JADE™ ECONOMIZER MODULE

Economizer Module Wiring Method
Wire the sensors and outputs, then wire the power
connection.
Each terminal can accommodate the following gauges of
wire:
• Single wire – from 18 AWG to 22 AWG solid or stranded
• Multiple wires – up to two 22 AWG stranded
• For the 24 Vac connections: single wire – from 14 to 18
AWG solid or stranded
• For S-BUS wiring, the sensors may be mounted up to
200 ft. (61 m) from the JADE controller. When the
length of wire is over 100 feet use twisted pair shielded
wire.
• All sensor wiring to the Sylk bus and analog sensors is
polarity insensitive.
Prepare wiring for the terminal blocks, as follows:
1.
Remove the plastic tabs from the side of the control-
ler where the connectors will slide onto the PWA.
2.
Strip 1/2 in. (13 mm) insulation from the conductor.
3.
Cut a single wire to 3/16 in. (5 mm). Insert the wire in
the required terminal location and tighten the screw.
4.
If two or more wires are being inserted into one
terminal location, twist the wires together a
minimum of three turns before inserting them to
ensure proper electrical contact. See Fig. 5 on
page 6.
5.
Cut the twisted end of the wires to 3/16 in. (5 mm)
before inserting them into the terminal and
tightening the screw.
6.
Pull on each wire in all terminals to check for good
mechanical connection.

JADE™ Economizer Module Wiring
Use Fig. 6 and Tables 1 and 2 to locate the wiring
terminals for the Economizer module.
NOTE:
The four terminal blocks are removable. You can
slide out each terminal block, wire it, and then
slide it back into place.

1. STRIP 1/2 IN. (13 MM)
FROM WIRES TO
BE ATTACHED AT
ONE TERMINAL.
2. TWIST WIRES
TOGETHER WITH
PLIERS (A MINIMUM
OF THREE TURNS).
3. CUT TWISTED END OF WIRES
TO 3/16 IN. (5 MM) BEFORE INSERTING
INTO TERMINAL AND TIGHTENING SCREW.
THEN PULL ON EACH WIRE IN ALL
TERMINALS TO CHECK FOR
GOOD MECHANICAL CONNECTION.
