5.3 Input Power Connections
Risk of electric shock – cord connected models are supplied with a grounding
conductor and grounding-type attachment plug. To reduce risk of electric shock, be
certain that it is connected only to a properly grounded, grounding-type receptacle.
WARNING
!
Be certain to connect pump to proper supply voltage. Using incorrect voltage will damage
pump and may result in injury. Voltage requirement is printed on pump serial label.
!
Input power range is 96VAC to 264VAC 50/60 Hz.
!
Voltage Selection is automatically detected and adjusted by power supply. No mechanical
switch necessary.
!
Use voltage your power cord is rated for.
!
Power cord models are supplied with a ground wire conductor and a grounding type attach-
ment plug (power cord). To reduce risk of electric shock, be certain that power cord is con-
nected only to a properly grounded, grounding type receptacle.
!
Be sure all M12 wiring cable glands are properly installed and sealed.
!
Never strap control (input / output) cables and power cables together.
!
Power Interruption: This pump has a user programmable auto-restart feature which will can
either restore the pump to the operating state it was in when power was lost or require a user
action to restart.
Note: When in doubt regarding your electrical installation, contact a licensed electrician.
Electrical connections and grounding (earthing) must conform to local wiring codes.
WARNING
Risk of electric shock - Disconnect electricity before removing the wiring
compartment cover.
