Safety
WARNING
EQUIPMENT HAZARD!
The vertical bypass/non bypass panel contains dangerous voltages when connected to mains voltage. It is strongly recommended that all electrical work conform to the National Electrical Code (NEC) and all national and local regulations. Installation, start-up and maintenance should be performed only by qualified personnel. Failure to follow the NEC or local regulations could result in death or serious injury.
Motor control equipment and electronic controls are connected to hazardous mains voltages. Extreme care should be taken to protect against shock. The user must be protected against supply voltage and the motor must be protected against overload in accordance with applicable national and local regulations. Be sure equipment is properly grounded. Wear safety glasses whenever working on electric control or rotating equipment.
WARNING
UNINTENDED START!
When the vertical bypass/non bypass panel is connected to AC input power, the motor may start at any time. The drive, panel, motor, and any driven equipment must be in operational readiness. Failure to be in operational readiness when panel and drive are connected to AC input power could result in death, serious injury, or equipment or property damage.
Warning against unintended start
When the vertical bypass/non bypass panel is connected to mains, the motor may be started by means of an external switch, a serial bus command, an input reference signal, or a cleared fault condition. Use appropriate cautions to guard against an unintended start.
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground drive, vertical bypass panel, and motor properly. Follow the grounding guidelines of local and national codes. Failure to follow grounding guidelines could result in death or serious injury.
Grounding
Correct protective grounding of the equipment must be established in accordance with national and local codes. Ground currents are higher than 3mA.
Safety Guidelines
1.Disconnect the drive and vertical bypass/non bypass panel from mains before commencing service work
2.DO NOT touch electrical parts of the vertical bypass/non bypass panel or drive when mains is connected. After mains has been disconnected, wait 15 minutes before touching any electrical components or read the label on vertical bypass/non bypass panel.
3.The user must be protected against supply voltage and the motor must be protected against overload in accordance with applicable national and local regulations.
4.While programming parameters, the motor may start without warning. Activate the [Off] key on the LCP when changing parameters.
5.The [Off] key on the LCP does not isolate the drive from mains voltage and is not to be used as a safety switch.

1 Introduction
1.1.1 Purpose of the Manual
This manual is intended to provide detailed information for the installation and operation of the vertical panel used in conjunction with a Danfoss variable frequency drive (VFD). To enable efficient handling of the equipment, requirements are provided for installation of mechanical, electrical, control wiring, proper grounding, and environmental considerations. Pre-start and start up procedures are detailed. Also included is a detailed overview of the panel bypass function. In addition, identification of other optional components and their operation and start up troubleshooting instructions are included. For the electronically controlled bypass, additional programming and operation information is provided.
1.1.2 Overview
A variable frequency drive regulates the speed and operation of an electric motor. The drive is programmable and offers many features and savings compared to operating a motor from unregulated line voltage. The panel is a protective enclosure in which the drive and various optional components are assembled and mounted. The vertical non bypass panel is always configured with a disconnect switch and fuses to protect the drive. The vertical bypass panel allows switching between running the motor from the drive (variable speed) or across the line input power (constant speed).
The vertical bypass panel comes with one of two control options:
•The electromechanical bypass (EMB2)
•Electronically controlled bypass (ECB)
The EMB2 is operated by a selector switch on the front of the panel. The EMB2 controls a motor by switching between drive control, operation in bypass, or off. In addition, a test selection is available, which disengages the motor from the drive but keeps the drive operational while the motor runs in bypass. The switching function activates contactors to provide power to the motor through the drive or bypass circuitry, as required.
The ECB also uses contactors to provide power to the motor through the drive or bypass circuitry. However, the ECB contains a local processor that interacts with the drive’s control logic for programmable options, remote
1 1
inputs, and status reporting. The VFD’s logic circuitry is backed up by an independent panel-mounted power supply so that, even if the drive loses power, control and communication functions are maintained. Programming and display are provided by the LCP. An important feature of the ECB is the ability to accept commands from a building automation system (BAS) and to report operational status in return.
See more detailed descriptions of the EMB2 in 5 Electromechanical Bypass (EMB2) Operation and ECB in 6 Electronically Controlled Bypass (ECB) Operation of this manual.
1.1.3 Typical Bypass Operation
With contactors M1 and M2 closed and contactor M3 open, the motor is running in drive control. Opening contactor M2 removes power to the motor but allows the drive to remain under power. This is referred to as test mode. With contactors M1 and M2 open and contactor M3 closed, the motor is running in bypass from the line input power.
1.2 Bypass Circuits
1.2.1 Three-contactor Bypass
The bypass circuit consists of a bypass contactor (M3) interlocked with a drive output contactor (M2), a drive input contactor (M1), and an overload relay. For the EMB2, a door mounted Drive/OFF/Bypass/Test Selector switch is used to electrically select whether the motor is powered by the drive, connected to the full speed bypass, or disconnected from both. The test position applies power to the motor through the bypass (M3 closed) contactor but removes power from the drive (M2 open) while keeping the drive powered (M1 closed). A Pilot light indicates when in bypass. For the ECB, control selection is made through the drive keypad by pressing the DRIVE BYPASS key and selecting from the available options shown. Display data indicates when in bypass. The circuitry may be supplied with either an input disconnect switch or an input circuit breaker.

1.3 Bypass Options
1.3.1 Common Run/Stop with Bypass
Allows a remote signal to initiate operation in either drive control or bypass depending upon the position of the bypass selector switch.
1.3.2 Automatic Bypass
This feature automatically transfers the motor from drive to bypass without operator intervention when a fault condition trips the drive, after a programmable time-out period. The VFD’s internal fault circuitry controls this action. The time delay permits all automatically resettable faults to clear prior to transfer to bypass. Run permissive or safety circuit signals override the auto bypass function and may prevent or delay bypass operation.
1.3.3 Run Permissive in Bypass
With run permissive active, the drive sends a run request and waits for a remote response before commanding the motor to start. The response indicates the system is safe to operate.
1.3.4 Basic Fire Mode in Bypass
This option switches the panel to bypass whenever a remote fire mode signal is given to the VFD through the input terminals. In either drive or bypass, fire mode is intended to ignore common safety and overload inputs for emergency situations. The motor will continue to run in bypass until fire mode is removed or the drive, panel, or motor fails. External safety signals and motor overload are ignored when in fire mode.
1.3.5 Advanced Fire Mode in Bypass
The advanced fire mode allows for a variety of programmable responses to an external fire mode command signal. Bypass options are programmed through the drive’s fire mode parameters. See 6.1.13 ECB Advanced Fire Mode.
1.3.6 Overload Protection
This thermally activated device provides mechanical overload protection for the motor while in bypass operation. It measures motor current and is set to the full load amps (FLA) of the motor. A 1.2 x FLA service factor is built-in and maintained, meaning that should the motor current increase above that value, the overload will calculate the level of increase to activate timing for the trip function. The higher the current draw, the quicker the trip response. The overload provides Class 20 motor protection.

Figure 1.2 Basic Bypass Circuit
1.5 Switch Mode Power Supply
The VFD’s logic circuitry is backed up by an independent panel-mounted switch mode power supply so if the drive loses power, control and communication functions are maintained. The SMPS converts three-phase AC input power to 24 V DC control power. Since the SMPS draws power from all three phases, it offers immunity protection from most phase-loss and brown-out conditions. The SMPS is internally protected from short circuit on its output and three board-mounted fuses provide additional protection. The SMPS is not designed for external use and may take up to 5 sec. to initialize at power-up. The SMPS will maintain a 24 V DC output with a low input line voltage. The 200 Volt SMPS will maintain the 24 V DC output with a line voltage as low as 150 V AC and the 600 V SMPS to 335 V AC. Refer to Figure 1.2.
1.5.1 Control Transformer
A control transformer is included on larger horsepower units where the contactor coils are AC. The control transformer steps down the line input voltage to 120V AC. The coils of AC contactors are isolated from the Switch Mode Power Supply via relays.
1.6 Disconnects
1.6.1 Main Disconnect
The main disconnect removes line input power to the drive and bypass. A main disconnect is available in four options.
•Fused disconnect. Two-position (ON/OFF) rotary switch, padlock compatible, with three fuses, one on each phase, built into the switch. For safety, the switch must be in the OFF position before

When in the ON position, a trip fault removes power from the drive/bypass circuit and the switch moves to the TRIP setting. The switch must be moved to the RESET position momentarily after the fault has been cleared to reset the circuit breaker. (Bypass panel only.)
Main Disconnect with drive fuses. Non-bypass panel two-position (ON/OFF) rotary switch that disconnects the main AC line power to the drive only.
1.6.2 Mode Selector Switch
The mode selector switch is used for 3-contactor bypass on EMB2 units. The selector switch allows the operator to select from four modes of operation.
Drive mode: When drive mode is selected, the M1 and M2 contactors are closed allowing power to flow in and out of the drive to the motor.
Off mode: This mode opens all contactors removing any power to the motor.
Bypass mode:When bypass mode is selected, the M3 contactor closes and allows the motor to run directly from the input line power.
Test mode:Test mode closes the M1 and M3 contactors and allows the motor to be powered by the input line power. This also allows the drive to power up without being connected to the motor. Refer to Figure 1.2.

Table 1.4 Panel Voltage and Frame Ratings
1.7 Power Component Functions
1.7.1 Power Fusing
For main panel power fuses, only use the specified fuse or an equivalent replacement. For drive fuses only use the specified fuse. See the fuse ratings label on the inside cover of the unit or Table 3.2Table 3.3, Table 3.3Table 3.4, Table 3.4Table 3.5 and Table 3.5Table 3.6.
Main fusing
Main fuses are located ahead of the drive and bypass. Main fuses are designed to protect the circuitry within the bypass panel but is not adequate to protect the drive. Main fuses are dual-element, time-delay types and mount inside the bypass enclosure.
Drive fusing
Drive fuses are located ahead of the drive and are a fastacting type. Drive fuses are standard in all bypass and nonbypass panels.
5,000 or 100,000 amp SCCR
The bypass panel supplied with a non fusible Main Disconnect Switch is 5,000 amps short-circuit current rating (SCCR). The bypass panel supplied with a Fusible disconnect or circuit breaker is 100,000 amp SCCR. The non bypass panel supplied with a non-fusible Main Disconnect is 100,000 amp SCCR. See the panel label for SCCR rating.
NOTE!
The 600 V circuit breaker option is 5,000 amp (SCCR).

2 Pre-installation
2.1.1 Receiving Inspection
Inspect the packaging and equipment closely when received. Any indication of careless handling by the carrier should be noted on the delivery receipt, especially if the equipment will not be immediately uncrated. Obtain the delivery person’s signed agreement to any noted damages for any future insurance claims. Ensure that the model number and power match the order and intended use for the drive.
IMPORTANT!
LOST OR DAMAGED GOODS
INSPECT THIS SHIPMENT IMMEDIATELY UPON ARRIVAL
If goods are received short or in damaged condition, insist on a notation of the loss or damage across the face of the freight bill. Otherwise no claim can be enforced against the transportation company. If concealed loss or damage is discovered, notify your carrier at once and request an inspection. This is absolutely necessary. Unless you do this the carrier will not entertain any claim for loss or damage. The agent will make an inspection and can grant a concealed damage notation. If you give the transportation company a clear receipt for equipment that has been damaged or lost in transit, you do so at your own risk and expense.
Danfoss is willing to assist you to collect claims for loss or damage, but willingness on our part does not make us responsible for collection of claims or replacement of material. The actual filing and processing of the claim is your responsibility.
<![if ! IE]><![endif]>130BX366.10
Figure 2.1 Sample Panel Label
Ensure that the model number and power match the order and intended use for the drive.
2.1.2 Pre-installation Check |
2 |
2 |
|
|
1.Compare panel model number to what was ordered.
2.Ensure each of the following are rated for the same voltage:
•Drive
•Panel
•Power line
•Motor
3.Ensure that the panel output rating is equal to or greater than motor total full load current for full motor performance.
•Motor power size and panel must match for proper overload protection.
•If panel rating is less than motor; full motor output cannot be achieved.
4.Check motor wiring:
•Any disconnect between drive and motor should be interlocked to drive safety interlock circuit to avoid unwanted drive trips.
•Do not connect power factor correction capacitors between the drive and motor.
•Two speed motors must be wired permanently for full speed.
• |
Y-start, -run motors must be wired |
|
permanently for run. |
2.1.3 Installation Site Check
•Because the panel relies on the ambient air for cooling, it is important to observe the limitations on ambient air temperature. Derating concerns start above 104°F (40°C) and 3300 feet (1000m) elevation above sea level.
•It is important with multiple panels to check wall strength. Make sure that the proper mounting screws or bolts are used.
•Ensure that the wall or floor area for installation will support the weight of the unit.
•If construction work continues after the equipment is mounted, it is important to keep the interior free from concrete dust and similar

|
dirt. If the unit does not have power applied to it, |
|
|
|
supply a protective covering. It is important to |
|
|
|
ensure that the components stay as clean as |
|
2 |
2 |
possible. It may be necessary to clean the interior |
|
once construction is completed. |
|
||
|
|
|
•Keep drawings and manuals accessible for detailed installation and operation instructions. It is important that the manuals be available for equipment operators.
2.2Harsh Environments
The mechanical and electrical components within the panel can be adversely affected by the environment. The effects of contaminants in the air, either solid, liquid, or gas, are difficult to quantify and control.
2.2.1 Airborne Liquids
Liquids in the air can condense in components. Water carried in the air is easily measured as relative humidity, but other vapors are often more difficult to measure or control. Steam, oil and salt water vapor may cause corrosion of components. In such environments, use TYPE 12 enclosures to limit the exchange of outside air into the option enclosure. Extremely harsh environments may require a higher level of protection.
2.2.2 Airborne Solids
Particles in the air may cause mechanical, electrical or thermal failure in components. A TYPE 1 enclosure provides a reasonable degree of protection against falling particles, but it will not prevent the fan from pulling dirty air into the enclosure.
2.2.3 Corrosive Chemicals
In environments with high temperatures and humidity, corrosive gases such as sulfur, nitrogen and chlorine compounds cause corrosion to occur in components. Indications of corrosion are blackened copper or rust on steel or oxidized aluminum. In such environments, it is recommended that the equipment be mounted in a cabinet with fresh air ventilation and that corrosive compounds be kept away. A non-ventilated cabinet fitted with an air conditioner as a heat exchanger may be used. Conformal coated circuit boards may be specified to reduce the corrosive effects of a harsh environment.

3.2.1 Lifting
Check the weight of the unit before attempting to lift. Ensure that the lifting device is suitable for safely lifting the panel. If necessary, plan for a hoist, crane or forklift with appropriate rating to move the units.
3.2.2 Hoist or Overhead Lift
•Use a solid steel spreader bar for lifting. Slide the spreader bar through the two (2) lifting holes on the panel. Lifting rings are 0.59in (15mm) in diameter (see Figure 3.1). If VFD mounting screws interfere with the spreader bar, lifting hooks can be used instead of the lifting bar.
•Connect the spreader bar to a hoist or other lifting device.
•Carefully lift the unit and secure it to the wall. Refer to 8 Appendix for dimensional drawings to determine fasteners size and location.
3.2.3 Forklift
•Only a competent lift operator with additional support personnel should attempt moving the unit.
•Carefully position forklift and ensure stability prior to lift.
3.2.4 Shipping Weights
Weights listed in Table 3.7 are approximate for base units. Options can add or reduce weight of unit. Weights listed are in lbs.

Most panels may be mounted side-by-side |
|
|
|
|
|
|
|
without additional side clearance. However, the |
|
|
|
P2 (B3 frame size) units require 1.5 in. minimum clearance between units (see Figure 3.2).
CEILING
AIRFLOW
•Top and bottom clearance is required for cooling (see Figure 3.3). Generally, 2 to 10 inches (50 to
250mm) minimum clearance is required, depending upon the hp (kW) of the unit. See the dimensional drawings in 8 Appendix for specific requirements.
•No additional back plate is required for drives
with the bypass and non bypass panels.

3.4 Electrical Installation
WARNING
EQUIPMENT HAZARD!
Rotating shafts and electrical equipment can be hazardous. It is strongly recommended that all electrical work conform to all national and local regulations. Installation, start-up and maintenance should be performed only by qualified personnel. Failure to follow local regulations could result in death or serious injury.
•Motor control equipment and electronic controls are connected to hazardous line voltages. Extreme care should be taken to protect against electrical hazard.
•Correct protective grounding of the equipment must be established. Ground currents are higher than 3mA.
•A dedicated ground wire is required.
•Wear safety glasses whenever working on electric control or rotating equipment.
NOTE!
Make all power connections with a minimum of 60°C/ 140°F rated copper wire.
WARNING
INDUCED VOLTAGE!
Run output motor cables from multiple drives separately. Induced voltage from output motor cables run together can charge equipment capacitors even with the equipment turned off and locked out. Failure to run output motor cables separately could result in death or serious injury.
NOTE!
Run input power, motor wiring and control wiring in three separate metallic conduits or raceways for high frequency noise isolation. Failure to isolate power, motor and control wiring could result in less than optimum drive and associated equipment performance.
•Because the motor wiring carries high frequency electrical pulses, it is important that no other wires are run together. If the incoming power wiring is run in the same conduit as the motor wiring, these pulses can couple electrical noise back onto the building power grid.
At least three separate conduits must be connected to the panel (Figure 3.4).
•Power into the panel (and ground back to the distribution panel)
•Power from the panel to the motor and earth insulated motor ground
•Control wiring
Control wiring should always be isolated from the high
voltage power wiring. 3 3
Avoid getting metal chips into electronics.
Follow the connection procedures as illustrated in the drawing provided with the unit.
