Mounting Optional, Battery Connection Standard

Mounting (Optional*)

(See Diagram 2, p. 32).

User must supply all fasteners and brackets and verify their suitability for use with the intended mounting surface. Turn your APS PowerVerter and connected equipment OFF before mounting.

•Install two 8 mm (1/4 in.) fasteners (A) into a rigid horizontal surface using the measurements in the diagram. Leave the heads of fasteners raised slightly above the surface in order to engage the slots in the APS’s feet.

•Slide PowerVerter forward to fully engage the fasteners in the APS’s feet. Install two 8 mm (1/4 in.) fasteners (B) into the surface, through the slots in the APS’s two unsecured feet. Tighten the screws to secure the APS in position.

*Horizontal mounting should be used for all vehicular applications. Due to their size and weight, all APS PowerVerter systems in vehicles should be mounted on a rigid horizontal (not vertical) surface, mounting plate or bracket before battery connection.

Battery Connection (Standard)

1. Connect your APS’s positive DC Terminal directly to a fuse.

UL recommends that you install a recognized UL component fuse block and fuse within 18 inches of the battery. The fuse's rating must equal or exceed the Minimum DC Fuse Rating listed in your APS model's specifications on pages 14 or 15.

2.Choose a battery configuration appropriate to your batteries.

•Single Battery Connection: Refer to Diagram 4, page 33. When using a single battery, its voltage must be equal to the voltage of your APS's Inverter Nominal Input Voltage (see specs).

•Parallel Battery Connection: Refer to Diagram 5, page 33. When using multiple batteries in parallel, each battery's voltage must be equal to the voltage of your APS's Inverter Nominal Input Voltage (see specs).

•Series Battery Connection: Refer to Diagram 6, page 33. When using multiple batteries in series, all batteries must be equal in voltage and amp hour capacity, and the sum of their voltages must be equal to the voltage of your APS's Inverter Nominal Input Voltage (see specs).

3.Use 2/0 gauge wire ONLY to make external battery connections. Tighten battery terminals to a torque of 4 N-m.

WARNING! Failure to follow these instructions can lead to product failure due to excessive heating!

Battery connection cable lengths should be short as possible, and must not exceed the Maximum Cable Length listed under Specifications, page 14. Shorter and heavier gauge cabling limits DC voltage drop and allows for maximum transfer of current.* You must tighten your battery terminals to approximately 4 Newton-meters of torque to create an efficient connection and prevent excessive heating. Insufficiently tightening terminals could void your PowerVerter's warranty.

*APS models are capable of delivering a much higher wattage output for brief periods of time. Wiring should be configured to handle this brief high-current draw. Though your APS is a high-efficiency converter of electricity, its rated output capacity is limited by the length and gauge of the wires running from the battery to the APS.

Battery Connection (DC Vehicular)

APS systems may be permanently mounted in a car, truck or boat and connected to draw power from the vehicle's battery. Note: An APS can ONLY be connected to vehicle batteries with voltage that matches the APS's Nominal DC Input—12V vehicle batteries to 12V Nominal DC Input APS systems, etc. (See Specifications). There are two main ways to make this sort of
