Protective Fuses

The 9700 Power Meter is internally protected on the L/+ or + terminal by a
3A IEC Type T slow-blow fuse. If the power is supplied from a grounded
source, installation of a 3A slow-blow fuse on the L/+ or + terminal is
recommended. If power is supplied from an ungrounded source,
installation of 3A slow-blow fuses on both L/+ or + and N/- or – terminals is
recommended.

Connecting the MGT

The MGT is connected to the 9700 Power Meter by the supplied DB9 cable.
The cable connects to the single connector on the rear panel of the MGT,
and to the MGT connector on the 9700 Power Meter. Hand-tighten the
securing screws on each cable connector. Refer to the 9700 Power Meter
Operation Manual for MGT configuration details.

Connecting the Phase Voltage Inputs

AWG 12 to 14 wire (2.5 to 4.0 mm

2

) is recommended for all phase voltage

connections. Phasing and polarity of the AC voltage inputs and their
relationship is critical to the correct operation of the unit. All phase voltage
sense leads should be protected by breakers or fuses at their source.

Voltage Input Specifications

Voltage input ranges are defined by ordering options (see “Direct
Connection”). Voltage input overload withstand rating is 1500 VAC RMS
continuous and 2500 VAC RMS for one second, non-recurring. Input
impedance is 2 M

Ω

.

Direct Connection

Whether or not potential transformers (PTs) are required depends on the
nature of the system being monitored, the voltage levels to be monitored,
and the phase voltage input option of the 9700 Power Meter. The 9700
Power Meter can be directly connected to voltage levels shown in the table
below (no PTs are required).

120 VAC L-N, 208 VAC L-L

277 VAC L-N, 480 VAC L-L

347 VAC L-N, 600 VAC L-L

Refer to the 9700 Power
Meter’s label for the voltage
input option purchased.

-

14368%28

Ensure that the voltage level
between each phase input (V1,
V2 or V3) and the V

REF

input

does not exceed the input
range:

•120 volts for the –120 option
•277 volts for the –277 option
•347 volts for the –347 option
