Physical
Terminal block with 10-32 Studs for current inputs. Use ring lugs sized for #10 stud.
Accepts #10-16 AWG (5.3-1.3mm
Current inputs are connected to the output from the secondary of permanently installed
Current Transformers (CTs). Grounding of CT signals per ANSI/IEEE C57.13.3-1983 is
required.
Terminal block with 8-32 Screws for current inputs. Use ring lugs sized for #10 screw thread.
Accepts #10-22 AWG (5.3-0.33mm
Current inputs are connected to the output from the secondary of permanently installed
Current Transformers (CTs). Grounding of CT signals per ANSI/IEEE C57.13.3-1983 is
required.
2 position removable terminal block, accepts 26-14AWG stranded wire. Recommended
Torque 7 in-lbs, 0.79N-m.
To maintain the safety features of this product, a 3 Ampere time delay (T) fuse must be
connected in series with the ungrounded/non-earthed (hot) side of the supply input connected
to the voltage measurement (VT) input of the instrument prior to installation. The fuse must
carry a voltage rating appropriate for the power system on which it is to be used. A 3 Ampere
slow blow UL Listed fuse in an appropriate fuse holder should be used in order to maintain
any UL product approval.
Removable Terminal Block, accepts #22-12 AWG (0.35 to 3.3mm
to 0.250" (6.35mm) wide. Standard 0.200" (5.08mm) header socket accepts other standard
terminal types. Precautions must be taken to prevent shorting of lugs at the terminal block.
A minimum distance of 1/8" (3mm) is recommended between uninsulated lugs to maintain
insulation requirements. Recommended Torque: 10 In-Lbs, 1.13 N-m
