NOTICE

Risk of damage to internal components!

Do not engage or disengage any connecting elements

while the product is under power.

Depending on the product's equipment, the

installation may differ from the procedure

described in this chapter. If the Addendum

included with the product contains information

on the installation, the information given in

the Addendum takes precedence over the

information in this chapter.

The safety of any system incorporating the

use of this product is the responsibility of the

assembler or installer of the system.

The illustrations of pin layouts always show the

pin assignments of the connectors, and not of

the connections on the product.

Personnel requirement

Connecting power

WARNING

Risk of electric shock!

Improper grounding of electrical devices involves a risk of

serious injury or death by electric shock.

Always use 3-wire power cables.

Make sure the ground wire is correctly connected to

the ground of the building's electrical installations.

WARNING

Fire hazard from the use of power cables that do not

meet the minimum requirements!

Use only power cables that fulfill or exceed the

specified minimum requirements.

NOTICE

Surge suppressors limit the amplitude of potentially

damaging power line transients caused by electrical

machinery or lightning, and protect the product from

most power line transients that can corrupt system

memory or damage circuits.

Always connect the unit to power through a high-

quality surge suppressor.

Use the supplied power cable to connect the power

connector to a 3-wire grounded power outlet. For

information about the location of the power connector

on the rear panel, see "Rear panel", page 17.

Electrostatic discharge

NOTICE

This product contains components

that can be destroyed by electro-

static discharge (ESD).

It is essential to observe the safety

precautions for handling ESD-sensiti-

ve components.

Never touch connector pins without

ensuring proper grounding.

4.4

Connecting measuring devices

Connection possibilities

Measuring devices are connected to the channel inputs

provided on the rear panel. For information about their

location on the rear panel, see "Rear panel", page 17.

The number and type of connectors available for the

measuring devices may vary from unit to unit.

Connecting the measuring device cables

Connect the cables of the measuring devices tightly to

the respective connectors on the rear panel.

If the connectors include mounting screws, do not

overtighten them.

Vacant pins or wires must not be used.

Connecting a computer

Connect a computer COM port to the unit's RS-232/V.24

serial port using a standard serial cable. For information

about the port's location on the rear panel, see "Product

overview", page 17.

Make sure the cable is securely attached. Do not

overtighten the connector screws.

For information on the configuration of the

RS-232 port, e.g. for products with a second

RS-232/V.24 serial port for the connection

of RS-232/V.24 measuring systems, see the

Operating Instructions.

4.6

Connecting headphones and USB printer

Connecting headphones

Audio alerts can be sent to headphones in areas that are

noisy and make it difficult to hear, or are quiet where audio

alerts might create a disturbance.

For more information about the audio output, see

"Specifications", page 20.

Plug the headphones into the audio jack on the side of

the unit. Make sure the headphone plug is fully inserted.

For information on the location of the headphone jack,

see "Rear panel", page 17.

Headphone plug: Pin layout

See "K" in the Appendix.

Connecting a USB printer

The unit supports certain USB printers.

A list of supported printers is available as a

document from 

www.heidenhain.de

.

Connect the USB printer to the USB Type A port on the

side of the housing. Make sure the USB cable plug is

fully inserted. For information on the location of the USB

port, see "Rear panel", page 17.

4.7

Connecting a foot switch and remote

keypad (optional accessories)

See "D" in the Appendix.

The foot switch and the remote keypad are

available as optional accessories. For more

information see "Items supplied", page 16.

Connecting the foot switch

The connecting cable fixed to the foot switch has an RJ-45

plug for connection to the RJ-45 jack on the left side of the

unit.

Connect the RJ-45 plug of the foot switch to the RJ-45

jack provided on the unit.

Connect the remote keypad

The remote keypad is connected to the RJ-45 jack on the

left side of the unit by using a cable with RJ-45 plugs on

both ends.

Plug a cable with RJ-45 plugs into the RJ-45 jacks on the

unit and on the remote keypad.

Connecting foot switch and remote keypad

simultaneously

The foot switch and the remote keypad can be

used individually or in combination.

The foot switch and the remote keypad can be

connected simultaneously using an RJ-45 splitter

that is plugged into the RJ-45 jack on the left

side of the unit. RJ-45 splitters are available from

most retail electronics stores.

RJ-45 plug: Pin layout

See "M" in the Appendix.

Wiring of switching inputs and outputs

The functions are based on the formulas and

values stored by qualified personnel.

The wiring of the switching inputs and outputs depends

on the customer's peripherals (see manufacturer's

documentation).

Personnel requirement

Depending on the peripherals to be connected,

the connection work may need to be carried out

by an electrical specialist.

Example: SELV exceeded.

Relay connection

The contacts of a single-pole, double-throw dry-contact

relay are accessible on the product's rear panel for special

applications requiring low-power electrical switching. The

normally open and normally closed contacts of the relay are

available for use in low-current, low-voltage applications.

For more information on the relay connection, see

"Specifications", page 20.

Relay connector:

Pin layout

See "N" in the Appendix.

Data I/O connection

The I/O interface enables the digital readout unit to

communicate with the peripherals through TTL inputs and

outputs. Signals from peripherals can be evaluated and

connected peripheral devices can be controlled.

For more information about the I/O connection, see

"Specifications", page 20.
