‑5‑1 and EN60204‑1)
2.8 Electrical connection
Make yourself familiar with the applicable national accident prevention guidelines be-
fore you work on the product.
Perform electrical installation according to the pertinent regulations (e.g. cable cross
sections, fusing, protective conductor connection). The documentation at hand con-
tains additional information.
Make sure that all required covers are installed correctly after electrical installation.
Make sure that preventive measures and protection devices comply with the applic-
able regulations (e.g. EN60204-1 or EN61800-5-1).
2.8.1 Required preventive measure
Make sure that the product is correctly attached to the ground connection.

Safety notes
Protective separation
Operating Instructions – CMP ELVCD 11
2.9 Protective separation
The product meets all requirements for protective separation of power and electronics
connections in accordance with EN 61800-5-1. To ensure protective separation, all
connected circuits must also meet the requirements for protective separation.
2.10 Startup/operation
Observe the safety notes in the chapters "Startup" and "Operation" in the documenta-
tion.
Make sure that the present transport protection is removed.
Do not deactivate monitoring and protection devices of the machine or system even
for a test run.
Make sure the connection boxes are closed and screwed before connecting the sup-
ply voltage.
Depending on the degree of protection, products may have live, uninsulated, and
sometimes moving or rotating parts, as well as hot surfaces during operation.
Additional preventive measures may be required for applications with increased haz-
ard potential. You have to check the protection devices after each modification.
When in doubt, switch off the product whenever changes occur in relation to normal
operation. Possible changes are e.g. increased temperatures, noise, or oscillation. De-
termine the cause. Contact SEW‑EURODRIVE if necessary.
Mechanical blocking or internal safety functions of the product can cause a motor
standstill. Eliminating the cause of the problem or performing a reset may result in the
drive re-starting automatically. If, for safety reasons, this is not permitted for the drive-
controlled machine, first disconnect the product from the supply system and then start
troubleshooting.
Risk of burns: The surface temperature of the product can exceed 60°C during opera-
tion.
Do not touch the product during operation.
Let the product cool down before touching it.

• Thoroughly remove any anti-corrosion agent from the shaft end. Use a commer-
cially available solvent. Do not allow the solvent to penetrate the bearings and
sealing rings – this could damage the material.
• Align the motor carefully to avoid placing any unacceptable strain on the motor
shafts. Observe the permitted overhung and axial loads specified in the gear unit
catalog.
• Do not jolt or hammer the shaft end.
• Ensure sufficient clearance around the unit to allow for adequate cooling air sup-
ply. Warm outlet air of other units must not affect the cooling.
• Balance components that were subsequently mounted to the shaft with a half key
(output shafts are balanced with a half key).
• Use suitable cable glands for the supply leads (use reducing adapters if neces-
sary).
• Seal the cable entry properly.
• If the corrosion protection coating is damaged, restore the coating.
• Check whether the degree of protection specified in the operating instructions and
on the nameplate is permitted in the ambient conditions on site.

ELVCD drives are supplied in corrosion-resistant design for use in damp areas or in
the open.
Repair damage to the paint work.
Condensation is not permitted for ELVCD drives.
4.5.4 Painting the ELVCD drive
NOTICE
Breather valves and oil seals may be damaged during painting or re-painting.
Possible damage to property.
