Power Connection
The 6-pin terminal block on the bottom panel contains connectors for two DC power inputs. Each is indicated
with polarity signs, as shown.
The GLM Switch may be powered from one or both power inputs. The specified voltage range is 12Vdc–58Vdc.
The 6-pin terminal strip will accept AWG 28~14. The wire should be stripped back 6~7mm. The screw torque
limit is 2Nm.
The P1 and P2 LEDs on the front panel indicate the status of these two power supply inputs, as shown in
Section 3.6, LED Operation.
GLM Switch Current Draw
The maximum current draw at 24Vdc (nominal) for each of the devices is shown below:
Note:
Each DC power input should be connected to a suitably-fused power supply.
