IMPORTANT ENCODER INSTALLATION INFORMATION

Mounting the Encoder: The encoder should be mounted such that its shaft

is in close as possible alignment with the axis of the driving machine or

motor shaft.

CAUTION: The loads applied to the encoder shaft must be in

accordance with the specificatios of this device.

Important Wiring Instructions: Use of shielded cable is recommended for

all encoder installations. The shield should be connected to signal-ground

at the receiving device only.

Grounding: For applications with high ground potential differences,

DO NOT ground the encoder through both machine and controls end.

Connect the shield at the controls end only. NOTE: If the shield is

connected at both ends, grounding problems that degrade system

performance can result.

CE Grounding Measures – For best EMC immunity the cable screen

must be grounded on both encoder and controls end. For cable

lengths longer than 30m or outdoor applications, additional measures

must be implemented to comply with CE requirements. Connection of

the encoder to DC power supply network is prohibited if CE compli-

ance is required. CE-compliant products are tested to EN61326-1

EMC.

In all cases, system CE compliance is ultimately the responsibility of

the manufacturer integrating the encoder.

Connecting the shield at both ends can cause grounding problems

that degrade system performance.

If possible, run the encoder cable through a dedicated conduit (not shared

with other wiring). Use of conduit will protect the cable from physical

damage and provide a degree of electrical isolation. Do not run the cable

in close proximity to other conductors that carry current to heavy loads

such as motors, motor starters, contactors, solenoids, etc. This practice

can induce electrical transients in the encoder cable, potentially interfering

with reliable data transmission.

Refer to Electrical Connections table for wiring information. To avoid

possible damage, do not connect or disconnect the encoder connector or

wiring while power is applied to the system.

CAUTION: Unused encoder signal wires must be individually

insulated and under no circumstances be in contact with ground,

voltage sources, or other signal lines.
