Based on no more than three single insulated conductors rated 0-2000 volts. 6. If fuse is not a standard size, choose the next higher standard size.2. Conduit sizes shown at 9.6% Fill does include ground conductor if required (over 60 amperes). 7. If disconnect is not a standard size, choose the next higher standard size.3. Wire sizes are based on NEC Table 310.15.b.16 @ 75 deg. C rated conductors.4. Approved trade size conduit or metal tubing.5. Above information is general information. Per NEC tables please confirm motor FLA does not exceed FLCNote: Fuse and disconnect sizes are for vacuum pump only. For main disconnect and fuse sizes for systemswith a circulation pump and fan, multiply the FLC of the vacuum pump motor by 175% then add the FLC forthe circulation pump and fan to get the fuse size. Disconnect must be sized to fit fuse.All system wiring is performed at the factory if a control panel is supplied. Check area classification to ensureall electrical enclosures comply with code. Required customer wiring is minimal, but should be done by aqualified electrician in compliance with OSHA, National Electric Code and any other applicable local electricalcode concerning switches, fused disconnects, etc. DEKKER includes a wiring diagram in the control panel foruse by the installer. DEKKER recommends a main disconnect switch be fitted between the vacuum system andthe incoming power.After the electrical wiring connections are completed check the incoming voltage to make sure the incomingvoltage is the same as the vacuum system voltage. Line voltage should be within the voltage tolerance asspecified on the motor or to local code. Check the system for proper motor rotation. The direction ofrotation is always clockwise when looking at the shaft of the pump and is marked by an arrow on the motor orpump housing. Jog the motor by pressing the ON button and then the OFF button. If the rotation is incorrectswitch any two of the three main power leads on the contactor inside the control panel. Failure to do so couldresult in serious equipment damage. |
