Connecting to Main Power (AC Models)
Before you Begin
lAMC AC controllers are intended to be supplied in Europe by AC power with a 16A rated over cur-
rent protective device and 2 poles disconnecting device (circuit breaker) or with 20A over current
protective device and 2 poles disconnecting device (UL 489 circuit breaker) in the US and North
America. This device is to be suitably located and easily reached and marked as the disconnecting
device for the equipment. The circuit breaker shall meet the requirements of IEC 60947-1 and IEC
60947-3 and be suitable for the application.
lUse only the built-in transformer.
lIn case the controller is supplied with a power supply cable connected to it, the controller is for
indoor installations only!
lPower supply cable should be Outdoor rated, suitable for the installation site, and should comply
with IEC 60227 or IEC 60245 for Europe or ANSI/UL 817 and CSA C22.2 No. 21 for USA and Canada.
lPower supply cable rating: 250VAC, 1A: -30°C ~ +120°C or 115VAC, 1A: -30°C ~ +120°C depends on
the controller’s actual model.
lPower supply cord cables yellow and green are for ground connection only.
lIf the supply cord is damaged, it must be replaced by the manufacturer or service agent or a sim-
ilarly qualified person in order to avoid hazard.
lIn order to use the controller for outdoor installation, a licensed electrician must disconnect the
power supply cable, and connect the controller according to the instructions given in the install-
ation chapter of this document and in compliance with all the safety instructions and the local
standards for High Voltage out-door connection.
lIn order to use the controller for outdoor installation, a licensed electrician must disconnect the
power supply cable, and connect the controller according to the instructions given in the install-
ation chapter of this document and in compliance with all the safety instructions and the local
standards for High Voltage out-door connection.
lIf the plug doesn’t comply with your local regulation it must be replaced with suitable plug by
licensed electrician only. Please note that opening additional cable holes in the controller’s housing
bottom plate should be done by drilling only and not by hammering the knock-outs!
lIt is necessary to connect a two-pole switch between the power supply and the controller 115VAC
or 230VAC (depends on the actual controller model).
lThe supply point 115VAC or 230VAC (depends on the actual controller model), the circuit and con-
nection to the transformer must be performed according to “Field Electrical Regulations” by a
licensed electrician who is accredited with a license according to the Electrical Bill and security
requirements.
lWhen using an internal transformer, minimal wire diameter must be 0.7mm. Check with standard
measuring equipment that there is no voltage in the electric circuit.
Connecting to Power
1. Route an AC power cable through the cable gland at the bottom side of the cabinet.
The cable range should be Ø4-Ø7 mm.
2. Connect the wires to the transformer wires located inside the cabinet. The Controller units are
supplied with a built in terminal strip.
See "Terminal Strips Drawings" on page11 for wiring diagrams.
