Make sure that the earth (ground) contact is attached when the unit is in operation.
Eagle Epac Controller Manual - 55 Fast Porn Swallowing Free Hardcore te co 2011 Traffic Signal Controllers: 4.21MB PDF Document: Siemens EPAC M50. Operation & Spare Parts Manual VERSION: EPAC. No plug‐in connections between Actuator and EPAC Controls.
A missing earth (ground) contact may lead to dangerous voltages in the housing and controls. Wireless microphones, mobile phones, etc.). Damage to the mainframe is unlikely, but cannot be excluded. To meet the EMC requirements, use only shielded cables with properly connected plugs for all signal terminals (INPUT, INPUT LINK, MIX IN).
E-PAC, Hardware manual (1.0E) Safety precautions-2 E-PAC, Hardware manual (1.0E) • This manual describes the facilities and functions of the hardware of the d&b E-PAC Power amplifier controller. A detailed description of the E-PAC Software and remote control is given in the E-PAC Software manual, which is also provided with the E-PAC.
• The E-PAC is specifically designed for high impedance loads (200 W into 16 ohms, 300 W into 8 ohms). If low impedance (LO IMP) mode is selected the E-PAC can drive up to two 8 ohm or four 16 ohm loudspeakers, at reduced output (–6 dB). • Digital Signal Processor (DSP), all necessary protection circuits, a remote interface, controls and indicators. The E-PAC is housed in a 2RU high, rugged enclosure and can be operated as a stand alone unit. Optional accessories allow single a E-PAC to be installed in standard 9.5' or 19' equipment racks or flightcases. • The E-PAC can deliver 200 W continuous sine wave output power into a 16 ohm load or 300 W into an 8 ohm load. Selecting low impedance mode enables the E-PAC to deliver an output power of 150 W into 4 ohms.
• 2 A (peak) at 230 V and 4 A (peak) at 115 V. The nominal operating range of the E-PAC is between 85 V and 265 V (100 V –15% /230 V +15%). Where voltages outside of. Game Prey Primal there.
• The REMOTE sockets can be used with either the dbCAN (CAN- Bus) interface or with a serial interface to the d&b Remote Interface Bridge (RIB) to integrate the E-PAC into a control and monitoring system. A detailed description of remote control via dbCAN (CAN-Bus) is given in the technical information TI312 (d&b code D5312.E.) • The power consumption is very low (2 W typical). − on: the E-PAC is switched on. Via remote or the MUTE control E-PAC Mains power switch the E-PAC can be switched to standby mode.
