Power Quality Logger
Using the 1745 Power Quality Logger
17
• Use the Logger only with its original standard
equipment or with approved optional accessories as
listed in Table 2 and Table 3 in this manual.
• Connect clip-on current transformers and/or Flexi Set
to insulated live conductors only.
• If measuring sensors are to be connected to non-
insulated live conductiors, additional personal
protective measures must be taken as required by local
government agencies.
WCaution
To avoid damage, use the 1745 Power Quality Logger only
with the following nominal voltages:
Single/3-phase 4-wire (Wye) systems (P-N): 69 V to 480 V
3-phase-3-wire (Delta) systems (P-P): 120 V to 830 V
WX Warning
To avoid electrical shock, or damaging the Logger’s
internal protective circuitry or weatherproof seal, do not
open the Logger.
