- Do not attempt to repair the Data Logger. If the Data Logger fails, please return the unit to your distributor for servicing.
Tampering with or opening the upper compartment of the Data Logger voids the product warranty.
- For pluggable equipment, the socket-outlet must be installed near the equipment and must be easily accessible.
- For Data Loggers equipped with a non-detachable power supply cord and a Polarized NEMA 1-15P plug, the plug is used
as the disconnect means.
- The Data Logger's internal circuits are provided with over-current fault protection on the line side only, not on neutral. For
protection against fire and to ensure proper power line communication (PLC) with the modules, a polarized plug must be
used. It is important to ensure that neutral is connected to the correct terminal of the plug and to the Neutral location on
the Data Logger's terminal block.
- The following labels are used on the Data Logger housing:
This label warns of hazardous voltages behind the AC terminal cover that can cause
serious injury or death if the cover is removed. This area is to be accessed only by
qualified, trained personnel with the necessary skills and knowledge to work on this
type of electrical equipment. Disconnect power before opening.
This label warns of immediate danger due to exposed hazardous voltages that can
