SVP48 Surge Voltage Protector

top nut on the ground chuck and place the ring end of the ground wire on the
chuck. Replace the top nut. Insert the tinned end into the open yellow/green
clamp terminal, then tighten the terminal. Ground the enclosure to earth with
14 AWG or larger wire.
2.3 Attaching Sensors to the SVP48
To provide complete protection for the datalogger, all leads must pass through
the SVP48. All shield wires terminate in one or more of the yellow/green
clamp terminals.
To connect signal or excitation leads, insert the bare end of one lead into the
terminal on either side of the surge protector. Run a short length of wire from
the other side to the appropriate datalogger terminal. This short length of wire
should be of the same gage and insulation type as the sensor leads provided by
the manufacturer. Do not use wire with PVC insulation.
3. Maintenance
3.1 Replacement Considerations
When an electrical surge occurs, the surge protectors involved may need to be
replaced. Incorrect measurements will indicate that replacement is necessary.
With an ohmmeter, confirm that an individual protector needs replacing by
measuring the resistance between a top terminal and the yellow/green terminal.
An open circuit or infinite resistance indicates that the surge protector is okay.
Any other resistance reading indicates that it needs replacing.
