GOODRICH Stormscope Series II Installation Manual page 25

NOTES
NORMALLY THE INHIBIT LINE IS NOT NEEDED IF THE
1.
STORMSCOPE ANTENNA AND THE COMMUNICATIONS
ANTENNAS ARE ON OPPOSITE SIDES OF THE AIRCRAFT
FUSELAGE. IF THE INHIBIT LINE IS CONNECTED TO MULTIPLE
MICROPHONE SWITCH LINES, EXTERNAL ISOLATION DIODES
MUST BE INSTALLED BETWEEN THE SWITCH LINES AS
SHOWN.
2.
THE WX-950 IS PROTECTED VIA AN INTERNAL FUSE (SEE
PARA 4.7). FOR EXTERNAL CIRCUIT BREAKER PROTECTION,
A 5 A CIRCUIT BREAKER IS RECOMMENDED FOR 14 V
AIRCRAFT SYSTEMS AND A 3 A CIRCUIT BREAKER FOR 28 V
3. SYSTEMS.
THE SECOND SHIELDED PAIR CABLE (CONNECTED TO PINS
20 AND 21) IS NECESSARY ONLY IF POWER CABLE LENGTH IS
4. GREATER THAN 15 FEET.
OPTIONAL REMOTE CLEAR SWITCH PROVIDES THE SAME
FUNCTION AS SOFTKEY B.
5.
INTERNAL AND EXTERNAL SHIELDS ARE ISOLATED FROM
EACH OTHER. DO NOT CONNECT THESE SHIELDS
TOGETHER.
