WIRING CONNECTIONS
The electrical connections are made via rear screw-clamp terminals located
on the back of the unit. When wiring the unit, use the label to identify the wire
position with the proper function. All conductors should meet voltage and
current ratings for each terminal. Also cabling should conform to appropriate
standards of good installation, local codes and regulations. It is recommended
that power supplied to the unit (AC or DC) be protected by a fuse or circuit
breaker. Strip the wire, leaving approximately 1/4" bare wire exposed
(stranded
wires should be tinned with solder)
. Insert the wire into the screw-clamp
terminal and tighten down the screw until the wire is clamped tightly. Each
terminal can accept up to two #14 AWG wires.
Note: The Reflective CUB4 will NOT have a screw terminal installed at the V+
terminal, since it is NOT required for operation and is not internally
connected. Refer to the Ordering Information for the part number of a
reflective model that will accommodate the MLPS.
Backlight Wiring
Optional backlight versions of the CUB4 require an external 9-28 VDC
power supply. The external supply is connected between the V+ and Common
terminals.
Warning:
Lithium battery may explode if incinerated.
Caution: All leads will be at the same line potential as the input leads.

L.S. INPUT, 30 CPS MAX.
The CUB4L8W accepts most machine control voltage signals. The input
accepts AC (50/60 Hz) or DC control voltages from 10 to 300 V at count
speeds up to 30 cps. The unit counts on the positive going edge of the input
signal.
WARNING
: Any lead may be at hazardous live input potential.
External wiring and devices connected to the unit must be rated
the same as applied signal input voltage and be properly
isolated from Class 2 or SELV circuitry.

RESET OPTIONS
Connecting a wire from the

Input terminal to
Common will enable the front panel Reset button. When Remote Reset is
required, a wire is connected from the “

can be pulled low by either a mechanical switch or solid-state transistor
switch. Switch load and leakage are the same as for “

Input above.
Note: The RC protection circuit on the “REM. RST.” Input causes a delay of
approximately 15 msec in Reset response.
BACKLIGHT OPTION
Optional backlight versions of the CUB4 require an external 9-28 VDC
power supply. The external supply is connected between the V+ and Common
terminals as shown in the drawing.
Red Lion Controls optional power supply (MLPS1000) is designed to be
attached directly to the rear of a CUB4 and is powered from a 85 to 250 VAC
source. The MLPS provides power for unit backlighting and a sensor.
WARNING
: When connecting the wiring for a backlit CUB4L8W
measuring an AC input voltage, the neutral of the single phase AC
signal is connected to Terminal 1 (COM), and line (hot) is
connected to Terminal 5 (LS). The DC supply for the backlighting
is connected as shown in the drawing. Three phase AC applications
require an isolation transformer.
