5 Electrical Installation
Warning.
To comply with Underwriter Laboratories (UL) and Canadian Standards Association (CSA) certification, route signal leads
and power cables in earthed (grounded), flexible metal conduit.
Recorders not fitted with the optional internal on/off switch and fuse must have an external fuse and disconnecting device
such as a switch or circuit breaker conforming to local safety standards fitted to the final installation. They must be fitted in
close proximity to the recorder within easy reach of the operator and must be marked clearly as the disconnection device
for the recorder.
Remove all power from supply, relay and any powered control circuits and high common mode voltages before accessing
or making any connections.
Use cable appropriate for the load currents. The terminals accept cables up to 14AWG (2.5mm2).
The power supply and all inputs and outputs conform to Insulation Category II, Pollution Degree II.
All connections to secondary circuits must have basic insulation.
After installation, there must be no access to live parts e.g. terminals.
Terminals for external circuits are for use only with equipment with no accessible live parts.
If the recorder is used in a manner not specified by the Company, the protection provided by the equipment may be
impaired.
All equipment connected to the recorder's terminals must comply with local safety standards (IEC 60950, EN601010-1).
Note.
Always route signal leads and power cables separately.
Use screened cable for signal inputs and relay connections. Connect the screen to the earth (ground) stud – see Fig. 5.9 on
page 71.
The terminal blocks can be removed from the main PCB when making connections – see Fig. 5.1 on page 65. Before
removing a module, note its position.
If wall- or pipe-mounting to NEMA 4X hosedown standard is required, suitable cable glands
must
be used to prevent water
ingress.
The optional Software Key (if fitted), part number C1900/0463, contains a non-replaceable 3.0V lithium cell.
