The Model 450H NEMA 4X is shipped with the following standard equipment: 1. Instruction manual.
CAUTION
To avoid personal injury, always use two persons to lift and
carry the Model 450H.
Upon receiving the Model 450H please do the following:
2.Verify no apparent shipping damage. (If damage has occurred please advise shipper first, then Teledyne API.)
3.Mount the 450H to a vertical surface using four 5/16” bolts. See Figure 1.1 for mounting hole dimensions.
4.PVC piping of ½” or the metric equivalent must be placed on the bulkhead conduits.
If a bulkhead conduit is not used it must be plugged to assure the watertight seal on the unit. If this is not done the protection rating of the unit will be greatly compromised
If the fittings are not the correct type for your application consult an electrician to wire the unit according to the local electrical code.
5.Before connecting power to the instrument, check the serial number tag to verify that the instrument has been configured for the correct line voltage and frequency. The AC power line should be routed through one of the three ½” conduit bulkheads on the bottom face of the enclosure. A barrier strip inside the inside the enclosure is provided for wiring the AC line to the instrument. See Figure 1.2 for details on these connections.
CAUTION
Verify that the instrument is set up for proper line voltage and
frequency.
6.Connect an exhaust line to the fitting labeled ‘Exhaust.’ If the M450H has been configured with the ozone killer option, this line should be vented to an outside area, since the exhaust gas may still contain trace levels of ozone. If the M450H has not been equipped with an ozone killer, this line should be vented to an ozone destruct unit or other appropriate device.
