ThinMux Chassis January 3, 2002 5
Field-Effect Transistor (MOSFET). When set to ON, resistance is 35at
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 Supporton page 19.
