CURRENT MONITORING RELAY INSTALLATIONS AND
CONNECTION
These settings are initial and may require changing. Relays must always be
adjusted in a case-specific manner.
1. Choose correct current range
• Turn switch 2 to position ON (if master fuse size is less than 50 A)
• Other switches 1, 3-6 to position OFF.
2. Adjust hysteresis, current % and delay using screws in the front part (mas-
ter fuses 25 A)
• Hysteresis 21
• Current 25 - 28 %
• Delay 1s
• The relay requires external voltage 24-240 V/AC.
• External supply is connected to terminals A1 and A2.
• Terminals 15 and 16 are connected to geothermal heat pump and inter
rupt the heating element’s supply with respect to the phase the current
value of which is exceeded.
• Each phase must be lead through the relay using the dedicated hole
inside it.
• L1 for relay 1
• L2 for relay 2
• L3 for relay 3
No other connections with relay are necessary.
