5.0 PREPARATION FOR USE
5.1 General
After unpacking, perform an initial inspection and preliminary electrical check to
ensure the instrument is in good working order. Notify the carrier immediately if
damage is found. Direct any repair problems to the service department listed at the
end of this document.
5.2 Initial Inspection
1. Inspect the instrument for exterior mechanical damage.
2. Inspect the input power cord and input power module for damage.
5.3 Electrical Installation
Standard PVX-4140 Bs are shipped ready for use with a nominal 110-240 VAC
input.
5.3.1 Input Power Cord
The input power cord terminates externally in a three-prong polarized plug. The
chassis is wired to the plug through the line cord, and therefore, the insertion of the
plug into a compatible receptacle, hooked up to a grounded input, will automatically
ground the instrument. The instrument should not be operated without a grounded AC
input!
5.4 Electrical Check
Before proceeding, please review the precautions in Section 3.
5.4.1 Power-Up
The PVX-4140 B should be powered up using the following procedures:
1. Insert the supplied DA-15 plug into the rear panel socket. As configured by the
factory, the plug has pins 4 and 12 jumpered to satisfy the interlock, and pins 5 and
13 jumpered to enable auto reset. Because pin 11 (Remote) is not grounded,
remote operation is disabled.
This plug must be installed in order to satisfy the
interlock circuit. If it is not installed, the instrument cannot be enabled.
To
operate the PVX-4140 remotely, or to use an external interlock, wire the DA-15
connector accordingly (see the “Remote Control” section above).

WARNING
: If the system is wired for Remote Control, the local mode can be
overridden by the remote user. For this reason, it is recommended to power off the
high voltage power supplies and when servicing the instrument.
