ACM-M-D/IP72 / ACM-M-D/IP96
Connectors and terminals for power and external equipment are
accessible at the rear of the ACM-M-D/IP72 and ACM-M-D/IP96
a inets o a ess t e onne tors o en t e a inet oor an s ing
out the AlphaCom exchange frame.
Cable inlets are at the bottom of the cabinet and there is a cable
fastening bar in the lower part. All internal cabling is ready-made from
the factory and routed in cable conducts.
The number of terminals and physical placement of terminals for

4.5.1
ACM-M-A-V2 / ACM-M-D
The ACM-M-A-V2 and ACM-M-D are powered from 230 VAC mains
with automatic switch-over to 230 VAC UPS or 24 VDC emergency
power.
All internal power cabling is ready-made from the factory and routed
in cable conducts.
Connect 230 VAC mains to L and N terminals on the X1 circuit breaker
Connect mains earth to the ground bar
Connect 230 VAC UPS power to L and N terminals on the X2 circuit
breaker if this backup power is used
Connect 24 VDC emergency power to the + and - terminals on the
X3 circuit breaker if this backup power is used
The 230 VAC mains outlet X7 is used for service purposes.

Power failure
Three power fail relays are included to indicate the types of failures. Each
relay has a NO/NC switch-over contact to indicate ‘Power good/fail’. The
relays are a ti ate
en t e a tual o er is
i means t at t e
NO contact is closed and NC is open under normal conditions.
- X4 is released if the 230 VAC power fails (mains and UPS)
- X5 is released if the 24 VDC emergency power fails
- X6 is released if the 24 VDC output power from AMC-XE7 fails
