General operation
Wire table
| Wire | Standard function |
|---|---|
| Red | +Vdc continuous supply |
| Black | Ground |
| Brown | +Vdc pulse closes contact |
| Orange | +Vdc pulse opens contact |
| Yellow | Status (LED) output |
¹⁾ The Status output is a ground referenced open collector port with a maximum
switching capacity of 60V / 100mA (Rout ≈ 10 Ω)

Contacts are welded, replace RBS| Contact fails to open. Check if
supply voltage is within range.
Otherwise return RBS for
service.| Contact fails to close. Check if
supply voltage is within range.
Otherwise return RBS for
service.
Change control mode
When in off mode, press all three buttons simultaneously for three seconds to
enter the setup mode:
Step through the control modes by pressing the OPEN (up) or CLOSE (down)
buttons
Control mode table
| Mode no. | Open LED | Close LED | Control mode |
|---|---|---|---|
| 1 | 2-wire, no contact change at power-up | ||
| 2 | 2-wire, contact closes at power-up | ||
| 3 | 2-wire, contact opens at power-up | ||
| 4 | single-wire, normally open contact | ||
| 5 | single-wire, normally closed contact |
= LED off
= LED green
= LED orange
When the desired control mode is selected, press the Power button for 2
seconds to save the setting.
Press the Power button again for 2 seconds to activate the RBS with the new
control mode.
Modes 1, 2 & 3: +Vdc pulse on brown wire to close, +Vdc pulse on orange wire
to open.
Mode 4: +Vdc continuous on brown wire to close, 0Vdc on brown wire to
open. Orange wire not used.
Mode 5: +Vdc continuous on brown wire to open, 0Vdc on brown wire to
close. Orange wire not used.
Installation details
Precautions
- Please install this product in a dry indoor location, as close as possible to the battery. To be installed only by qualified technicians.
- To avoid fire hazards, use correctly sized cables which are suitable to carry the expected load currents in your application. The maximum continuous RBS current rating of 500A is only valid when a total cable size of at least 200mm2 is connected to the M10 studs. Or when the RBS is part of a DC Modular system containing large busbars and fuseholders.
- To avoid fire hazards or damaging the RBS, please make sure that all nuts are securely tightened. Please apply our recommended torque rating of 22Nm for the M10 nuts.
- To avoid fire hazards or damaging the RBS, please make sure that spring- and flat washers are always placed directly below the nut. Never place washers between: busbar and cable lug, multiple cable lugs on the same stud, busbar and linkplate or cable lug and linkplate.
- Please make sure that all connection cables are properly strain relieved, to avoid excessive mechanical stress on the RBS.
RBS features
- Smart high current magnetic latching relay, draws virtually no current in On (Close) or Off (Open) state.
- Silver alloy contacts and silver plated copper busbars, for maximum conductivity and high reliability when switching live loads.
- Local Open and Close buttons on top, to manually override the switch state.
- 5 wire interface cable for external control by panel switch, battery monitor or BMS. Compatible with two wire or single wire
- On/Off control. Includes status wire for controlling indicator light or providing feedback to BMS.
- Stainless steel studs, washers and nuts for optimal corrosion resistance.
- Unique grid optimized footprint allows space saving arrangements with other DC Modular products.
- Special fiber reinforced plastic housing offers excellent high temperature properties, good chemical resistance and high strength.
- Robust transparent covers with breakouts to allow wire access from any direction.
- Smart terminal design allows dual mirrored cable lug connections.
