The protective characteristics of circuit breakers depend on the supply voltage as well as the type and construction of the breakers. There are also limitations pertaining to the short-circuit capacity of the supply network. Your local ABB representative can help you in selecting the breaker type when the supply network characteristics are known.
The user can tune the thermal model further by feeding in additional motor and load data. PTC sensors can be connected directly to the ACS850-04. See page in this manual, and the appropriate Firmware Manual for the parameter settings concerning motor thermal protection.

If not suppressed, the disturbances may connect capacitively or inductively to other conductors in the control cable and form a risk of malfunction in other parts of the system. Install the protective component as close to the inductive load as possible, not at the relay output.
Control panel cable The cable connecting the control panel to the drive must not exceed 3 metres in length. The cable type tested and approved by ABB is used in control panel option kits. Connection of a motor temperature sensor to the drive I/O See page 64.
Where control cables must cross power cables make sure they are arranged at an angle as near to 90 degrees as possible. Do not run extra cables through the drive. The cable trays must have good electrical bonding to each other and to the grounding electrodes.
Electrical installation What this chapter contains This chapter describes the electrical installation procedure of the drive. WARNING! The work described in this chapter may only be carried out by a qualified electrician. Follow the Safety instructions on the first pages of this manual. Ignoring the safety instructions can cause injury or death.

Installation of power cable clamp plates Two identical power cable clamp plates are included with the drive. The picture below depicts a frame size A drive; the installation is similar with other frame sizes. Note: Pay attention to supporting the cables adequately within the installation enclosure especially if not using the cable clamps.
DC connection The UDC+ and UDC– terminals are intended for common DC configurations of a number of ACS850 drives, allowing regenerative energy from one drive to be utilised by the other drives in motoring mode. One or more drives are connected to the AC supply depending on the power requirement.

Maintenance intervals The table below lists the routine maintenance intervals recommended by ABB. Consult a local ABB Service representative for more details. On the Internet, go to http://www.abb.com/drives, select Drive Services, and Maintenance and Field Services.
Heatsink The heatsink fins pick up dust from the cooling air. The drive runs into overtemperature warnings and faults if the heatsink is not clean. In a normal environment, the heatsink should be checked annually, in a dusty environment more often.
If the drive is operated in a critical part of a process, fan replacement is recommended once these symptoms start appearing. Replacement fans are available from ABB. Do not use other than ABB-specified spare parts.
Fan replacement (Frames C and D) To remove the fan, release the retaining clip (arrowed) carefully using a screwdriver. Pull the fan holder out. Disconnect the fan cable. Carefully bend the clips on the fan holder to free the fan. Install new fan in reverse order.
The capacitors must be reformed if the drive has been stored for a year or more. See page for information on finding out the manufacturing date. For information on reforming the capacitors, contact your local ABB representative. Other maintenance actions Transfering the memory unit to a new drive module When a drive module is replaced, the parameter settings can be retained by transferring the memory unit from the defective drive module to the new module.

CE marking A CE mark is attached to the drive to verify that the drive follows the provisions of the European Low Voltage and EMC Directives. Compliance with the European Low Voltage Directive The compliance with the European Low Voltage Directive has been verified according to standards EN 50178, EN 61800-5-1 and EN 60204-1.
The drive is intended to be incorporated into machinery to constitute machinery covered by Machinery Directive (98/37/EC) and does therefore not in every respect comply with the provisions of the directive. For more information, see the Declaration of Incorporation by ABB Drives (code 64652770). C-Tick marking Pending.
Overload protection – The drive provides overload protection in accordance with the National Electrical Code (US). Braking – The ACS850-04 has an internal braking chopper. When applied with appropriately sized braking resistors, the braking chopper will allow the drive to dissipate regenerative energy (normally associated with quickly decelerating a motor).
Mains chokes What this chapter contains This chapter describes how to select and install mains chokes for the ACS850-04. The chapter also contains the relevant technical data. When is a mains choke required? Frame C and D drive modules have an internal mains choke. With frames A and B, the need for an external choke should be determined on a case-by-case basis.
