SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
•TURN THE INPUT POWER OFF AT THE DISCONNECT SWITCH BEFORE ATTEMPTING TO CONNECT OR DIS-
CONNECT INPUT POWER LINES, OUTPUT CABLES, OR CONTROL CABLES.
•Only qualified personnel should perform this installation.
•Connect the green/yellow lead of the power cord to ground per appropriate National Electrical Code.
SELECT SUITABLE LOCATION
The Invertec
•The machine must be located where there is free cir- culation of clean air such that air movement in the back, out the sides and bottom will not be restricted.
•Dirt and dust that can be drawn into the machine should be kept to a minimum. Failure to observe these precautions can result in excessive operating temperatures and nuisance shutdown.
•Keep machine dry. Shelter from rain and snow. Do not place on wet ground or in puddles.
STACKING
TILTING
Place the machine directly on a secure, level surface or on a recommended undercarriage. The machine may topple over if this procedure is not followed.
INPUT AND GROUNDING CONNECTIONS
•Only a qualified electrician should connect the Invertec
•When received directly from the factory, multiple voltage machines are internally connected for 440VAC. If 440VAC is the desired input, then the machine may be connected to the power system without any setup required inside the machine.
•Initial 200VAC - 415VAC operation will require an Input voltage panel setup.
•Open the access panel on the rear of the machine.
•For 200 or 230: Position the large switch to
For higher voltages: Position the large switch to ≥ 380.
•Move the "A" lead to the appropriate terminal.
