Engel MHD13F-DM - Direct Wiring for Permanent Vehicle Installation; Wire Gauge for Voltage Drop Prevention; Fuse Installation for Wiring Circuit Protection

DIRECT WIRING FOR PERMANENT VEHICLE INSTALLATION (OPTIONAL)
①TWIST THE LEAD WIRE
To further reduce the radio interference during DC operation, twist the negative and positive
cables (use separate cables) together into a spiral form, between the battery and the DC outlet
socket (see Fig 4)
②CONNECT PRODUCT DIRECT TO BATTERY
Any switches and leadwires for other electrical equipment should not be shared with the wiring
between the product and battery. (Other equipment can generate high voltage pulses which
may cause transistor damage to the fridge power supply.)
③TO PREVENT RADIO NOISE AND AVOID ABSORBING HIGH SURGE FREQUENCY.
Insert a capacitor. (10000μF) (see Fig 5)
④ WIRE GAUGE IS IMPORTANT TO AVOID“VOLTAGE DROP”
Connect the product to the battery as follows:

⑤INSTALLING A FUSE IN THE WIRING CIRCUIT
To avoid burn out of wiring from battery to the product in the event of a short circuit, install 10A
fuse in the wiring circuit, nearby the battery.
⑥Never connect the product directly to an engine generator.
The product will be damaged by high voltage and high surge pulse from the power
source, please utilize an automatic voltage regulator for the product. Please contact your
