DANGER

Risk of Electrical ShockTo reduce the risk of electrical shock and to ensure the safe operation of the ATS/GTS, the symbols

below are used throughout this manual. Where they appear, only qualied personnel should carry out

these instructions.

A dangerous voltage exists in this area. Use extreme caution at all times.

Attention: Important operating instructions. Follow them exactly.


5/16

1

The ATS and/or GTS are to be installed by people trained in the safe use of high-energy

power supplies and their batteries. Also assumed is knowledge of the local electrical

code(s) and their safe application.

DANGER: NEVERlet water from rain, a hose, tap or a sprinklers output, road splash or

other water sources enter the enclosure of the ATS/GTS to prevent accidental shorts,

shocks or electrocutions.

DANGER: This unit does NOT have an on/off switch. Whenever it is connected to line or

battery power, power is present at the output. Use extreme caution at all times.

Do not work alone under hazardous conditions.

Read this manual. If you have any questions about safe installation, operation or

maintenance, contact Alpha Technologiess customer service department.

Use this manual together with the Operators Manual of the UPS.

Carefully unpack the components. Report any shipping or other damage at once.

Always assume electrical connections or conductors are live. Turn off all circuit breakers

and double-check with a voltmeter before performing installation or maintenance.

Before installation, verify the input voltage and current requirements of the load are met by

the UPSs output (See specications). Verify the line voltage and current meet the UPSs

input requirements.

The ATS/GTS have more than one live circuit. AC power may be present at their outputseven if the UPS is disconnected from line or battery power.

The ATS/GTS can be operated to a maximum operating temperature of 55C.Also see the

specications section for temperature ratings.

At high ambient temperature conditions, the enclosures surface can be very hot to the

touch.

2 Overview

The Automatic Transfer Switch (ATS) (Figure 2.1) and the Generator Transfer Switch (GTS)

(Figure 2.2) are optional add-on switching units specically designed for (but not limited to) the

FXM family (FXM 650, 1100, 1500 and 2000) and the Novus Micro family (Micro 300/600/1000,

Standard, XL and XL3) of UPS. These switching units provide power and/or bypass capacity

(automatic or manual) so that the operator may safely disconnect the UPS from line or genera-tor power for easy removal and servicing. In bypass mode, the loads are directly connected to

the line or generator power without any conditioning. The ATS and/or GTS allow the use of 3

different back-up sources (line, batteries and/or generator).

3 Mounting the ATS/GTS

The ATS and GTS can be mounted as stand alone, chassis (e.g. on the external bottom enclo-

sure of the Novus Micro family UPS) or rack (e.g. inside the end system enclosure of the FXM

family UPS). The following diagrams illustrate some of the possible congurations.

Wiring the ATS/GTS to the UPS

The ATS/GTS should be wired to the UPS as shown in Figure .1 below.

The ATS/GTS/UPS end system must be correctly grounded for proper operation.

Older facilities may have inadequate electrical grounding. Inspection must be performedby a qualied electrician before installation to ensure that grounding meets the local

electrical code.

To provide branch circuit protection, the utility line attached to the ATS/GTS/UPSs

input MUST be protected by a circuit breaker certied for this use as per the local

or national electrical code.

The breakers minimum size is calculated by the following formula:

Minimum Breaker Size= UPSs maximum input current / 0.8

The units maximum input current is read off of the UPSs nameplate. For example, if thenameplate gives the maximum input current as 25A, the circuit breaker should be rated

at least 30A.

The input and output lines to and from the ATS/GTS/UPS system MUST have

disconnect devices attached.

If stranded wires are used, ferrules or equivalent crimping terminals must be used.

Servicing the UPS

ATS: Turn off CB1, SW1 and battery CB of the UPS.

GTS (UPS connected to Line Out): The main source branch CB protection coming either

from Generator or Line has to be turn-off. Likewise, battery CB of the UPS has to be turn-

off.

ATS and GTS combine: Turn off CB1, SW1 and battery CB of the UPS.

Other Note:

Simplex 5-15R receptacle is for 120V (rated 5A) only.

2 position mate and lock connector is for 230V only.

Emergency Shutdown Procedure

The ATS/GTS does not have an on/off switch. Whenever it senses battery or line

power, there is power present at the outputs and the unit is active.

1. Turn off the circuit breaker providing line power to the unit.

2. Disconnect the batteries from the UPS.

3. Turn OFF the attached generator (if connected).
