2.2 Residual hazards
Protection of persons
ƒ Before working on the power supply module, check that all power terminals are
deenergised
– because the power terminals L1, L2, L3, +UG, -UG, Rb1, Rb2, X109 and X110 carry
hazardous voltages for at least 3 minutes after mains disconnection.
– because the power terminals carry hazardous voltages even when only the mains
voltage is applied.
Device protection
ƒ Connect/disconnect all pluggable terminals only in deenergised condition!
ƒ Detach the power supply modules from their installation backplanes only in
deenergised condition!
ƒ The unit only functions properly when the 24 V supply is switched on!
