• Installation
Caution: In order to meet product safety requirements, these units must
only be installed, by qualified staff, in accordance with the information
given in this manual, and all relevant national electrical wiring and
safety rules must be followed.
Industrial signals are frequently floating with respect to local earth,
so take care while connecting the signal wires. The LPD450F is not
intended to be connected to signals floating above 00 Vrms with
respect to local earth.
Location and mounting
Locate the instrument in an area that is free from dust, moisture and
corrosive gases.
The standard mounting method uses four 4 mm screws through
the housing. Mounting hole spacings are 10 x 60 mm. Remove the
front cover to gain access to the holes. Note: do not drill holes in the
enclosure as this will compromise the IP67 rating.
The optional pipe mount bracket can be attached to suit fitting to a
50 mm pipe. See below for assembly.
Access to instrument terminals
1. Remove the transparent front cover.
. Release the thumbscrews from the either side of the LCD display.
. Lift the electronics from the housing using the thumbscrews.
The connections for the instrument are on the underside of the
electronics and are marked for polarity. Use a suitable crimp lug for
connections.
