6.2 Ensuring the degree of protection
Only the mechanical and electrical connections which are described in these instructions
and which are necessary for the required, designated use, may be carried out on the device
delivered.
‣
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
