www.pulsar.pl EN54C-LCD RED POWER plus 4. Installation. 4.1. Requirements. The PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable and required for a given country) for ~230 V AC in and low-voltage installations. As the power supply is designed for a continuous operation and is not equipped with a powerswitch, therefore, an appropriate overload protection in the power supply circuit should be provided.
www.pulsar.pl EN54C-LCD 4.2. RED POWER plus Installation procedure. CAUTION! Before installation, cut off the voltage in the 230 V power-supply circuit. To switch power off, use an external switch, in which the distance between the contacts of all poles in the disconnection state is not less than 3mm. It is required to install an installation switch with a nominal current of 6 A in the power supply circuits outside the power supply unit. 1.
www.pulsar.pl 4.3. RED POWER plus EN54C-LCD Procedure for checking power supply at place of installation. 1 Check the indication displayed on the front panel of the power supply unit: a) The 230 V AC LED voltage. should remain lit to indicate the presence of the mains supply b) The LEDs AUX 1 and AUX 2 should remain lit to indicate presence of supply voltage. 2 Check the output voltage after 230 V power failure. a) Simulate the lack of 230 V mains voltage by disconnecting the main circuit breaker.
www.pulsar.pl EN54C-LCD RED POWER plus 5. Functions 5.1. Technical outputs. The power supply is fitted with relay indication outputs changing state upon the occurrence of a specific event. Fig. 6. Electrical diagram of relay outputs. EPS – output indicating 230 V power loss. The output indicates 230 V power loss. Under normal status – with the 230 V supply on, the output is closed. In case of power failure, the PSU will switch the output into the open position after a time 10s. (factory settings).
www.pulsar.pl EN54C-LCD RED POWER plus CAUTION! In Figure set of contacts shows a potential-free status of relay, which corresponds to power supply failure. 5.2. Input of collective failure: EXTi. The EXTi (external input) technical input indicating collective failure is intended for additional, external devices that generate the failure signal. Disconnection of the EXTi terminals will cause a failure of the PSU and generate a failure signal at the ALARM output.
www.pulsar.pl 5.3. EN54C-LCD RED POWER plus Indication of the enclosure opening – TAMPER. The PSU is fitted with the microswitch tamper indicating enclosure opening. The tamper cable is not connected to the terminal in the factory settings. In order to activate tamper, remove the jumper from tamper terminal and plug in the tamper cable.
