Electronic Emission Notices
Federal Communications Commission (FCC) Statement
Note: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause
harmful interference, in which case the user will be required to correct the interfer-
ence at his own expense.
Properly shielded and grounded cables and connectors must be used in order to
meet FCC emission limits. IBM is not responsible for any radio or television inter-
ference caused by using other than recommended cables and connectors or by
unauthorized changes or modifications to this equipment. Unauthorized changes or
modifications could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
For Canada, Canadian Department of Communication Statement, GX27-3883,

Safety
General Safety This product meets IBM safety standards.
For general safety information, see: IBM Telecommunication Products Safety
Handbook , GA33-0126.
Service Inspection Procedure
The following procedure helps the service representative check that the transformer
assembly conforms with IBM safety criteria. It is to be used whenever safety is
suspected.
Any deficiencies detected when using this procedure (if they make the transformer
unsafe) must be, either reported to the owner and/or user, or corrected by
exchanging the transformer assembly.
The areas checked by this procedure are:
1. Input power voltage
2. Circuit protector
3. Safety label
4. Power supply part number
5. Grounding
6. Covers.
Important Note
The transformer assembly is a sealed unit. It cannot be opened for mainte-
nance.
Procedure Steps
 Step 1 Input power voltage
– Check that the voltage indicated on the transformer assembly power rating
plate is consistent with the voltage level measured at the customer's power
receptacle. See Figure 1-2 on page 1-4 for location.
 Step 2 Circuit protector
– Check that the circuit protector is not damaged and physically operates cor-
rectly.
 Step 3 Safety label
– Check that the safety labels are present. See Figure 1-2 on page 1-4 for
location.
 Copyright IBM Corp. 1989, 1995 vii

 Step 4 Power supply part number
– Check that the part number written on the transformer assembly is con-
sistent with “Transformer Assembly Part Number” on page 1-8
 Step 5 Grounding
– Check that electrical continuity is assured between the ground wires of the
power cords and between those ground wires and the frame ground.
 Step 6 Cover
– The transformer assembly is a sealed unit. Check that the rivets are in
place and have not been forced.
viii RPQ 7L1184

Chapter 1. Generalities
Introduction This RPQ allows connecting an IBM 3745 Communication Controller Model 130,
150, 160, 170 or 17A or an IBM 3746 Expansion Unit Model 900 to a customer's
100/120-volt power supply.
It consists of a transformer with an input power cord with a plug and an output
power cord. Overload protection is provided through a circuit protector at the input.
The transformer assembly is a sealed unit. It cannot be opened for maintenance.

Installation 1. Measure the customer's primary power using the
3745-130/150/160/170/17A
and 3746-900 Installation Guide , SY33-2067, Chapter 2 "Measuring the Cus-
tomer's Primary Power", steps 1 through 3.
The acceptable voltage limits are: 90 through 127 volts. See “Input Voltages”
on page 1-7.
2. Ensure that the 3745 is not connected to the customer's power supply
Ensure that CB1 is switched to OFF on the front of the 3745 primary power box
(see Figure 1-3 for location).

On the front side of the primary power box, set the SW1 switch (see Figure 1-3
for location) to position 240.
3. If the machine is shipped with the 200/240-volts line cord installed, it must be
disconnected and removed.
a. Remove the clamp securing the power cord. Keep this clamp and its screw
for further use.
b. Disconnect the power cord from connector J3 (see Figure 1-4 on page 1-6
for location).

4. Place the transformer assembly according to “Service Clearances” on
page 1-2. The transformer must be installed above the raised floor (if present).
IMPORTANT
Ensure that the transformer is placed so that it will not cause a tripping
hazard. Place it against a wall, on or under a desk or table, away from
aisles.
5. Plug the output power cord of the transformer to connector J3. Secure the
cable with the clamp and screw removed in step 3a.
6. Route the input power cord to the customer's receptacle, and insert the power
plug into the customer's main socket.
7. Switch the transformer assembly circuit protector to the ON position.
8. Continue the 3745 installation using the Installation Guide Chapter 2, step 4 of
"3745 Connection to Customer's Primary Power".
Operation The transformer is a passive device requiring no action. The 3745 power
(ON/OFF) will still be controlled by the 3745 control panel. The circuit protector on
the transformer is for circuit protection only and should not be used as an ON/OFF
switch.
1-6 RPQ 7L1184

Maintenance In case of problems, the transformer assembly being a FRU, the entire assembly
must be exchanged. Before the exchange, check if the circuit protector is in the
ON position.
For part number assembly refer to “Transformer Assembly Part Number” on
page 1-8.
