CAUTION - For installation by trained service personnel only.

Use caution when routing the power cable. See Power Cable Cautions (page 4-14).

Fuse Requirements

WARNING - For proper and safe installation, the input power cable must be connected to a fused circuit on the vehicle. If the supply connection is made directly to the battery, the fuse should be installed in the positive lead within 5 inches of the battery’s positive (+) terminal. The fused circuit requires a maximum time delay (slow blow) fuse with a current rating as noted below.

•For 12VDC input, use a 10A slow blow fuse that has a DC voltage rating greater than 12VDC.

•For 24VDC input, use a 6A slow blow fuse that has a DC voltage rating greater than 24VDC.

•For 36VDC input, use a 4A slow blow fuse that has a DC voltage rating greater than 36VDC.

•For 48VDC input, use a 3A slow blow fuse that has a DC voltage rating greater than 48VDC. Note: For North America, a UL Listed fuse is to be used

Power Cable Identification

The DC power cable (included with the dock) is one of the two styles below:

Power cable with right angle connector and 6 wires:

!Twist the red and red/white wires together and twist the black and black/white wires together before connecting to vehicle power.

Power cable with straight connector and 4 wires:

Note: Correct electrical polarity is required for safe and proper installation. See the figures below for additional wire color-coding specifics.

The Thor VM1 DC input wires (Red, Red/White DC+ and Black, Black/White DC-) and the Blue ignition input wire are galvanically isolated. The Green ground input is used for electrostatic discharge (ESD) protection.

Vehicle 10-60VDC Direct Power Connection

1.The Thor VM1 must not be mounted in the Quick Mount Smart Dock. The power switch on the dock must be turned Off. The power cable must be UNPLUGGED from the dock.

2.While observing the Fuse Requirements (see page 4-15),connect the power cable as close as possible to the actual battery terminals of the vehicle (if using unswitched power).

3.Use proper electrical and mechanical fastening means for terminating the cable. Properly sized “crimp” type electrical terminals are an accepted method of termination. Please select electrical connectors sized for use with 20AWG (0.81mm2) conductors.

4.Refer to the wiring diagrams following this section for wire colors and connections:
