Wilo YONOS ECO 25/1-5 BMS - Connector and control cable setup

Installation and operating instructions Wilo-Yonos ECO BMS 31
English
• The electrical connection must be established via a fixed power cable (3 x 1.5 mm
2
mini-
mum cross-section), equipped with a plug and socket connector or an all-pole switch
with a minimum contact opening width of 3 mm.
• The following minimum requirements are to be met if shutdown takes place by means of
an on-site network relay: Rated current ≥ 8 A, rated voltage 250 VAC,
Contact materials: AgSnO2 or Ag/Ni 90/10
• Fuse protection: 10/16 A, slow-blow or automatic fuse with C characteristic.
• A motor protection switch supplied by the customer is not required. Nevertheless, if such
a protection switch is available in the installation, it must be bypassed or set to the highest
possible current.
• Leakage current per pump I
eff
≤ 3.5 mA (in acc. with EN 60335)
• It is recommended to safeguard the pump with a residual-current device.
Labelling: RCD type A or RCD type B
When dimensioning the residual-current device, consider the number of pumps con-
nected and their rated motor currents.
• All connection cables must be installed so that they do not touch the pipe and/or the
pump or motor housing.
• Earth the pump/installation in accordance with the regulations.
• L, N, : Mains supply voltage: 1~230 V
AC, 50/60 Hz, DIN IEC 60038
7.2.1 Installation/dismantling of the Wilo-Connector
• Disconnect the connecting cable from the power supply.
• Observe the terminal allocations (PE, N, L).
• Connect and fit the Wilo-Connector (Figs. 3a to 3e).
• Connect the Wilo-Connector to the mains cable with the connection housing (Fig. 1,
item 6) until it snaps into place.
Dismantle the Wilo-Connector in accordance with Fig. 4. A screwdriver is needed for this.
7.2.2 Assignment of the control cable
NOTE: To ensure interference resistance the total length of the 0-10 V control cable
should not exceed 15m
• 0-10V:
• Electric strength 24V DC
• Input resistance of the voltage input >100 kOhm
The Yonos ECO BMS pump is fitted at the factory with a control cable (1.5 m) for the SSM
connection and 0–10V (Fig. 1, item. 7).
• Wire 1 (brown): GND (signal earth)
• Wire 2 (white): 0...10 V (signal)
• Wire 3 (blue): SSM
• Wire 4 (black): SSM
0-10V SSM
