Siemens PSC-12 12 Amp Power Supply for NCCNT WAN, Installation Instructions

Installation Instructions PSC 12 Amp Power Supply for NCCNT WAN Model PSC 12 from Siemens Industry Inc is a high current power supply that the system with primary regulated 24VDC It is rated at 12A and has a built charger that is capable of charg up to 100AH batteries It also a microprocessor controlled circuit that allows the PSC to switch the system power to batteries during loss or of the AC power PSC 12 incorporates an 18A breaker on the battery input provides terminal tie points for signals PSC 12 mounts at the back of enclosure of the COM 1 and one location on the studs the backbox or on the optional Mounting Plate PSC 12 has four programmable The relays can be configured the NCC WAN to change state on global alarm a global trouble or on a manual request general output 1 12 Amp Power Supply PSC 12 features are as follows AC power input 120VAC 240VAC 60Hz 50Hz Switch Mode Power Converter Factor Correction Battery Charger Output power of 12A 24VDC separate power output terminals one power limited terminal with 4A 24VDC capacity and one non power limited terminal with 12A max 24VDC capacity total not to exceed 12A output terminals have current measurement capability

circuit to improve conductive RF emission at low frequency It is designed take voltage inputs of 120VAC 240VAC at 50Hz 60Hz and has one resettable breaker that can also be used as a battery power switch Charger monitors and maintains the battery This circuitry utilizes three charge depending upon the state of the batteries Bulk Full Charge State Trickle State and Float maintenance State The Charger monitors the batteries and which of the charging modes to activate It also has the capability to the state of the battery through diagnostic testing Blocks and Indicators PSC 12 has one reset switch seven LEDs three address switches one circuit four terminal blocks four terminal connections and two 60 pin flat ribbon as shown in Figure 2 reset switch is located on the top of the front panel Pushing the reset switch re the PSC 12 operation LEDs located at the top left of the module are defined as follows or Blue Normally ON When illuminated indicates FAIL FAIL FAIL FAULT the PSC 12 is powered from the AC When flashing indicates that the is powered from the battery OFF When illuminated indicates the module microprocessor has failed OFF Not used in this applica OFF When illuminated indicates the HNET communication with the has terminated and the card goes degrade mode applicable only when card resides in the HNET network OFF When illuminated indi that the PSC 12 has detected a negative or positive ground fault its outputs Industry Inc Technologies Division 315 099321 7 NOT NOT NOT NOT NOT 12A FAIL Yellow 4A FAIL OFF When illuminated indicates the 24VDC non power

as follows refer to Figure 2 Currently NOT USED Outputs Four user programmable relays that are set to USED by default These outputs are rated 2A 30VDC 6PF Refer to Figure 3 for wiring the relays relays are controlled by the NCC WAN only NCC WAN 6.01.007 or higher is required The relays can be config in the NCC WAN as Global Alarm Global Trouble or Output relay configured as Global Alarm changes the respective PSC state to off normal when there is any alarm on the NCC all alarms are cleared on the NCC the relay state will to normal relay configured as Global Trouble changes the respective relay state to off normal when there is any trouble on the When all troubles are cleared on the NCC the relay state restore to normal relay configured as General Output will change state

Division 315 099321 7 NOT USED Non Power Limited Output Terminal This terminal is non power and can supply up to 12A When the current draw is exceeded it down lights its associated LED and sends a fault condition to the WAN output is normally connected to the input terminals of the CC 5 output must remain within the enclosure or within 20 feet in rigid All wiring must be in accordance with Article 760 of NEC or building codes See Figure 2 Voltage 24VDC 10 15 Current 12A max terminal terminal total cumulative sum of the 24VDC output power limited non power limited not exceed 12A Over current draw will initiate a PSC 12 shut down The main AC power line must be turned OFF prior to installation apply AC power first followed by the battery NOT USED P4 contains a factory installed plug Do not the plug from P4 NOT USED the back up battery to the PSC 12 Battery size has to be to ensure that the battery size can support the system load battery back up condition Refer to the Battery Calculation form to the required battery size of the system the jumper on P10 to ENABLE left hand position to enable ground protection input connector from the PTB terminals P4 or P5 the PSC 12 to the system It is a straight through connection the two connectors and provides the 24VDC rated at 2A and rated at 2A that powers the CC 5 modules It also contains all communication signals and system
