CONNECTION:
The RXPDK 21H relay requires a dc-dc converter type RXTUG for auxil-
iary voltage supply +24 V. Connection of voltage RL shall be made only
when the binary input is used.
The relay is delivered with a short-circuiting connector RTXK for mounting
on the rear of the terminal base. This connector will automatically short-cir-
cuit the current input when the relay is removed from its terminal base.
NOTE! The auxiliary voltage supply should be interrupted or the output cir-
cuits should be blocked to avoid the risk of unwanted alarm or tripping, be-
fore the relay is plugged into or withdrawn from its terminal base.
