General technical data

Interference immunity

Complies with EN 61800-3

Interference emission

Limit value class C2 according to EN 61800‑3.

The interference suppression level can be improved using appropriate measures. For more information, refer to chapter "Electrical installation" > EMC-compliant installation.

Ambient temperature ϑamb

See chapter Environmental conditions

Duty type

S1, continuous duty according to EN 60034‑1

Cooling by fan

  • Nominal output current up to 24 A: no
  • Nominal output current 32 A: optional
  • Nominal output current 46 A and higher: yes

Degree of protection

IP65 according to EN 60529:

  • Screw plugs for service unit tightened
    (tightening torque: 3.1 – 3.5 Nm)
  • All plug connectors with suitable protection cap or with connected cable

Pollution class

2 according to IEC 60664‑1

Overvoltage category

III according to IEC 60664-1

Permitted number of times power may be switched on/off

1 × per minute

Minimum switch-off time for power off

10 s

Required preventive measure

Grounding of the device

Installation altitude above sea level

No restrictions apply to altitudes < 1000 m.

The following restrictions apply to altitudes > 1000 m:

  • From 1000 m to max. 3800 m: IN reduction by 1% per 100 m
  • From 2000 m to max. 3800 m: To maintain protective separation and the air gaps and creepage distances according to EN 61800‑5‑1, an overvoltage protection device must be connected upstream to reduce the overvoltages from category III to category II.
