 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).
