ELECTRICIAN’S NOTES
(PROBE WIRING) SHIELDED WIRE AWG #22 WITH 16/30 STRANDING, 500ft
(150m) MAXIMUM LENGTH (Ex.: DECA 73-310).
For other probe, refer to specific probe manual for appropriate maximum length and
wire size or use AWG #22, 500ft (150m) MAXIMUM LENGTH.
(COMMUNICATION WIRING) SHIELDED, TWISTED PAIR (8 TWIST/FT). MAX
LENGTH FOR 350PF/M CABLE : 500FT (150M). MAX LENGTH FOR 89PF/M
CABLE : 820FT (250M).
HIGH VOLTAGE WIRE INSTALLED ACCORDING TO LOCAL WIRING CODE.
INSTALL LOW VOLTAGE WIRES (PROBES, COMPUTER LINK OR
POTENTIOMETER WIRES) AT LEAST 12 INCHES (30cm) AWAY FROM HIGH
VOLTAGE WIRES (120/230VAC, 24VDC). ALWAYS CROSS HIGH AND LOW
VOLTAGE WIRES AT A 90-DEGREE ANGLE.
RELAYS : 20A @250 VAC RESISTIVE, MOTOR 2HP @250 VAC, 1HP 120 VAC
AT EACH OUTPUT.
TRIAC : THE CURRENT SHALL NOT EXCEED 8A AT EACH OUTPUT. SEE
SPECIFICATIONS SECTION FOR DETAILS.
MAXIMUM 2 WIRES OF SAME SIZE PER BLACK TERMINAL, NO BIGGER
THAN AWG #12, NO SMALLER THAN AWG #22.
1 WIRE ONLY PER GREEN TERMINAL. USE WIRE CONNECTOR IF YOU
WANT TO CONNECT MORE THAN 1 WIRE, NO BIGGER THAN AWG #12, NO
SMALLER THAN AWG #28.
CHECK INSTALLATION SECTION FOR ALARM WIRING.
USE SHIELD FOR SHIELDING PURPOSE ONLY. CONNECT 1 END AND 1 END
ONLY OF THE SHIELD TO THE CONTROL CIRCUIT COMMON END . NEVER
LEAVE BOTH ENDS OF THE SHIELD UNCONNECTED. NEVER CONNECT
BOTH ENDS OF THE SHIELD TO COMMON . THE USE OF A SHIELD FOR
ALL PROBES AND POTENTIOMETERS IS MANDATORY.
JP1 - JUMPER MUST BE INSTALLED ON PIN 2-3 = STANDARD AND
JP2 - JUMPER MUST BE INSTALLED ON PIN 2-3 = STANDARD
THE CURRENT SHALL NOT EXCEED 13.5A AT EACH OUTPUT (OUT 1-2) FOR
A RESISTIVE LOAD (LIGHTS) AND FOR AN INDUCTIVE LOAD (FANS), THE
CURRENT SHALL NOT EXCEED 12A AT EACH OUTPUT (OUT 1-2).
VARIABLE BOARD (X1279) OF THE V4 MODULE REQUIRES THE SAME
PHASE AND VOLTAGE AS THE MODULE MAIN BOARD (X1335).
