1. Overview
The WM-Nano is a compact table top automatic wrapper. The Uni-7 scale provides the operator
interface and prints labels that are applied to the wrapped package.
Refer to the Uni-7 Series Setup Manual to configure standard scale features such as
communications, label formats, etc.
2. Firmware
This document was written for WM-Nano firmware version B0684M.
3. Connections
Connect power and scales cables to the WM-Nano.
3.1. Power
The WM-Nano requires 220 VAC single-phase power. Using 3/12 power cable connect the 220
VAC input power as listed below. See Figure 3.1.
a. Green Ground
b. Black 120 VAC -- "L"
c. Black 120 VAC -- "N"
Caution: Measure and confirm voltage levels at the terminals before switching on the main
power.
Figure 3.1. WM-Nano Power Connections
3.2. Scale Cables
Connect the three Uni-7 scale cables as indicated below.
a. Power cord.
i. Connect the power cord at the socket under the WM-Nano wrapper next to the 220 VAC
power input. See Figure 3.1.
ii. Mount the "U" plate using two screws to secure the Uni-7 power cord. See Figure 3.2.

iii. Tip up the Uni-7 to access the bottom. Plug the power cord into the socket.
iv. Mount the "L" plate using two screws to secure the Uni-7 power cord. See Figure 3.3.
Figure 3.2. "U" Plate Securing Power Cord Figure 3.3. "L" Plate Securing Power Cord
b. Scale cable. Route the cable under the WM-Nano on the right side. A channel is provided to
prevent the cable from being damaged. Continue the cable up the rear of the wrapper and
under the Uni-7. Raise the door on the left side of the Uni-7 and connect the round snap-in
connector. Use the four cable clamps to secure the cable to the wrapper body.
c. Wrapper cable. Route the wrapper communication cable up the back of the machine. Tip up
the Uni-7 to access the bottom. Remove the metal access plate secured by two counter sink
screws. Connect the cable and mount the access plate. Use the cable clamps to secure the
cable. See Figure 3.4.

Film Roll widths from 16 to 22 inches may be used. The front and rear guides must be
set to properly align the roll.
a. Place the film roll on the two rollers at the upper left side. The film must come from
the bottom of the roll. See Figure 6.1.1.
Figure 6.1.1. Film Roll Setting on Rollers and Coming off the Bottom

Rev 3, B0684M, Oct 2012 7 WM-Nano_Setup
b. Adjust the Front Guide to align the front edge of the film with the edge of the
Support Roller. See Figure 6.1.2.
Note: For a 22-inch roll the film may overhang the front edge of the Polished
Roller if necessary.
Figure 6.1.2. Front Roll Guide and Film Alignment
c. Adjust the Rear Guide to prevent the roll from moving toward the back of the
wrapper. See Figure 6.1.3.
Notes: ●The roll must turn freely; the Guide roller should not touch the core.
Leave a 2mm gap between the core and the guide.
●The adjustment knob is accessed from inside from the front of the
wrapper.
Figure 6.1.3. Rear Roll Guide
6.1.2. Film Loading
