Mechanical installation
See chapter ‘Introduction – Technical data’ for references to PM, DT and HE
mechanical measures: outer extents, body extents and panel cutout (PM).
PM type instrument:
Make sure the panel thickness meets the specification and that there is room enough
behind the panel for the instrument and the connected cables (minimum 200 mm).
Cut a panel opening according to the specification on page 1-5.
Insert the instrument through the opening. Hold it in place while attaching brackets
and wing-headed bolts to the four nuts, sliding in grooves of the housing.
Tighten the bolts and make sure the integrated gasket of the instrument is
compressed against the mounting panel, giving a sealed attachment.
DT and HE type instrument:
Arrange enough space for cables and strain reliefs behind or below the instrument.
DT instrument housings have 6 plugged openings facing downwards, intended for
the cable strain reliefs. As an alternative, knock-out openings in the back panel can be
knocked open for strain reliefs facing backwards.
HE instrument housings have 12 plugged openings for the cable strain reliefs, facing
downwards and backwards.
Enclosed with each instrument is a set of 6 strain reliefs. For each cable one strain
relief should be mounted with a sealing washer on the exterior and a locknut inside
the housing.
Mounting legs are fitted to the instrument housings by knob-headed bolts and threaded
holes or nuts. Use the enclosed fixing brackets to attach the legs to the table or a wall.
