Electrical installation
Connecting the supply voltage
When wiring the interrogator using connection module CDB620 or CDM420, the interroga-
tor's data and function interfaces are contacted to the connection module together with the
power supply.
1. Ensure that the connection module's supply voltage has been switched off.
2. Standard version: connect the bar code scanner's 15-pole cable plug to the connection
module's 15-pole socket and screw it tight.
- or -
Ethernet version: connect the interrogator's 12-pole plug via a corresponding cable
(e.g., no. 2042916) to the connection module's 15-pole socket and screw it tight.
