EXPLOSION HAZARD

 Substitution of components may impair suitability for

Class I, Division 2.

 Do not replace components or disconnect equipment

unless power has been switched off or the area is

known to be non-hazardous.

 Do not connect or disconnect components unless

power has been switched off or the area is known to be

non-hazardous.

 This product must be installed in an enclosure.

 All wiring must comply with N.E.C. article 501-4(b).

ATTENTION

Electrostatic discharge can damage integrated circuits or

semiconductors if you touch analog I/O module bus

connector pins or the terminal block on the input module.

Follow these guidelines when you handle the module:

 Touch a grounded object to discharge static potential.

 Wear an approved wrist-strap grounding device.

 Do not touch the bus connector or connector pins.

 Do not touch circuit components inside the module.

 Use a static-safe work station, if available.

 When it is not in use, keep the module in its

static-shield box.
