Mains
Connect the mains power to the MAINS input of each DCA2.500 amplifier/charger. Keep the right polarity
and connect the protective earth wire to the ground terminal.
•
Mains connection must be connected in a permanent way to the mains network of the building;
•
The external circuit feeding mains input of the Impact system must be equipped with an automatic
overload protection and automatic earth-leakage protection.
•
Mains circuit must include main rack circuit breaker of following rating:
o
No of DCA2.500 <10: 40A
o
No of DCA2.500 >10: 63A
Mains circuit breaker must be located in the circuit at the rack entry, before splitting to the
DCA2.500 units;
Recommended mains circuit breaker type:
ABB SD 202/63 or equivalent.
Caution! Be careful! Risk of electrical shock! Make
sure that the mains cable is not connected to the
electricity network during equipment installation.

Battery
Use only valve-regulated, sealed lead-acid maintenance-free batteries for stationary use. The Impact system
is designed to operate with 24V battery (2 x 12V DC nominal voltage).
To safely and properly install the battery circuit, follow the instructions below:
1.
Before installing the battery, measure the voltage of each battery separately. The open-circuit
voltage of a well-functioning, healthy 12V battery should be in the
11,5 V – 13,5 V
DC range. If the
open-circuit battery voltage is out of this range, replace the battery. Always use pairs of batteries
with the same open-circuit voltage (as close as possible).
2.
Adjust the battery position in the rack to make enough room for safe installation (preferably
bottom of the cabinet).
3.
The DCA2.500 is equipped with internal battery fuses. However, for extra safety and convenience,
it is recommended to use an additional removable battery fuse for each DCA2.500 amplifier (40A,
slow).
4.
Caution! Be careful! The negative pole of the battery connector is connected directly to the ground
potential and the entire metal housing of the Compact 500. Dropping an unprotected battery lead
on any part of the hardware, housing or battery brings a high risk of short-circuit and may damage
the hardware and the battery. The high electrical current from the battery when short-circuiting
may cause a rapid battery discharge and instant heat production. This may also destroy hardware
components, cause serious battery capacity degradation or battery damage, cause fire and may
be a potential risk to your health.
