BEFORE INSTALLATION Protection against shock: Software class: IMPORTANT It is recommended that the Excel 12 be kept at room temperature for at least 24 hours before applying power; this is to allow the evaporation of any condensation resulting from low shipping / storage temperatures. Class 0 (without terminal covers) Class II (with terminal covers) Class A Classification according to EN60529 (Degree of Protection Provided by Enclosures) Without terminal covers: IP20 With terminal covers: IP30 CAUTION To avoid electrical shock or equipment damage, you must turn off the power supply before attaching / removing connections to/from any terminals.

[. . . ] separation of 3 inches (76 mm) between such cables. Local wiring codes may take precedence over this recommendation. IMPORTANT Try to avoid installing in areas of high electromagnetic noise (EMI). The unit must be wired to the LONWORKS network using level IV 22 AWG (Belden part number 9D220150) or plenum-rated level IV 22 AWG (Belden part number 9H2201504) nonshielded, twisted-pair, solid-conductor wire. When possible, use Honeywell AK3781, AK3782, AK3791, or AK3792 cable (US part nos. ). See Excel 50/5000 LonWorks Mechanisms, EN0B-0270GE51, for details, including max. The unit is connected to the LONWORKS network as shown in Fig. 9 via terminal pins 3 and 4 (black screw-type T terminal plug) underneath the terminal protection cover (if present) located on the low-voltage side. Terminal 24 and 25 are used to connect further devices to the LONWORKS network. Connection of CO2-Sensor A CO2-sensor (e. g. C7110D1009) may be connected to analog inputs 1, 5, or 7 for air-quality control. W7704 TEMP.

LonWorks Communications The Excel 12 is equipped with a free-topology transceiver (FTT10A) for communicating on LONWORKS® networks. The LONWORKS network is insensitive to polarity, eliminating the possibility of installation errors due to miswiring. Different network configurations (daisy-chain, loop, and star configurations, or any combination thereof) are possible (see also Excel 50/500 LONWORKS Mechanisms Interface Description, EN0B-0270GE51). All Excel 12 controllers feature a LONWORKS service LED and service button (see section "Troubleshooting" on page 6). General Information Inputs/Outputs Use a min. of 14 AWG (2. 5 mm2) for all input/output connections. length of all input/output cables is 1300 ft (400 m). Two wires with a total thickness of 14 AWG can be twisted together and connected using a wire nut (include a pigtail with this wire group and attach the pigtail to the individual terminal block). Deviations from this rule can result in improper electrical contact. Local wiring codes may take precedence over this recommendation. Wire to the terminal blocks as follows: Wiring the Inputs/Outputs 5 EN1B-0201GE51 R0110F EXCEL 12 MODULES 1. Insert it at the required terminal location, and tighten the screw to complete the termination. [. . . ] LED flashes at power-up, goes OFF, then comes ON solid. Afterwards, the service LED turns ON and remains ON, indicating completion of the blanking process. Afterwards, the service LED turns ON and remains ON. OFF duration is 1. . . 15 sec, depending on the application size and the system clock. [. . . ]
