5.5. Power connection
Caution:
 The following jobs are to be carried out only by qualified service personnel.
 Only connect the unit to a power socket with earthing contact (PE – protective earth)!
 Check the protection of the power supply net, and install 35 A fuses if necessary.
Do not use a higher value!
 Never operate equipment with damaged mains power cables.
 Regularly check the mains power cables for material defects (e.g. for cracks).
 We disclaim all liability for damage caused by incorrect line voltages!
Check to make sure that the line voltage matches the supply voltage specified
on the identification plate. Deviations of ±10 % are permissible.
400 V / 3 Phases / 50 Hz  Connect the mains power cable (9) to a electricity supply system with
protective earth!
Cable markers:
1 = L1
2 = L2
3 = L3
4 = N
green/yellow = PE
230 V / 3 Phases / 60 Hz  Connect the mains power cable (9) to a electricity supply system with
protective earth!
Cable markers: 1 = L1
2 = L2
3 = L3
gnge = PE
5.6. Filling
Caution:
First connect the external system! See page 23
Use a funnel for filling the system. Spilling bath fluid may result in the fluid to enter the
electronics in the interior of the unit. This must be avoided in any case!
Take care of the bath liquid's changing volume varying with the working temperature of the
Magnum temperature system.
Guideline:
A volume change of 12 % per 100 °C temperature variation is to be considered.
34.5 liters 21.5 liters
Determination of the required total filling volume:
Filling volume of Magnum 91 + filling volume of external system
Filling volume: Magnum 91 without external system
