Exercise care when carrying out the work.
Individual types of protection permitted for this product (impermeability (IP), electrical
safety, EMC interference immunity) can no longer be guaranteed if, for example :
• Covers are left off
• Different power units to the ones supplied are used
• Cable glands are not sufficiently tightened (must be tightened with 2 Nm (1.5 lbf ft) for
the permitted level of IP protection)
• Unsuitable cable diameters are used for the cable glands
• Modules are not fully secured
• The display is not fully secured (risk of moisture entering due to inadequate sealing)
• Loose or insufficiently tightened cables/cable ends
• Conductive cable strands are left in the device
