Electrical Installation
The Mercury is available in two different wiring versions: terminal block,
or wiring cable. The following instructions apply to cable versions.
Terminal Block versions include an additional wiring information label
adjacent to the terminal blocks inside the unit enclosure.
The Mercury includes two separate wiring cables for Main Power and
Input Trigger Signal connections. These cables may route through either
one or two conduit fittings, as required.
Main Power
Main Power is a universal power input that accepts any AC voltage
from 90-249 VAC, 50/60 Hz. Typical sources include a wall outlet, or
washing machine incoming power terminals. For wall outlet connections
use a wall plug, sourced locally, that fits outlets in your region. Main
Power Cable color coding is as follows: Blue + Brown 90-249 VAC,
50/60 Hz.
NOTE:
In cases where a Neutral wire exists, connect Neutral to
the Blue wire.
Green with yellow stripe is Earth Ground.
Trigger Signal Wiring
All trigger signal inputs are optically isolated high impedance input circuits. Washer supply signal voltages
may range from 24-249 VAC, 50/60 Hz (20 mA maximum draw) or 12-24 VDC (5 mA maximum draw) that
accommodate the range typically found in most washing machines. Each signal input connects to a pair of signal
input wires (solid color and white with colored stripe). In cases where the washing machine has a single
common for supply signals, connect all the signal input common wires (white with colored stripes) to the machine’s
signal common wiring location. In Automatic or Relay Mode trigger inputs match pump numbers (i.e. trigger 1 =
pump 1, etc.). In Occurrence Mode connect wire pairs from each machine fill valve to two trigger inputs (it does not
matter which two of the three available trigger inputs are used for Occurrence Mode).
Signal Input wire colors are as follows:
Trigger Signal 1 = Black
Signal Common 1 = White w/Black Stripe
Trigger Signal 2 = Brown
Signal Common 2 = White w/Brown Stripe
Trigger Signal 3 = Red
Signal Common 3 = White w/Red Stripe
Auto Formula Select Wiring
Input specifications are the same as trigger inputs. The Auto Formula Select signal must be programmable to the
second on the washing machine control system. Program the washer to send this signal at the start of the wash
load (prior to any chemical supply signals) for a duration of 2 seconds times the desired formula number (i.e. for
formula 2 program for 2s * F2 = 4 seconds signal time).
Auto Formula Select input wire colors are as follows:
Auto Formula Select Signal = Orange
Auto Formula Select Signal Common = White w/Orange
CAUTION:
The Mercury dispensing system
is intended to be installed
by experienced installers in
accordance with all applicable
electrical and plumbing codes.
All laundry machine and dispenser
power is to be disconnected
during installation and/or any time
the dispenser cabinet is opened.
CAUTION:
Always verify all voltage sources
with a meter.
NOTE:
Failure to use watertight conduit
for electrical cables will impair
water resistance of the
unit enclosure.
