www.pulsar.pl PSCU 04344SEP 2. Installation. 2.1 Requirements. The power supply unit should be mounted by a qualified installer, holding relevant permits and licenses (applicable and required for a given country) for 230V/AC and low-voltage installations. The unit should be mounted in confined spaces, in accordance with the 2nd environmental class, with normal relative humidity (RH=90% maximum, no condensation) and temperature range from -10°C up to +40°C.
www.pulsar.pl PSCU 04344SEP 3. Optical indication. The PSU is fitted with 4 green L1÷L4 LEDs at the PCB, indicating DC voltage at the AUX1÷AUX4 outputs. During normal operation, the LED is permanently illuminated. In case of short-circuit or output overload, the LED is off. 4. Service and operation. 4.1 Overload or short-circuit of the power supply output (SCP activation). The AUX1÷AUX4 outputs of the PSU are individually protected against short-circuit by melting fuses.
