Installation Instructions

Secure Racking

If Secure Racked units are installed in a closed or multi-unit rack assembly, they may require further

evaluation by Certication Agencies. The following items must be considered.

1. The ambient within the rack may be greater than room ambient. Installation should be such
that the amount of air ow required for safe operation is not compromised. The maximum
temperature for the equipment in this environment is 55°C. Consideration should be given to the
maximum rated ambient.

2. Installation should be such that a hazardous stability condition is not achieved due to uneven
loading.

Input Supply

Check nameplate ratings to assure there is no overloading of supply circuits that could have an effect
on overcurrent protection and supply wiring.

Grounding

Reliable earthing of this equipment must be maintained. Particular attention should be given to
supply connections when connecting to power strips, rather than direct connections to the branch
circuit.

No Serviceable Parts Inside; Authorized Service Personnel Only

Do not attempt to repair or service this device yourself. Internal components must be serviced by
authorized personnel only.

Disconnect Power

If any of the following events are noted, immediately disconnect the unit from the outlet and contact
qualied service personnel:

1. If the power cord becomes frayed or damaged.

2. If liquid has been spilled into the device or if the device has been exposed to rain or water.

Two Power Supply Cables

Note that PTS Series units feature two separate power circuits, and a separate power supply cable for
each power circuit. Make certain to disconnect both power supply cables before attempting to service
or remove the unit.

15-Amp "Starter" Cable

Depending on your specic model, PTS Series units may be shipped with either one or two 125 VAC,
15 Amp "Starter" Cables. These Starter Cables will allow you to connect the PTS to power for bench
testing and initial start up and are adequate for applications that only require 15 Amps. For 20-Amp
power switching applications, please refer to the WTI Power Cable guide supplied with the unit, or
use appropriate 20-Amp cables.

Units with Attached Power Supply Cable(s)

For units with xed Power Cords the socket-outlet shall be installed near the equipment and shall be
easily accessible.

1. Introduction

This Quick Start Guide describes the installation procedure for the PTS series
hardware. The PTS is essentially a power fallback switch, that automatically
switches power from a primary input to a secondary input when power to the
primary input is lost or interrupted.

2. Hardware Installation

Apply Power to the MPC

Refer to the warnings and cautions at the beginning of this guide and the
power rating nameplate on the PTS back panel, and then connect the unit to
two appropriate power sources. For units with detachable power input cables,
connect the power input cables to the power inlets, install the cable keepers, and
then connect the primary power input cable to your primary power supply and
the secondary power input cable to your secondary power supply. Refer to the
table below for information concerning power requirements and maximum loads.

Power Input Feeds:

• PTS-8NE15-1: Two (2) IEC-60320-C14 Inlets.

• PTS-9CM20-2: Two (2) IEC-60320-C20 Inlets.

Notes:

• After connecting your power cables to the PTS unit, make certain to
secure the cables in order to prevent accidental disconnection.

• PTS-1 series units are designed for switching power input lines that
are typically 120 VAC. If a power input lower than 120 VAC is
connected to a PTS-1 unit, then power switching features will not
function correctly.

• PTS-2 series units are designed for switching power input lines that
are typically 240 VAC. If a power input lower than 240 VAC is
connected to a PTS-2 unit, then power switching features will not
function correctly.

3. Operation

When properly installed, the PTS will automatically switch power from the
primary input to the secondary input when the power to the primary input is
interrupted. After switching from primary to secondary, the PTS will also switch
power back to the primary input when power to the primary input is restored.
Note that the "Input Power" LEDs on the PTS front panel will light to indicate
which power input is active. If the "Primary" LED is lit, this indicates that the
Primary Power source is active; if the "Secondary" LED is lit, this indicates that
the Secondary power source is active.

FCC Part 15 Regulation

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 in a residential installation. This equipment generates, uses, and can
