Ambient temperature

The devices are suitable for an ambient temperature of 40 °C, max. 60 °C respectively 55 °C (Z.9 only) with derated output current. To determine the output current rating at higher than 40 °C, the output current should be derated 3.0 % per °C between 40 °C and 60 °C respectively 55°C (Z.9 only).

• Only use certified units with a limited output voltage (V_max = DC 30 V) and limited output current (I ≤ 8 A) as an external DC 24 V voltage source.
• The UL certification only applies for the operation on voltage supply systems with voltages to ground of max. 300 V. The UL-certification does not apply to operation on voltage supply systems with a non-grounded star point (IT systems).
