User Manual 3155

2-4 Installation

Removing the In-

strument from the

Bag

The 3155 is supplied in an antistatic bag. Check the seal on the bag

to make sure the bag was not opened in a static unsafe environment.

Place the enveloped card on static free surface and hook yourself up

with a grounding strap. Only then break the seal and remove the card

from the envelope. Hold the card at the metal panel end. Refrain

from touching the instrument with your finger at all times.

Installation

The instrument is fully solid state and dissipates only a small amount

of power. No special cooling is required. However, the instrument

should not be operated where the ambient temperature exceeds

50°C, when the relative humidity exceeds 80% or condensation ap-

pears anywhere on the instrument.

Avoid installation of the instrument close to strong magnetic fields,

which may be found near high power equipment such as motors,

pumps, solenoids or high power cables. Use care when rack mount-

ing the PXI chassis to locate it away from sources of excessive heat

or magnetic fields. Always leave 5 cm (2 inches) of ventilation space

on all sides of the chassis.

Plug the 3155 into your PXI chassis and lift the extractor to the up-

right position. Push the card firmly until the metal panel makes con-

tact with the metal edge of the PXI chassis. Using a suitable screw-

driver, tighten the two retaining screws, top and bottom.

WARNING

Inserting and removing the 3155 should be done with the

power cord removed from the PXI chassis or with the

PXI chassis in stand-by mode. An attempt to insert or

remove the instrument while power is supplied to the

PXI backplane will result in severe damage to the in-

strument and will void warranty.
