Information:
• The start/restart command must be installed outside the danger area in a position where the concerned
danger and entire working area are clearly visible.
• It must not be possible to reach the start/restart command from the inside of the danger area.
Attention:
Use in manual start mode is mandatory where the safety device controls an access protecting a danger
zone. This is to prevent a situation in which, once a person has passed through the opening, they could
remain in the danger zone without being detected. Failure to comply with this rule may result in serious
risks to people exposed.
