TABLE OF CONTENTS 1. RECEIVING THE AT10.1 1.1. STORING THE AT10.1 If you store the AT10.1 for more than a few days before installation, you should store it in its original shipping container, and in a temperature controlled, dry climate. Ambient temperatures of 32 to 122° F / 0 to 50° C are acceptable. Storage should not exceed 2 years due to the limited shelf life of the dc filter capacitors when they are not in service. 1.2. REPORTING SHIPPING DAMAGE If, on delivery of the AT10.1 or r

INSTALLING THE AT10.1 1.5.1. Wall-Mounting the AT10.1 Wall-mounting the AT10.1 battery charger is the standard way to install the Group I enclosures (Style-586/594). In planning for wall mounting of the AT10.1 consider the following: 1. The wall must be strong enough to properly support the weight of the AT10.1. See the Weight Table located in section 1.4 on page 3. The weight of your AT10.1 may be different from the table value, depending on options or accessories you ordered. 2. Selec

INSTALLING THE AT10.1 1.6. CHANGING TRANSFORMER TAPS Before you wire ac power to the AT10.1, check the wiring of the main transformer T1, to be sure it is connected for your ac input voltage. The AT10.1 accepts standard input voltages of 120, 208 or 240 Vac by changing jumpers on T1. No other changes are required. The AT10.1 is wired at the factory for 240 Vac, except on special order. Models for 220, 380 or 416 Vac at 50/60 Hz are available on special order. EXCEPTION: An AT10.1 batte

INSTALLING THE AT10.1 1.7. MAKING THE AC INPUT CONNECTIONS Follow these steps to connect ac power to the AT10.1: 1. Use a branch circuit breaker or fused disconnect switch, properly sized for the maximum input current of the AT10.1, as shown in the table below. This device should have lockout capability so that the ac input can be de- energized and locked out for maintenance. A time delay circuit breaker or slow-blow fuse is recommended. 2. Size the ac input wiring per the National Electr

INSTALLING THE AT10.1 1.8. MAKING THE DC OUTPUT CONNECTIONS Follow these steps to connect the battery to the AT10.1: 1. Size the dc wiring to minimize voltage drop. The acceptable wire size depends on your installation. As a guideline, the voltage drop should not exceed 1% of nominal output voltage at full current. Refer to the table below to determine the voltage drops for various wire sizes, currents and distances. WIRE SIZING CHART VOLTAGE DROP PER 100ft / 30.5m OF WIRE (FOR COPPER

INSTALLING THE AT10.1 1.9. WIRING THE AT10.1 FOR REMOTE SENSING You can wire the AT10.1 to regulate the output voltage at the battery terminals, instead of at the charger output terminals. Remote sensing does the following: 1. Compensates for voltage drop in the dc wiring between the AT10.1 and the battery. 2. Directly monitors the battery or dc bus voltage. The front panel meter displays the actual voltage on the dc bus. You wire the AT10.1 for remote sensing by installing a two-wire c
