Publication 1756-IN580A-EN-P - March 2003

Environment and Enclosure

Prevent Electrostatic Discharge

ATTENTION

This equipment is intended for use in a Pollution Degree 2 industrial

environment, in overvoltage Category II applications (as defined in

IEC publication 60664-1), at altitudes up to 2000 meters without

derating.

This equipment is considered Group 1, Class A industrial equipment

according to IEC/CISPR Publication 11. Without appropriate

precautions, there may be potential difficulties ensuring

electromagnetic compatibility in other environments due to

conducted as well as radiated disturbance.

This equipment is supplied as "open type" equipment. It must be

mounted within an enclosure that is suitably designed for those

specific environmental conditions that will be present and

appropriately designed to prevent personal injury resulting from

accessibility to live parts. The interior of the enclosure must be

accessible only by the use of a tool. Subsequent sections of this

publication may contain additional information regarding specific

enclosure type ratings that are required to comply with certain

product safety certifications.

See NEMA Standards publication 250 and IEC publication 60529, as

applicable, for explanations of the degrees of protection provided by

different types of enclosure. Also, see the appropriate sections in this

publication, as well as the Allen-Bradley publication 1770-4.1

("Industrial Automation Wiring and Grounding Guidelines"), for

additional installation requirements pertaining to this equipment.

ATTENTION

This equipment is sensitive to electrostatic discharge, which can

cause internal damage and affect normal operation. Follow these

guidelines when you handle this equipment:

·Touch a grounded object to discharge potential static.

·Wear an approved grounding wriststrap.

·Do not touch connectors or pins on component boards.

·Do not touch circuit components inside the equipment.

·If available, use a static-safe workstation.

When not in use, store the equipment in appropriate static-safe

packaging.

Removal and Insertion Under Power

Repeated electrical arcing causes excessive wear to contacts on both

the module and its mating connector. Worn contacts may create

electrical resistance that can affect module operation.

The Hydraulic Servo Module (1756-HYD02) mounts in a

ControlLogix™ chassis and uses a removable terminal block (RTB) to

connect all field-side wiring.

Before you install your module you should have:

·installed and grounded a 1756 chassis and power supply.

·ordered and received an RTB and its components for your

application.

Note the Power Requirements

This module receives power from the 1756 chassis power supply and

requires two sources of power from the backplane:

·700mA at 5.1 V dc

·2.5 mA at 24V dc

Add this current to the requirements of all other modules in this

chassis to prevent overloading the backplane power supply.

WARNING When you insert or remove the module while backplane

power is on, an electrical arc can occur. This could cause

an explosion in hazardous location installations. Be sure

that power is removed or the area is nonhazardous

before proceeding.

ControlLogix™ Hydraulic Servo Module 5

Publication 1756-IN580A-EN-P - March 2003

Identify Module Components

You received two components with your order:

·1756-HYD02 module

·RTB door label

If you did not receive these components, contact your Rockwell

Automation representative.

This module mounts in a 1756 chassis and uses a separately-ordered

RTB or a Bulletin 1492 Interface Module (IFM)(1) to connect all

field-side wiring. This module uses one of the following RTBs:

·1756-TBCH 36 position Cage clamp RTB

·1756-TBS6H 36 position Spring clamp RTB

Use an extended-depth cover (1756-TBE) for applications with heavy

gauge wiring or requiring additional routing space. When using an

IFM, consult the documentation that came with it to connect wiring.

(1) The Bulletin 1492 IFM may not be used in any application that requires agency certification of the

ControlLogix system. Use of the IFM violates the UL, CSA and FM certifications of this product.

IMPORTANT Before you install your module, you should:

·install and ground a 1756 chassis and power supply.

·order and receive an RTB or IFM, and its

components, for your application.

Install the Module

You can install or remove the module while chassis power is applied.

Repeated electrical arcing causes excessive wear to contacts on both

the module and its mating connector. Worn contacts may create

electrical resistance that can affect module operation.

1. Align the circuit board with the top and bottom chassis guides.

2. Slide the module into the chassis until module tabs ‘click’.

WARNING When you insert or remove the module while backplane

power is on, an electrical arc can occur. This could cause

an explosion in hazardous location installations. Be sure

that power is removed or the area is nonhazardous before

proceeding.

Key the Module and Removable Terminal Block/Interface Module

Use the wedge-shaped keying tabs and U-shaped keying bands to

prevent connecting the wrong wires to your module.

Key positions on the module that correspond to unkeyed positions

on the RTB. For example, if you key the first position on the module,

leave the first position on the RTB unkeyed.

1. To key the module, insert the U-shaped band, as shown.

2. Push the band until it snaps in place.

3. To key the RTB or IFM, insert the wedge-shaped tab with

rounded edge first, as shown.

4. Push the tab until it stops.

Reposition the tabs to rekey future module applications.

Wire a Removable Terminal Block (RTB)

Your 1756-HYD02 module uses two types of RTBs (each RTB comes

with housing) to connect wiring.

·Cage clamp - Catalog number 1756-TBCH

·Spring clamp - Catalog number 1756-TBS6H

Connect the wires as shown below.

Spring Clamp RTB Cage Clamp RTB

20860-M

20859-M

1. Strip 7/16 inch (11mm) maximum

length of wire.

2. Insert the screwdriver into the

inner hole of the RTB.

3. Insert the wire into the

open terminal and

remove the screwdriver.

1. Strip 3/8 inch (9.5mm) maximum

length of wire.

2. Insert the wire into the open terminal.

3. Turn the screw clockwise to close the

terminal on the wire.

Wiring Registration Sensors

The registration inputs to the servo module can support 24V dc or

5V dc registration sensors. These inputs should be wired to receive

source current from the sensor. Current sinking sensor configurations

are not allowed because the registration input common (IN_ COM) is

shared with the other 24V dc servo module inputs.
