USER MANUAL
Safety Summary
The following safety precautions apply to both operating and maintenance personnel and must be observed during all phases of operation, service, and repair of this instrument. Before applying power, follow the installation instructions and become familiar with the operating instructions for this instrument.
If this device is damaged or something is missing, contact the place
of purchase immediately.
This manual contains information and warnings that must be followed to ensure safe operation as well as maintain the meter in a safe condition.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical ground. This instrument is grounded through the ground conductor of the supplied, three­conductor ac power cable. The power cable must be plugged into an approved three-conductor electrical outlet. Do not alter the ground connection. Without the protective ground connection, all accessible conductive parts (including control knobs) can render an electric shock. The power jack and mating plug of the power cable must meet IEC safety standards.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or fumes. Operation of any electrical instrument in such an environment constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS
Instrument covers must not be removed by operating personnel. Component replacement and internal adjustments must be made by qualified maintenance personnel. Disconnect the power cord before removing the instrument covers and replacing components. Under certain conditions, even with the power cable removed, dangerous voltages may exist. To avoid injuries, always disconnect power and discharge circuits before touching them.
DO NOT SERVICE OR ADJUST ALONE
Do not attempt any internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY THE INSTRUMENT
Do not install substitute parts or perform any unauthorized modifications to this instrument. Return the instrument to B&K Precision for service and repair to ensure that safety features are maintained.
WARNINGS AND CAUTIONS
WARNING and CAUTION statements, such as the following
examples, denote a hazard and appear throughout this manual. Follow all instructions contained in these statements.
A WARNING statement calls attention to an operating procedure, practice, or condition, which, if not followed correctly, could result in injury or death to personnel.
WARNING:
Do not alter the ground connection. Without the protective ground connection, all accessible conductive parts (including control knobs) can render an electric shock. The power jack and mating plug of the power cable meet IEC safety standards.
WARNING:
To avoid electrical shock hazard, disconnect power cord before removing covers. Refer servicing to qualified personnel.
CAUTION:
Before connecting the line cord to the AC mains, check the rear panel AC line voltage indicator. Applying a line voltage other than the indicated voltage can destroy the AC line fuses. For continued fire protection, replace fuses only with those of the specified voltage and current ratings.
CAUTION:
This product uses components which can be damaged by electro­static discharge (ESD). To avoid damage, be sure to follow proper procedures for handling, storing and transporting parts and subassemblies which contain ESD-sensitive components.
A CAUTION statement calls attention to an operating procedure, practice, or condition, which, if not followed correctly, could result in damage to or destruction of part or all of the product.

1 General Information

1.1 Product Overview

The 917xB and 918xB series are high-performance dual range linear DC power supplies that provide clean and reliable power with high resolution and accuracy. All models are programmable via standard USB interface or optional RS232, GPIB and LAN interface. Interface cards and I/O cards come in a modular form factor. Selected models feature high voltage outputs or dual channels to provide series/parallel tracking functionality. All models include front and rear panel outputs for flexibility, and feature programmable list mode for storing and running customized test sequences. Additionally, a unique LED test mode function can be enabled for LED test applications requiring minimal inrush current output. These power supplies are suitable for bench or rack mount operation with the
available rack mount kit option.
Features

1.7 Installing Optional Interface Cards

Five optional interface cards are available and can be installed in
either the S1 or S2 slots. They are:
Option 1: GPIB/LAN Card
Adds GPIB and LAN interface
Option2: DIO/Analog Card (Single channel)
Adds digital I/O and External Analog Control
Option 3: DIO/Analog Card (Dual channel)
Adds dual channel digital I/O and External Analog Control
Option 4: RS485 Card
Adds RS-485 interface for multi power supply control
Option 5: RS232 Card
Adds RS-232 interface

How to Install Interface Cards

1. Power off the instrument and disconnect the AC power cord in the rear panel. Remove the back faceplate covering the S1 or S2 slot in the rear panel by removing the two screws on each side.

2. Make note of the metal notches that indicate where the card should slide into. Inside the slot, there are two rails (left and right side) where the card should slide smoothly into. The very back of the slot is a 48-pin female connector that should connect with the 48-pins on the back of the interface card.
3. The interface card should go right below the metal notches on both sides and fit in between the inner card rails, also on both sides. Slide the card down carefully. When it touches the 48-pin connector, slowly push the card all the way in until the panel of the interface card aligns with the rear panel of the power supply.

4. Place the two screws to tighten and secure the installed card.
5. Connect the power cord and turn on the power supply. The newly installed card will be detected during boot up, indicated next to S1: or S2: (depending on which slot the card is installed into).

Removing Interface Cards

1. Power off the instrument and disconnect the AC power cord in the rear panel. Remove the two screws on each side of the installed interface card.
2. Use a flat blade screwdriver to gently pry the left and right side of the interface card plate. When there is enough room, use the screwdriver to pry the top part of the card until the card has slid out with enough room to pull out the card by hand.
3. Be sure to ground yourself before pulling out or touching any parts of the printed board on the interface card.

1.8 Rackmount Installation

There are four rackmount kit options available for this series of
power supplies: 2U size for single power supply, 2U size for two
power supplies mounted side by side, 3U size for single power
supply, 3U size for two power supplies mounted side by side. The
following step by step instructions will guide you in installing these
optional rackmount kits onto the power supply for a standard 19-inch
rack fitting.
Models 9171B, 9172B, 9181B: Follow instructions for 2U
rackmount installation.
Models 9173B, 9174B, 9182B, 9183B, 9184B, 9185B: Follow
instructions for 3U rackmount installation.
