Preface 2

Safety Precautions

The following general precautions apply to the ALEC:

ATTENTION

Electric shock can kill. Make sure the ALEC is safely

installed in accordance with the Installation and

Set-up chapters of this manual. Avoid contact with

electrical wires and cabling while power is on. Only

trained service personnel should open the electrical

cabinet.

This product contains stored energy devices. To

avoid hazard of electrical shock, verify that all

voltage on the capacitors has been discharged before

attempting to service, repair, or remove this unit. You

should only attempt the procedures in this manual if

you are qualified to do so and familiar with

solid-state control equipment and the safety

procedures in publication NFPA 70E and BS-EN

60204.

The system integrator is responsible for local safety

and electrical codes.

ATTENTION

An incorrectly applied or installed product can result

in component damage or a reduction in product life.

Wiring or application errors, such as undersizing or

inadequate DC supply, or excessive ambient

temperatures can result in a malfunction.

The ALEC contains ESD (Electrostatic Discharge)

sensitive parts and assemblies. Static control

precautions are required when installing, testing,

servicing, or repairing this assembly. Component

damage can result if ESD control procedures are not

followed. If you are not familiar with static control

procedures, refer to Allen-Bradley publication

8000-4.5.2, Guarding Against Electrostatic Damage or

any other applicable ESD Protection Handbook.
