This Installation Guide
This installation Guide details the technical data, pinouts, and power connectivity of the Gold DC
Bell. For a comprehensive detailed description of the functions refer to the
MAN-G-Panel Mounted Drives Hardware manual which describes Panel Mounted products.
Chapter 2:
Safety Information
In order to achieve the optimum, safe operation of the Gold DC Bell, it is imperative that you
implement the safety procedures included in this installation guide. This information is provided to
protect you and to keep your work area safe when operating the Gold DC Bell and accompanying
equipment.
Please read this chapter carefully before you begin the installation process.
Before you start, ensure that all system components are connected to earth ground. Electrical
safety is provided through a low-resistance earth connection.
Only qualified personnel may install, adjust, maintain and repair the servo drive. A qualified person
has the knowledge and authorization to perform tasks such as transporting, assembling, installing,
commissioning and operating motors.
The Gold DC Bell contains electrostatic-sensitive components that can be damaged if handled
incorrectly. To prevent any electrostatic damage, avoid contact with highly insulating materials,
such as plastic film and synthetic fabrics. Place the product on a conductive surface and ground
yourself in order to discharge any possible static electricity build-up.
To avoid any potential hazards that may cause severe personal injury or damage to the product
during operation, keep all covers and cabinet doors shut.
The following safety symbols are used in this and all Elmo Motion Control manuals:
Warning:
This information is needed to avoid a safety hazard, which might cause bodily injury
or death as a result of incorrect operation.
Caution:
This information is necessary to prevent bodily injury, damage to the product or to
other equipment.
Important:
Identifies information that is critical for successful application and understanding of
the product.

Table of Contents
2.1. Warnings
•To avoid electric arcing and hazards to personnel and electrical contacts, never
connect/disconnect the servo drive while the power source is on.
•Power cables can carry a high voltage, even when the motor is not in motion. Disconnect
the Gold DC Bell from all voltage sources before servicing.
•The high voltage products within the Gold Line range contain grounding conduits for electric
current protection. Any disruption to these conduits may cause the instrument to become
hot (live) and dangerous.
•After shutting off the power and removing the power source from your equipment, wait at
least 1 minute before touching or disconnecting parts of the equipment that are normally
loaded with electrical charges (such as capacitors or contacts). Measuring the electrical
contact points with a meter, before touching the equipment, is recommended.
2.2. Cautions
•The maximum DC power supply connected to the instrument must comply with the
parameters outlined in this guide.
•When connecting the Gold DC Bell to an approved isolated auxiliary power supply, connect
it through a line that is separated from hazardous live voltages using reinforced or double
insulation in accordance with approved safety standards.
•Before switching on the Gold DC Bell, verify that all safety precautions have been observed
and that the installation procedures in this manual have been followed.
•Make sure that the Safe Torque Off is operational
2.3. CE Marking Conformance
The Gold DC Bell is intended for incorporation in a machine or end product. The actual end product
must comply with all safety aspects of the relevant requirements of the European Safety of
Machinery Directive 2006/42/EC as amended, and with those of the most recent versions of
standards EN 60204-1 and EN ISO 12100 at the least, and in accordance with 2006/95/EC.
Concerning electrical equipment designed for use within certain voltage limits, the Gold DC Bell
meets the provisions outlined in 2006/95/EC. The party responsible for ensuring that the
equipment meets the limits required by EMC regulations is the manufacturer of the end product.
2.4. Warranty Information
The products covered in this manual are warranted to be free of defects in material and
workmanship and conform to the specifications stated either within this document or in the
product catalog description. All Elmo drives are warranted for a period of 12 months from the date
of shipment. No other warranties, expressed or implied — and including a warranty of
merchantability and fitness for a particular purpose — extend beyond this warranty.

Chapter 3:
Product Description
The Gold DC Bell is an advanced high power density servo drive delivering up to 1.2 kW of
continuous power or 2.4 kW of peak power in a 230.075 cc (14.04 in³) package (115 x 75 x 26.4 mm
or 4.5" x 3.0" x 1.04").
This advanced, high power density servo drive provides top performance, advanced networking and
built-in safety, as well as a fully featured motion controller and local intelligence. The Gold DC Bell is
powered by a single 12 V – 195 V isolated DC power source (not included) and a “smart” control-
supply algorithm enables the drive to operate up to 95V with only one power supply with no need
for an auxiliary power supply for the logic.
The Gold DC Bell can operate as a stand-alone device or as part of a multi-axis system in a
distributed configuration on a real-time network.
The Gold DC Bell drive is easily set up and tuned using Elmo Application Studio (EAS) software tools.
As part of the Gold product line, it is fully programmable with the Elmo motion control language.
For more about software tools, refer to the Elmo Application Studio Software Manual.
The Gold DC Bell is available in a variety of options. There are multiple power rating options, two
different communications options, a variety of feedback selections and I/O configuration
possibilities.

Installation
The Gold DC Bell must be installed in a suitable environment and properly connected to its voltage
supplies and the motor.
5.1. Unpacking the Drive Components
Before you begin working with the Gold DC Bell, verify that you have all of its components, as
follows:
•The Gold DC Bell servo drive
•The Elmo Application Studio software and software manual
The Gold DC Bell is shipped in a cardboard box with Styrofoam protection.
To unpack the Gold DC Bell:
1. Carefully remove the servo drive from the box and the Styrofoam.
2. Check the drive to ensure that there is no visible damage to the instrument. If any damage
has occurred, report it immediately to the carrier that delivered your drive.
3. To ensure that the Gold DC Bell you have unpacked is the appropriate type for your
requirements, locate the part number sticker on the side of the Gold DC Bell. It looks like
this:
4. Verify that the Gold DC Bell type is the one that you ordered, and ensure that the voltage
meets your specific requirements.
The part number at the top provides the type designation. Refer to the appropriate part
number in the section Catalog Number at the beginning of the installation guide.
