INSTALLATION AND WIRING

INSTALLATION

The Model 951 enclosure is designated for panel mounting in a 1/8 DIN cutout. The cutout dimensions are shown below.

1.772" 45mm

(+0.024, -0.000)

92 mm

3.622" (+0.032, -0.000)

To panel mount the 951, perform the following steps:

1.Rotate the four pawl screws ( outside screws in each corner) several turns counter-clockwise to retract the pawls. Make sure the pawls retract enough to clear the back of the mounting panel. The pawls may be retracted to accomodate panel thicknesses up to 0.25 inches (6.35mm).

2.Insert the instrument into the panel cutout.

3.Position the pawls so that their elongated dimension overlaps the panel cutout, then tighten the screws. Do not over-tighten.

4.Installation complete.

WIRING

Reference Figures 3 and 4 for TRANSDUCER and INPUT/OUTPUT (I/O) wiring information. Power is applied with a 3-prong AC power cord (Europlug). The instrument is protected by a 250V, 500ma, slo blo, 5mm fuse. The fuse holder is an integral part of the input power connector.

A spare fuse is provided in the fuse holder. Internal solder jumpers are provided to allow 100, 110 or 240VAC operation.
