Mounting Your External Shunt
Resistor
To mount your 1394-SR10A Shunt Resistor:
1. Remove all 24V control power, contactor enable power, and 360/
480V AC input power from the system.
2. Wait at least two minutes for the DC Link to discharge.
!
ATTENTION: These resistors can reach temperatures
in excess of 350
°
C (662
°
F). Appropriate guarding must
be provided to avoid the hazard of shock or burn and
ignition of flammable material. Install per local codes.
