UPC20+ Wiring Requirements
In the United States, the UPC20+ must be wired by an authorized electrician in
accordance with the National Electrical Code, ANSI/NFPA 70-1987, as well as all
local codes.
In the European community, the UPC20+ unit must be wired by an authorized electrician in accordance with all applicable European codes.
A readily accessible disconnect device shall be incorporated into the fixed wiring.
An insulated earthing conductor that is identical in size, insulation material and
thickness to be earthed and unearthed branch circuit supply conductors, except that
it is green with or without one or more yellow stripes, is to be installed as part of
the branch circuit which supplies the unit or system. The earthing conductor
described is to be connected to earth at the service equipment, or supplied by a
separately derived system, at the supply transformer or motor generator set.
The UPC20+ can also be controlled via the serial output from an AMX IR sensor. Remote sensor
mode is selected by setting jumper JP1 to the "Remote" position (jumper on the left 2 pins), as
shown in FIG. 3. (The jumper must be in position when power is applied to the UPC20+).

If motors of any kind are used, do not set to a Power Control mode. When a Power
Control mode is selected, both relays can be on at the same time. Motors can be
severely damaged if this happens.
osure
When controlled by a remote sensor, the UPC20+ is in 2, 3-button timer motor control mode. When
the timing potentiometer R8 adjusted to zero ohms (no time delay), the remote sensor provides
momentary control.
A 3-bit code (radio code) set on DIP switch S2 associates an AMX handheld remote control with a
UPC20+. This allows up to 8 UPC20+ and IR sensors to be used in the same room without
interfering with one another. It is possible to control 2 separate UPC20+'s with one handheld
remote control. The 4th switch of DIP switch S2 on the PCB selects between the two UPC20+'s.
The table below lists the results of the 16 possible DIP switch selections in remote sensor mode.

Installation
P1 Terminal Connections
Low voltage power (see the table below) for internal circuitry is provided from an on-board
transformer, powered by an external 120 or 240 VAC source. An onboard switch is used to select
input voltage. When using the UPC20+ for 277 VAC control, the on-board internal circuitry is
powered by a separate 120/240 VAC line, or from an optional 12 VDC power supply.

Installation
K1 and K2 are the power and motor control relay connections to P1 terminals 1 and 2, 3 and 4,
respectively. Each relay is capable of switching the following loads:
Resistive Load 20 Amps at 120/240 VAC
Fluorescent Ballast 6 Amps at 277 VAC
Inductive Load 1 HP
The maximum total combined current through both relays is 20 Amps. There are two 12-gauge
jumpers that are wired to supply board power at 120/240 VAC, and to connect the common
terminals of the relays. The jumpers are removed as needed according to the wiring options
selected.
