Caution: For proper and safe installation, the input power cable must be connected to a fused circuit on the
vehicle. This fused circuit requires a five Amp maximum time delay (slow blow) high interrupting
rating fuse. 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 positive (+) terminal. Note: For North America, a UL
Listed fuse is to be used.
Caution: Usage in areas where moisture can affect the power supply connections should be avoided. The
power supply should be mounted in a dry location within the vehicle or placed in a suitable protective
enclosure.
Caution: For installation by trained service personnel only.
Warning: Risk of ignition or explosion. Explosive gas mixture may be vented from battery. Work only in well
ventilated area. Avoid creating arcs and sparks at battery terminals.
