4. Power Connection for RPCM 3x250 and RPCM DELTA
Power Connection 3x250
RPCM 3x250 connections should be made strictly according to the purpose of the terminals.
The assignment of the terminals for connecting the RPCM 3x250 is shown in Fig. 3.
IMPORTANT! The RPCM 3x250 model must be connected in the WYE mode, that is, there comes 3
phase wires and neutral, as well as a protective conductor (protective ground).

Power Connection RPCM DELTA
RPCM DELTA connections should be made strictly according to the assignment of the terminals.
The assignment of the terminals for connecting RPCM DELTA is shown in Fig. 4.
IMPORTANT! The RPCM DELTA model must be connected in the DELTA mode, that is, 3 phase
wires are fed to the device, as well as a protective conductor (protective ground).
