Start Up

4.1.1 Inspection Prior to Start Up

Before applying power to the unit, inspect the entire installation as detailed in Table 4.1.

Inspect For	Description
	Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers that may reside on input
Auxiliary equipment	power side of drive or output side to motor. Examine their operational readiness and ensure they are ready in
	all respects for operation at full speed. Check function and installation of pressure sensors or encoders (etc.)
	used for feedback to drive. Remove power factor correction caps on motor, if present.
	Ensure that input power, motor wiring, and control wiring are in three separate metallic conduits for high
Cable routing	frequency noise isolation. Failure to isolate power, motor, and control wiring could result in less than optimum
	drive and associated equipment performance.
	Check for broken or damaged wires and connections. Check the voltage source of the signals, if necessary. The
Control wiring	use of shielded cable or twisted pair is recommended for serial communication. Ensure the shield is terminated
	correctly.
EMC considerations	Check for proper installation with regard to electromagnetic capability.
Environmental	See panel label for the maximum ambient operating temperature. Humidity levels must be less than 95% non-
conditions	condensing. Attitude less than 3300 feet.
Fusing and circuit	Check that all fuses are inserted firmly and in operational condition and that all circuit breakers are in the open
breakers	position.
	The panel requires a dedicated ground wire from its chassis to the building ground. It is required that the
Grounding	motor be grounded to the panel chassis. The use of conduit or mounting of the panel to a metal surface is not
	considered a suitable ground. Check for good ground connections that are tight and free of oxidation. Run
	insulated motor ground wire back to panel in conduit with motor wires.
Input and output	Check for loose connections. Check for proper fusing or circuit breakers.
power wiring
Panel interior	Panel interior must be free of dirt, metal chips, moisture, and corrosion. Check for harmful airborne contam-
	inates such as sulfur based compounds.
Proper Cooling	Panels require top and bottom clearance adequate to ensure proper air flow for cooling. See Figure 3.2 and
Clearance	Figure 3.3
Switches	Ensure that all switch and disconnect settings are in the proper position.
Vibration	Look for any unusual amount of vibration the equipment may be subjected to when mounting panel.

4.1.2 Start Up Procedure

In the following procedures, changing the equipment between drive mode and bypass mode is required. Changing modes is different for the ECB and EMB2. The ECB uses pushbuttons on the drive keypad while the EMB2 uses a selector switch on the front of the panel. Be familiar with the operation of these devices prior to start up.

WARNING

HAZARDOUS VOLTAGE!

The panel contains dangerous voltages when connected to line voltage. Installation, start-up and maintenance should be performed only by qualified personnel. Failure to perform installation, start-up and maintenance by qualified personnel only could result in death or serious injury.

1.Perform pre-startup procedure.

2.Ensure that all operator devices are in the OFF position. The main disconnect switch on the front of the electromechanical bypass panel must be in the OFF position. The panel door should be closed.

3.Keep main disconnect switch in the OFF position and apply voltage to the panel.

4.Confirm that input line voltage is balanced within 3%. If not, correct the input voltage imbalance before proceeding.
