Notes on the electrical installation
Electrical connections between the RFH630 and other devices may only be connected
or disconnected when the system is not live, otherwise the devices may be damaged.
Do not switch on the supply voltage for the RFH630/the CDB620-001 connection mod-
ule until the connection work has been completed and the wiring work has been tested
thoroughly.
Prerequisites for enclosure rating IP 67
The cover for the Micro SD card slot has to be screwed onto the housing during normal
operation.
Protect the RFH630 from moisture and dust when the cover is open.
The electrical connections of the RFH630-1102101 not used have to be fitted with pro-
tective caps/plugs.
The same also applies for the EMC requirements (ESD) according to CE.
Cable lengths
The possible length of cable between RFH630 and the host computer depends on the
selected physical design of the host interface and the set data transmission rate. For the
serial interfaces, see
Chapter 3.6.4 Wiring serial data interfaces, Page 23
