STARTING THE SYSTEM
Section 7
(continued)
DANGER
The controller has high leakage current to ground. The output terminals marked "GND" or
DANGER
" " must be directly connected to the motor ground. Failure to properly ground the controller
Hazardous
voltage
or motor will create an electrical shock hazard.
Input Power Connections
Make sure disconnect switches or circuit breakers are securely in the OFF position before making
DANGER
this connection. Run the input power wires from the fused disconnect through metal conduit to
Hazardous
voltage the bottom of the controller. Use metal conduit and metal conduit connectors. Size the conduits
according to the NEC, CEC or local codes. Use the wire sizing chart in the appendix to determine
the size of the input power wires. Connect the conduit and insert the wires into the far left opening on the
controller. Connect wires to the "INPUT" terminal block. Connect the ground wire to the terminal labeled GND.
For three phase input, connect the input phase wires to L1, L2 and L3. For single phase input, connect the input
wires to L1 and L3. If single phase input is used the motor overload switches must be set to 50% or lower.
CAUTION
The wire used for input power connections on models SPD20300 and SPD20300F must have a temperature
rating of 90ºC minimum.
DANGER
The controller has a high leakage current to ground. The input terminals marked "GND" must be
DANGER
directly connected to the service entrance ground. Failure to properly ground the controller or
Hazardous
voltage
motor will create an electrical shock hazard.
NOTE
If single phase input power is used the Motor Overload switches must be set to 50% or lower or nuisance
input phase loss errors can result.
NOTE
Do not use GFCI protection with this controller. Nuisance tripping will result.
DANGER
Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch and
DANGER
circuit breaker and wait 5 minutes before servicing.

voltage
DANGER
The controller will remain electrically charged for 5 minutes after power is turned off. Wait 5
DANGER
minutes after disconnecting power before opening controller access cover as there is a severe
Hazardous
voltage
shock hazard.
