Connections
All connections are made to removable screw
terminal connectors located at the rear of the meter.
Use copper wire with 60°C or 60/75°C insulation
for all line voltage connections. Observe all safety
regulations. Electrical wiring should be performed
in accordance with all applicable national, state,
and local codes to prevent damage to the meter
and ensure personnel safety.
Connector Labeling
The connectors label, affixed to the meter, shows the
location of the connectors available with requested
configuration.

(Optional)
The current input is protected against current
overload by a resettable fuse. The display may or
may not show a fault condition depending on the
nature of the overload.
The fuse limits the current to a safe level when it
detects a fault condition, and automatically resets
itself when the fault condition is removed.
Figure 9. Voltage Input Connections
The meter is capable of accepting any voltage from
-10 VDC to +10 VDC.
