Remove the Instrument from its packing. A panel gasket and a “no tools required” fixing strap are supplied. Retain the packing for future use (e.g. moving the Instrument to a different site). 2. Examine the delivered items for damage or deficiencies. If any are found, notify the carrier immediately. Check that the Product Code on the label affixed to the Instrument housing corresponds to that ordered. 49mm B.B.B.B. 25mm 10 mm approximately FIGURE 1-1 Main Dimensions 14 INSTALUNQ THE INSTRUMENT IN THE MOUNTING PANEL CAUTION: Do not remove the front panel gasket from the Instrument, as this may cause inadequate clamping of the Instrument to the mounting panel. Ensure that this gasket is not distorted and that the Instrument is positioned squarely against the mounting panel. Apply pressure to the front panel bezel only.

The power consumption is approximately 4W. CAUTION: This equipment is designed for installation in an enclosure which provides adequate protection against electric shock. Local regulations regarding electrical installation should be rigidly observed. Consideration should be given to prevention of access to the power terminations by unauthorized personnel. Power should be connected via a two-pole isolating switch (preferably situated near the Instrument) and a 1A fuse, as shown in Figure 2-2. FIGURE 2*2 Mains (Line) Supply Connections If the contacts of the relay output(s) are used to carry mains (line) voltage, it is recommended that the relay contacts mains (line) supply should be switched and fused in a similar manner but should be separate from the Instrument mains (line) supply. Z2 LOW VOLTAGE (24V AG/DC) SUPPLY - OPTION This version of the Instrument will operate on 12 - 24V AC 50/60Hz or 12 -30V DC supply. The power consumption is approximately 4W. The connections are shown in Figure 2-3; these should be made via a two-pole isolating switch and a 315mA slow-blow (anti-surge Type T) fuse.
