For mains connections and current connections, PSL recommends snap-on forked terminals, such as 3M Scotchlok
®
P/N MU18-
6FL or MU14-6FL, or Panduit P10-6lF. For other connections, PSL recommends wire ferrules for stranded wire, such as Panduit
F77 series, for example Panduit F77-6-M.
Figure 1: Your PQube meets all IEC requirements for high-
frequency emissions and susceptibility, both conducted and
radiated. For further protection, you can use clamp-on
ferrites on signal cables to minimize radio-frequency
emissions. For example, these are Panasonic
KRCBC160928B and KRCBC130714B.
Figure 2: To minimize emissions with the optional PS1
Power Supply module, optionally use a shielded power
conductor.

)
14 AWG (2.1mm

)
Min 600V UL-recognized insulation system required.
These terminals require less than 0,01 amps.
Connection to N (15) is optional. For single phase
monitoring, connect either L1-N or L1-L2 as
appropriate for the mains configuration.

)
Connect this terminal to a suitable earth connection.
For proper PQube operation, you must connect this
terminal to earth. It is used as a measurement
reference, and as a reference for your PQube’s low
voltage circuits.
Optional

Wire size must be adequate for relay contact load.
These terminals are rated at 30 VAC max, 60 Vdc
max, 2 amps max.

Ring lugs or snap-on forked terminals are
recommended for CT connections. Self-retaining
screws in terminals may make ring lugs challenging to
install. Wire size must be adequate for 1-amp or 5-
amp currents. Min 600V UL-recognized insulation
system required
