7.2.2 Safety instructions
WARNING
Danger to life through non-observance of the safety instructions
If the safety instructions in Chapter 1 are not observed, accidents can occur involving
severe injuries or death.
• Make sure that the safety instructions are observed.
WARNING
Risk of fire through overheating if there are insufficient ventilation clearances
Inadequate ventilation clearances cause overheating with a risk for personnel due to smoke
and fire. This can also result in more downtimes and reduced service lives of the Terminal
Module.
• For this reason, it is imperative that you maintain the 50 mm clearances above and
below the Terminal Module.
NOTICE
Shield support
When the encoder system is connected via terminals, make sure that the cable shield is
connected to the component.
NOTICE
Device failure as a result of unshielded or incorrectly routed cables to temperature sensors
Unshielded or incorrectly routed cables to temperature sensors can result in interference
being coupled into the signal processing electronics from the power side. This can result in
significant disturbance of all signals (fault messages) up to failure of individual components
(destruction of the devices).
• Only use shielded cables as temperature sensor cables.
• If temperature sensor cables are routed together with the motor cable, use separately
shielded cables twisted in pairs.
• Connect the cable shield at both ends to ground potential over a large surface area.
