3.4 Installation Wiring
3.4.1 Pump Cabinet Wiring
The dispenser requires constant 240 VAC to operate. The Pump Cabinet comes with a pre-installed 2.7
meter (9-foot) electrical cord. An appropriate electrical plug must be installed on the cord.
A main switch (EBS Nr. 10010657) or non symmetric plug is mandatory. This will avoid changing the
polarity, because some internal wiring is not subjected to 230 VAC, as it is for 110 VAC only.
Brown – line
Blue – neutral
Yellow/green – ground
Do NOT use power from a laundry machine to operate the dispenser.
This dispenser must remain powered constantly. Do not use outlets that may be shut off manually (GFI outlets are OK).
If the electrical cord can not be used, you must use a minimum cable wire of 14 gauge.
If a condition exists where the cord cannot be used (for example, distances greater than 2.7 meters) the
following procedure should be used.
1. Remove the existing BROWN and BLUE wires off of the terminal posts on the back of the ON/OFF circuit
breaker (BROWN is hot, BLUE is neutral).
2. Remove the GREEN wire with the YELLOW tracer from the ground lug (GREEN is ground).
3. Remove the 2.7 meter power cord from the Pump Cabinet.
4. Field wire a new HOT, NEUTRAL and GROUND WIRE within the Pump Cabinet.
5. Attach the HOT and NEUTRAL wires to the terminal posts on the back of the ON/OFF circuit breaker.
Use the same polarity as the cord installation. Brown is hot, blue is neutral.
6. Attach the GROUND wire to the grounding lug located on the front of the electrical box.
3.4.2. RS-485 Communication Cables
Each module has two communication ports (6-position white connectors). They are identical and completely
interchangeable. You may connect the communication cables to either port. When making the connection,
ensure the cable snap-locks (audible click) into the connector on the circuit board.
Do not plug or unplug RS-485 cables when power is applied to the system. Do not apply power to the system until all modules are
properly addressed and all RS-485 cables and plugs (dongles) are properly connected to the modules.
