RelayWiringand“Jumper”Setting

m. Therearetworelays(Relay#1and#2,Figure3K)atthebottomrightofthecontrolcabinet.Relay

#1ontherightandrelay#2ontheleft.Thepurposeoftheserelaysistoturnonoroffanynon‐

criticalloadbeingmonitored,suchasapoolpumpthatcanbede‐energizedforshortperiodsin

ordertominimizedemandchargesfromtheutility.

n. The relays canbecontrolledbyoneof two TARAS

modules(Figure3K)and the “Jumper”setting(J25

andJ26justbelowTARASModule8)determine

whichTARAScardwillcontroltherelay.Relay“R1”

can be controlled by TARAS module 5 or 6. Relay

“R2”iscontrolledbyTARASmodule7or8.Typically,

the factory setting for the jumpers will be 5 (for

Relay1)and7(forRelay2).

o. ItisessentialthattheJumperissetsuchthattheCT

for that TARAS Module is monitoring the same

circuitthatisroutedthroughtherelay.Forexample,

iftheJumperforRelay1issetto6thenCT‐6should

beonthesameloadthatiswiredthroughRelay1.

p. Wiringviatherelaysrequiresonelegoftheloadto

bewiredfromthecircuitbreakerthroughtherelay

terminals (not shown, but plug directly into the

relay)andbacktotheloadbeingcontrolled.Extend

thecircuitwiringusingappropriatelyratedwire as

necessary. Terminal connectors will have to be
