Electrical Connection
English
Please observe your local technical connection requirements.
With a fixed connection thermust be an all-pole head release devise connected in series with at least 3 mm clearance between
it and the device. This requirement is met with circuit breakers for example.
For start-up see the following page.
Reinsert the front and side panels and fasten the screws. Reverse dismounting procedure.
15. Carry out the electrical connection to the terminal strip of the device.
Connection example: With heating contactor and wall-mounted thermostat.
