4. Installation
4.1. General
Mount vertically on a non-flammable surface, with the power terminals facing downwards. Observe a minimum clearance of 10 cm under and above the product for optimal cooling.
Mount close to the battery, but never directly above the battery (in order to prevent damage due to gassing of the battery).
4.2. Connection setup for DC-DC converter mode
Disconnect the remote on/off (remove wire bridge).
Connect the input supply cables.
Open the VictronConnect App to setup the product. (always adjust the output voltage before connecting in parallel or connecting a battery)
Connect the load. The converter is now ready for use.
Reconnect the remote on/off to activate the product.
Figure 1: Typical connection setup as DC-DC converter
4.3. Connection setup for charger mode
Disconnect the remote on/off (remove wire bridge).
Connect the input supply cables.
Open the VictronConnect App to setup the product. (always setup the correct charger algorithm before connecting a battery)
Connect the battery to be charged.
Reconnect the remote on/off to activate the product.

4.4. Connection remote on-off
The recommended use of the remote on-off is:
a) A switch wired between the L-H pins (On-level impedance between L-H pins: < 500kΩ)
b) A switch wired between (input/starter) battery plus and H-pin (on level: > 3V)
c) A switch between the L-pin and (input/starter) ground (on level: < 5V)
d) Isolated remote on-off cable e.g. controlled by a (small)BMS
Notice
Voltage tolerance L & H pin: +/- 70VDC
a) L-H pin wiring | b) H-pin wiring | c) L-pin wiring | |
d) Isolated remote on-off cable | |||

4.5. Engine shutdown detection override
In charger mode the “engine shutdown detection sequence” determines if conditions are met to enable charging, see chapter 5. The “engine shutdown detection override” forces the charger to allow charging independently of the engine shutdown detection. Engine shutdown detection override is activated by applying >7V to the remote L-pin. This allows external control (e.g. ignition switch, CAN bus engine on detector) to enable charging.
Notice
This function does not override the remote on-off function. Remote connection a), b) or d), as shown in Figure 3 must be configured in combination with engine shutdown detection override. See examples in figure 4.

Figure 4: Engine shutdown detection override connection diagram
Note
If the ignition switch in figure 4 is switched off, the charger will return to “engine shutdown detection” mode, it will not turn off the charger.
To force enable/disable charging (i.e turn the ORION on/off) without the “engine shutdown detection” a remote option as given in chapter 4.4 must be wired, and the engine shutdown detection must be switched off in VictronConnect, see figure 5.
Figure 5: Disable engine shutdown detection
Warning
When the engine shutdown detection has been switched off in Victron Connect (‘forced charging’) current will be drawn from the starter battery even if the engine is not running.
Note
During ‘forced charging’ the input voltage lockout is the only limit left to disable charging automatically, make sure this level is not set too low, in most applications 12.5V is sufficiently low.
