3.1.1 Locate the instrument within the reach of the cable provided for the DOE-601
3.1.2 Select an installation site which is:
• free of mechanical vibrations
• reasonably clean and dry
• protected from falling corrosive fluids within the ambient temperature and humidity
• remote from high voltage relay and power switches
3.2 Type of Mounting
3.2.1 If the instrument is to be pipe or panel mounted a special hardware kit will be
required. For panel mount order part number DOCN600-PM. For pipe mount order
part number DOCN600-PIPE. Instructions for both types of mounting will be
included with the kits.
3.2.2 For surface mounting, four feet brackets, together with fastening screws, are
provided with the instrument. These should be fastened to the back of the
instrument and then it may be screwed or bolted in the selected location.
3.3 Conduit Connections
3.3.1 Four 1/2" conduit holes are provided in the bottom of the enclosure. One of these is
fitted with an approved water tight plug. To maintain NEMA 4 integrity, approved
conduit hubs must be used to connect conduit. The hubs must be connected to the
conduit before being connected to the enclosure. Any unused conduit holes must
be closed with water tight plugs or connectors.
3.3.2 For convenience of internal connections the right conduit hole (viewed from the
front) should be used for power connection; the next hole to the left for relay
outputs; the next hole to the left for analog outputs and finally the fourth hole for
3.4 Electrical Connections
CAUTION: The instrument operates from line voltage. This constitutes a possible shock hazard.
Ensure that line power is removed before attempting connections. Note: A separate
source of line power may have been connected to the floating relay contacts.
3.4.1 To access the terminal strips open the door of the instrument and then unscrew the
captive retaining screw near the upper right hand corner of the panel. Now swing
open the panel to reveal the terminal strip on the power supply circuit board and the
smaller terminal strip on the back of the swing-out board.
