Connecting Voltage Measurement Cables
Measurement cable set
Description: Voltage measurement cables are provided as standard accessories and are
stored in a cable pouch as part of the measurement cable set, P/N 116042-G3. Each
cable set consists of a cable and alligator clip.
Voltage Rating: Direct connection of all voltage measurement cables are rated at 600
Vrms max. For measuring voltages greater than 600 Vrms, potential transformers (PTs)
must be used.
Optional fused voltage adapter
There are two optional fuse accessory kits available for use with the measurement
cables for PX5. One kit (P/N FVA-1) contains one fused voltage adapter and one
measurement connecting Red cable 50 cm in length. The other kit (P/N FVA-4) contains
four voltage adapters and four measurement connecting cables 50 cm in length (one
Red, one Yellow, one Blue, and one Grey).

WARNING:
To avoid the risk of electric shock or burns, always connect the safety (or
earth) ground before making any other connections.
•
WARNING
: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Fuses must be located as close
to the load as possible to maximize protection.
•
WARNING
: For continued protection against risk of fire or shock hazard replace only
with same type and rating of recommended fuse. Use only fast blow type fuse which is
rated 600V. Recommended fuse type is Littelfuse, part number KLKD0.30 rated 600V
AC/DC, 0.3A fast blow.
•
WARNING
: Do not replace fuse again if failure is repeated. Repeated failure indicates a
defective condition that will not clear with replacement of the fuse. Refer condition to a
qualified technician.
