sides of the bezel.

2. The bezel along with
the board assembly
will unlatch from the
case housing.

WIRING

Wire the instrument according to the figure shown below.

Warning: Do not connect ac power to your device
until you have completed all input and output
connections. This device must only be installed by
a specially trained electrician with corresponding
qualifications. Failure to follow all instructions and
warnings may result in injury!

This Quick Start Reference provides information
on setting up your instrument for basic operation.
The latest complete Communication and Operational
Manual as well as free Software and ActiveX Controls
are available at www.newportUS.com/i or on the

CD-ROM enclosed with your shipment.

SAFETY CONSIDERATION

This device is marked with the international
Caution symbol.

The instrument is a panel mount device protected in
accordance with EN 61010-1:2001, electrical safety
requirements for electrical equipment for measurement, control
and laboratory. Remember that the unit has no power-on
switch. Building installation should include a switch or circuit­breaker that must be compliant to IEC 947-1 and 947-3.

SAFETY:

• Do not exceed voltage rating on the label located on
the top of the instrument housing.

• Always disconnect power before changing signal and
power connections.

• Do not use this instrument on a work bench without
its case for safety reasons.

• Do not operate this instrument in flammable or
explosive atmospheres.

• Do not expose this instrument to rain or moisture.

EMC:

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wire close to the
instrument if EMC problems persist.

MOUNTING

Panel Mounting Instruction:

1. Using the dimensions from the panel cutout diagram

shown above, cut an opening in the panel.

2. Remove sleeve from the rear of the case by removing
thumbnuts.

3. Insert the unit into the opening from the front of the panel, so
the gasket seals between the bezel and the front of the panel.

4. Slip the sleeve over the rear of the case.

5. Tighten the thumbnuts to hold the unit firmly in the panel.
