LTPH-UM-1088-02, Issue 2Installation

Field-Effect Transistor (MOSFET). When set to ON, resistance is 35Ω at 85°C (worst case). The switched current must be less than 80 mA, and the switched voltage must be less than 135V. If a coil relay or other inductive load is used, a protection diode must be connected between the alarm signal and the COM signal to prevent damage to the solid state relay. ADC does not provide the diode with the ThinMux chassis. The diode must be purchased separately. Use Motorola diode part number 1N4004 or equivalent.

BATTERY SUPPLY

The battery supply terminals are located on the rear of the chassis under the common access panel (see Figure 1 on page 2). Five AWG 16 wires connect the Return B, -48B, Return A, -48A, and Frame Ground to the power source. To wire power A and B inputs, attach A and B power leads from the fuse panel or office battery to the appropriate screw connector on the terminal block. For more information, refer to “Connecting Power” on page 10.

INSTALLATION

Before installing the ThinMux Chassis, visually check its packaging to ensure that it has sustained no shipping damage. Immediately report any damage to the shipping agent. See “Appendix C - Product Support” on page 19.
