Safety
2 Safety
2.1 Safety precautions
• Observe all safety and accident prevention regulations.
• Regularly check the proper observance off all safety measures.
• Do not loosen any plug connection during operations.
• Keep leads and cables well away from hot surfaces (> 70 °C).
• The unit has been accredited with protection class IP 65. When installing into
ambient conditions, which afford higher protection classes, the necessary
measures must be taken.
• Always ensure a safe connection to the protective earthing conductor (PE, pro-
tection class I).
• Before carrying out any work disconnect the unit and all associated installations
safely from the mains.
2.2 Proper use
• The relay box may only be used until the specified maximum contact load.
• The relay box may only be used to control vacuum backing pumps to Pfeiffer
Vacuum turbopumps with related electronic drive units.
• Permissible electronic drive units for the connection of the relay boxes are:
– integrated electronic drive unit TC 100 with TCS 010
– integrated electronic drive unit TC 600
– integrated electronic drive unit TC 750
– integrated electronic drive unit TM 3000 with connection cable PM 061 144 -X
– external electronic drive unit TCP 350 with connection cable PM 061 144 -X
2.3 Improper use
Improper use will cause all claims for liability and guarantees to be forfeited. Im-
proper use is deemed to be all use for purposes deviating from those mentioned
above, especially:
• The connection of a mains power voltage not corresponding to the rating plate
• Operation with contact loads higher than the information on the rating plate
NOTE
Duty to inform
Each person involved in the installation or operation of the unit must read and observe
the safety-related parts of these operating instuctions.
ÎThe operator is obligated to make operating personnel aware of dangers originating
from the unit or the entire system.
NOTE
CE conformity
The manufacturer's declaration becomes invalid if the operator modifies the original
product or installs additional components!
ÎFollowing installation into a plant and before commissioning, the operator must
check the entire system for compliance with the valid EU directives and reassess it
accordingly.
