Residual hazards

1.2 Residual hazards
Protection of persons
Before working on the power supply module, check that no voltage is
ƒ
applied to the power terminals,
–
the power terminals +UG, −UG, BR0 and BR1 remain live for at least 3
minutes after mains disconnection.
–
because the power terminals +UG, −UG, BR0 and BR1 remain live when
the motor is stopped.
The operating temperature of the heatsink can exceed 70 °C:
ƒ
–
Direct skin contact with the heatsink results in burns!
The leakage current to PE is > 3.5 mA AC or > 10 mA DC. Therefore, two PE
ƒ
connections are installed for protective reasons.
–
Comply with the requirements of EN 61800−5−1 for high leakage
currents!
For operation of the power supply module with an earth−leakage circuit
ƒ
breaker:
–
The power supply modules are provided with an internal mains
rectifier. In the event of a short−circuit to frame, a non−pulsating DC
fault current can prevent the tripping of AC−sensitive or
pulse−current−sensitive earth−leakage circuit breakers and thus block
the protective function for all electrical equipment operated on these
earth−leakage circuit breakers.
–
If a residual current device (RCD) is used as a protective means in the
case of direct or indirect contact, only a residual current device (RCD) of
type B may be used. Otherwise, another protective measure, such as
separation from the environment through double or reinforced
insulation or disconnection from the mains by means of a transformer
must be used.
Device protection
The power supply module may only be driven from balanced mains
ƒ
supplies. Mains supplies with earthed phase are not permitted.
Observe the max. permissible mains voltage. Higher voltages will damage
ƒ
the power supply module.
The power supply module contains electrostatic sensitive devices. The
ƒ
personnel must be free of electrostatic charge prior to assembly and
service operations.
All pluggable connection terminals must only be connected or
ƒ
disconnected when no voltage is applied!
The power terminals +UG, −UG and PE are not protected against polarity
ƒ
reversal.
–
When wiring, observe the polarity of the power terminals!
