5. Mounting the Controller
Mount the controller in a well ventilated, shaded area using the supplied mounting screws. The controller must
be mounted vertically. Be sure to leave 8 inches of free air space on every side of the unit. The controller must
be in an area with an ambient between 0º F and 122º F.
Note
Do not block the heat sink (fi ns) and do not set anything on the controller.
Warning
The controller access cover should always be securely fastened to the control box due

to the dangerous voltage/shock hazard inside the unit. A padlock tab on the bottom of

the enclosure can be used to further restrict access
6. Power Supply and Wiring
Power Supply
Note
Installation and maintenance MUST be performed by properly trained and qualifi ed personnel.
Always follow the National Electric Code or Canadian Electric Code, as well as all local, state
and provincial codes when wiring the system.
The controller requires a single-phase power supply of 196 – 264 VAC on a dedicated two-pole circuit
DANGER
breaker (not GFCI type). A dedicated circuit means no other appliances use the same circuit! The
Hazardous
voltage
output power from the controller is three-phase, variable frequency and variable voltage. Maximum
output voltage and frequency are line input voltage and 60 Hz, respectively. Motor must be 3 phase and
designed for the same voltage as supplied to the controller. For example, if the controller is supplied with
200 V, then the motor should be rated for 200 V. Low supply voltage will reduce pump performance. Refer
to table 1 for Circuit Breaker & Wire Sizing.

Wire and Conduit
Factory installed input and output power leads may be supplied with the controller. Use 75º C or higher rated
UL type copper wire. Use of Metal Conduit with Metal Conduit liquid tight Connectors is recommended for all
electrical connections.
