1. Cut an opening in the panel to accommodate the bracket frame provided.
2. Install the provided frame in the opening.
3. Fold the 6 tabs over the panel lips, using adjustable joint pliers.
4. Slide the instrument in the bracket frame. The instrument should go over the four "T" pins. Rotate the 4 fast
locking screws on both sides of the front panel and slide it in.
5. Rotate the 4 fast locking screws 1/4 turn twice in the lock direction as indicated on the side of the front panel.
This locks the instrument in place on the four "T" pins.
6. To access the connections inside the instrument, remove the instrument housing (six screws on the back
panel, and slide the housing back out)
7. Pass the cables through the housing, then through the cable gland (if applicable) and then perform the
connections as detailed below.

Potential Electrocution Hazard. In order to maintain the NEMA/IP environmental ratings of the enclosure, use only
conduit fittings and cable glands rated for at least NEMA 4X/IP65 to route cables into the instrument.
Cable gland wiring instructions
A waterproof cable gland is provided each time a cable must be connected inside the instrument.
The nickel-plated brass cable glands are EMC-types, designed so that the cable shields attach
directly to the instrument housing as a ground. Typical cable wiring instructions are detailed below.
1. Unscrew the cable gland nut. Inside, the assembly is composed of a rubber gasket, and two
metal washers. Note that the ethernet gland on panel and wall mount instruments does not have
washers and the gasket is cut.
2. If wiring a sensor cable, the cable has already been prepared so simply remove the piece of
plastic protection from the exposed shielding. For other cables, strip off external insulation as
required, and 25 mm of shielding. Strip the wires about 8 mm from their ends.
3. Pass the cable through the nut, the rubber gasket, and the two washers.
