Connecting Voltage Measurement Cables
Description: Voltage measurement cables or customer-supplied wiring are used as
Measurement
cable set
connectors for Voltage input modules with safety jack or terminal block connectors,
respectively.
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. Any customer-supplied wiring should be UL-listed for 600 Vrms
minimum for inputs rated 600 Vrms max and 1000 V minimum for inputs rated 1000 V
max.
Description: A voltage measurement cable set, P/N 116042-G1, is available as an
Optional cable
set for 61MVB
optional accessory to be used with the 61MVB Voltage Module.
Contents: The voltage measurement cables are shown on page 2-22. A cable set
consists of eight, 6-foot channel measurement cable assemblies (probes), each with a
detachable, alligator jaw, safety clip assembly (maximum jaw opening, 3/4 in (20
mm)). The safety clip assemblies are red (+) and black (-) for each of the four channels.
One cable each of red (channel A), yellow (channel B), blue (channel C), and grey
(channel D), and four each of white are provided.
A pouch for storage of the cables is included in the contents of the measurement cable
set, but is not shown in the figure.
There are two optional fuse accessory kits available for use with the measurement
Optional fused
voltage adapter
cables. 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).
The single fuse voltage adapter kit is used for one single voltage measurement input.
While the four fuse voltage adapter kit is used for a three phase and neutral voltage
measurement inputs. If these fuse kits are not used, it is recommended that the user use
terminal strips to fused circuits, preferably with local disconnects.
