2.4 Operating the device safely

D

• Lay the cables so that they cannot be tripped over or damaged.

NOTICE!

• Use ductwork or cable ducts if it is necessary to lay cables through

metal panels or other panels with sharp edges.

• Do not lay the 230 V mains cable and the 12 V DC cable in the same

duct.

• Do not lay the cable so that it is loose or heavily kinked.

• Fasten the cables securely.

• Do not pull on the cables.

DANGER! Danger of electrocution

• Do not touch exposed cables with your bare hands. This applies espe-

cially when operating the device from the AC mains.

• To be able to disconnect the device quickly from the mains, the socket

must be close to the device and be easily accessible.

!

!

WARNING!

• Only use the device in closed, well-ventilated rooms.

• Do not operate the device in systems with lead acid batteries. These

batteries give off explosive hydrogen gas that can be ignited by sparks
on electrical connections.

CAUTION!

• Do not operate the device

– In salty, wet or damp environments
– In the vicinity of corrosive fumes
– In the vicinity of combustible materials
– In areas where there is a danger of explosions.

• Before starting the device, ensure that the power supply line and the

5 Technical description

The mains rectifier can operate all coolers and refrigerators with BDF 50 compressors
at 110 – 240 Vw. With a 110 – 240 Vw mains connection, the rectifier automatically
switches from battery to mains operation.

When disconnected from the 110 – 240 Vw mains supply, the rectifier automatically
switches back to battery operation. Mains operation via the rectifier always takes
priority over battery operation.

Mounting the mains rectifier MPS50

6 Mounting the mains rectifier

If you wish to mount the mains rectifier in a fixed position, please observe the
following mounting instructions:

• Do not mount the device

– In wet or damp environments
– In the vicinity of combustible materials
– In areas where there is a danger of explosions

• The place of installation must be well-ventilated. A ventilation system which is at

least equivalent to the air openings in the device must be present for installations
in closed housings.

• The air intake on the underside or the air outlet on the back of the device must

remain clear.

• The installation surface must be level and sufficiently sturdy.

➤ Secure the mains rectifier with screws through the fastening holes at the front and

the back of the device (fig. 1 3, page 9).

7 Using the mains rectifier

WARNING!

!

A

Do not reverse the polarity. If the poles are reversed device may over­heat and be damaged.

NOTICE!

Replace defective fuses with new ones of the same rating (12 A slow­blow).

WARNING!

!

To avoid drops in voltage and therefore performance, keep the cable route as short
as possible and only disconnect it when necessary.

The cables between mains rectifier and compressor must not exceed 1.5 m and must
have a cross section of at least 2.5 mm².

Ensure that the battery’s positive supply line is secured with a fuse
(fig. 2 1, page 11) of the following value:

• at 12 Vg: 15 A

• at 24 Vg: 7.5 A

The fuse must be installed as close to the battery as possible.
