Introduction

Section 2: Introduction

Overview of Operation

The Safety Automatic Transfer Switch (SATS) is an integral part of an Uninterruptible Power Supply

(UPS) or Battery Backup system. Its intended usage is to provide multiple sources of AC power in

order to operate trac signals, conict monitors, camera equipment, lighting, and additional appli-

cations used in Departments of Transportation and Intelligent Trac Systems (DOT/ITS). With utility

line voltage applied and an UPS activated, the SATS will automatically begin to power the load with

the UPS’regulated output voltage. It also allows the technician to perform utility line, UPS, or gen-

erator maintenance without disrupting power to the trac equipment. By utilizing AC utility power,

UPS power, and AC Generator power, the SATS will automatically determine which power source

to use to continuously power the load. In the event the AC utility line voltage is missing, and UPS

battery backup power has been depleted, an AC generator may be used to automatically power the

load. Normal operation will delay the use of generator power for 30 seconds after AC utility line and

UPS power loss to allow for AC generator initialization and startup. This allows the output voltage of

the generator to stabilize before use. The SATS comes in two models, one which mates specically

to Multilink’s EDP Double Conversion UPS’, and another universal model which mates to Line Inter-

active UPS’.

Safety Automatic Transfer Switch features:

• 120VAC/60Hz output.

• Duplex Outlet with 120V/60Hz/6Amp max to allow for additional equipment to be attached.

• Dry Contact relays to allow for monitoring of Utility line voltage and Generator power.

• UL/CSA and EMI/RFI Compliant.

All Safety Automatic Transfer Switches include:

• 1 SATS, ready for installation in cabinet

• 1 Power harness (four-wire for EDP series, six-wire for universal/Line Interactive)

• 1 7-position dry contact relay connector

• 1 User manual and instruction guide

Unpacking and Inspection

Before installing this equipment, inspect the SATS for shipping damage or missing components. If

the SATS or other items were damaged in shipment, le a damage claim with the shipping company

Installation and Setup

Section 4: Installation and Setup

Installing and wiring the Safety Automatic Transfer Switch into an enclosure may be accomplished by con-

necting the utility AC input wires and cabinet load wires to the appropriate connectors of the SATS. If in use,

the generator wires from the outside generator cabinet connector may also be wired to the appropriate

connector. The UPS power harness shall be used to connect the SATS to the UPS according to the wiring dia-

gram. The 7-position dry contact relay connector may be wired to sense the presence of power and report

this to a conict monitor when MAINS or GEN power is currently active or inactive.

In all installations, the following conditions apply and must be observed:

• A service disconnect switch containing over-current protection devices such as circuit breakers or

fuses with appropriate AIC (amperes – interrupting capacity) rating should be placed between the

AC utility source and the service entrance device for the SATS. Where used, the disconnect switch

must be installed in compliance with all national, state and local codes as required.

• For outdoor installations, the AC utility conductors connected to the cabinet service entrance de-

vice shall be physically protected through an appropriate restraining device and conduit, consistent

with local codes and practices.

• Permission to mount the SATS enclosure at any site shall be made in accordance with all legal re-

quirements and local practices of the area.

This SATS is designed for use in both existing and new ground-mount enclosures. Observe the following

procedures during installation of any SATS.

Preparation

e Safety Automatic Transfer Switch has been factory assembled, tested and prepared as a complete

product ready for installation within an enclosure. e installer must verify that the correct type of AC

power receptacle is installed in the enclosure for the input service and SATS selected for use at any giv-

en site. SATS ratings may be veried from the nameplate on the top of the SATS near the duplex outlet.

Grounding

Safety ground and earth ground connections must be in place for the SATS and enclosure for both per-

sonal safety and operational considerations. During SATS and/or enclosure installation, the following

grounding connections must be provided or veried.

10

Multilink Inc. 580 Ternes Ln. | Elyria,OH 44035 | 440.366.6966 | www.gomultilink.com

CAUTION

Failure to provide and connect adequate safety and earth grounds at each installation site may result in im-

proper SATS operation or permanent damage to the SATS itself. Grounding facilities and connections must

conform to appropriate national codes and/or local practices.

1.The AC utility conductors installed in the service entrance box must contain a safety ground conduc-

tor. The SATS installer should verify that this grounding conductor is in place, having been installed

along with the AC utility input.

2.A separate enclosure ground wire must be connected between the enclosure ground lug and an

earth ground connection provided by a ground rod installed at the SATS site. In most cases, one

copper or copper-clad steel ground rod of 2.5 meter (8 feet) length driven into the earth will be

sucient to provide the ground connection required. In some instances, a more elaborate ground-

ing method (such as a ring ground) may be required; however, this may be dictated by state or local

codes and depends on conductivity of the soil within the installation area.

3.The dead metal of the service entrance box must be bonded to the metal enclosure that houses the

SATS. Additionally, the ground bar within the service entrance box should be bonded to the metal

enclosures; however, this requirement may be subject to local codes and practices.

4.The grounding wire connected between the SATS enclosure and the earth ground rod should be no

smaller in area than 13 mm² (6 AWG) copper. Both ends of the ground wire should be sealed with an

appropriate anti-oxidation compound.

5.An optional ground bonding connection exists on the 7-position dry contact connector.

Placement in the Enclosure

This SATS has been designed primarily for use within a cabinet or enclosure oering protection from out-

door weather, entry of excessive dust, dirt or moisture, and from unauthorized contact by untrained person-

nel. If used in a controlled environment, the SATS may be located within an indoor equipment cabinet or

may be mounted on a rack shelf. Place the SATS within 36 inches of the line and load terminal block buses

inside the cabinet.

The SATS should be mounted on a ventilated shelf or rack that allows free air circulation, especially through

the right and left side panels of the SATS cabinet. Clearance of at least 1RU or 1.75 inches must be main-

tained around all surfaces of this SATS for unobstructed airow. Temperature of the air entering the SATS

should not exceed 74°C (165° F). System de-rating will occur at 55°C. See Specications.
