CONNECTING THE BUS IN NOISY ENVIRONMENTS
When installing the bus wires in proximity to high electrical interference such as neon lights, motors, high-voltage wiring, transf orme rs, o r if co nn ectin g the
bu s acr oss sepa rate bu ildings, you must use shielded cab le s. Con ne ct th e shielde d cable as det ailed be low:
Within the Same Building: Strip t he ou te r jacket at o ne en d of th e sh ielde d cab le t o e xpo se the sh ie ld and co nn ect th e sh ield to th e co nt ro l pa ne l gr ou nd
(not the d ia ler grou nd ), while le aving th e sh ie ld at th e oth er en d of t he cab le open (floa ting ).
Across Separate Buildings: Strip th e o ute r jacket at one en d of th e shielde d ca ble to e xpo se t he shield . In the same bu ild ing t hat ho use s the con trol pa nel,

BUILT-IN RTC
Dig iplexNE inco rporate s a n RTC directly on th e PC boa rd. The RTC will save DigiplexNE ’s inte rn al clock wh en b oth t he AC an d ba tter y po wer have be en
lost. After power is lost and then restored, DigiplexNE will verify with and then retrieve the time from the RTC. The control panel will verify and compare its
time with the time stored in the RTC every hour. If the times a re diff erent, DigiplexNE will reset its internal clock to the time saved in the RTC. The RTC uses
a 3 V lith ium batte ry ( CR20 32) with a b at tery life o f 11 yea rs. Cha nge th e b at tery a s sho wn b elow:
