SAFETY AND EMC GUIDELINES 2-3
SB1391 Hardware and Setup Guide - Document revision no. 1.14
Section 54.5: Not incorporating over-speed protection
Warning
Facilities for over-speed protection are not provided in the control unit.
Therefore, when facilities for over-speed protection are required for the end-
product, they will have to be provided separately by the end-user.
2.1.2. Branch Circuit Short Circuit Protection
Section 55.1: Short circuit rating and fuse information
Suitable for use on a circuit capable of delivering not more than 5,000 rms symmetrical amperes,
250 volts maximum.
2.1.3. Wiring Terminal Markings
Section 57: Wire Terminal Markings
Refer to FIGURE 4-2 Wiring diagram, for correct terminal connections. Chapter 4
MOUNTING AND WIRING, also contains all needed specifications regarding proper wire
type and size.
2.2. General Safety Guidelines
Under certain circumstances it is not enough to just power off the unit. For instance under
emergency situations the unit should be completely disconnected from any power supply. The E-
Stop and Left/Right Limits on ACS-Tech80 products are designed for use in conjunction with
customer installed devices to protect driver load. The end user is responsible for complying with
all Electrical Codes.
2.2.1. Emergency Stop
An emergency stop device shall be located at each operator control station and other operating
stations where an emergency stop may be required. The emergency stop device shall disconnect
any electrical equipment connected to the unit from the power supply. It will not be possible to
restore the circuit until the operator manually resets the emergency stop. In situations with
multiple emergency stop devices the circuit shall not be restored until all emergency stops devices
are manually reset.
2.2.2. Electrical Separation
Electrical separation is required between the control and power supply cables to prevent electrical
shock or damage to the equipment.
2.2.3. Over-Current Protection
Properly sized circuit breakers shall be used for over-current protection.
