Safety instructions for handling and operation
INSTRUCTION
Damage to the DC/DC converter:
As a rule, it is to be ensured that the voltage ranges of all devices connected to the DC/DC
converter are identical.
Only use technically suitable and high-quality cables!
A high cooling water temperature and/or ambient temperature reduces the life span! Therefore,
ensure that the device is continuously cooled sufficiently!
Do not place the device in direct sunlight and in direct proximity to heat sources!
Even though the device has a high IP protection class, direct contact with water (rain, splashing
water) is to be avoided if possible!
Never damage existing galvanic isolations (e.g. by connecting HV contacts with the device
casing) in the vehicle.
Prevent any fluid ingress into the device (e.g. during assembly work). Fluid ingress will lead to a
short circuit and subsequently to damage to the device!
In the case of any fluid ingress, do not start the device and immediately contact the company
BRUSA Elektronik AG.
Always use an insulation monitoring unit to continuously monitor the galvanic isolation between
the HV and LV circuit!
Never connect or disconnect the HV connectors without ensuring the absence of voltage
beforehand!
Before connecting a voltage supply to the HV side of the DC converter (e.g.: HV battery), the
voltage must be pre-charged via a suitable pre-charging device,
see chapter
INFORMATION
The device may be used up to a maximum altitude of 4,000 m above sea level!
