To completely isolate the unit from the power supply, you must disconnect the power plug. Install the unit
in a way that the power plug is easily accessible and can be easily disconnected in case of danger.
The unit must NOT be installed and operated in hazardous locations.
DANGER
Explosion hazard.
Danger of death.
∅ Do NOT operate the unit in potentially explosive areas.
¾ KEEP explosive dust or air-solvent mixtures AWAY from the vicinity of the unit.
4. Installation of the equipment
4.1 Electrical connection
The Alarm Box AB 01 has a fixed connection cable, 1800 mm in length (4) and a shockproof plug:
• Power fuse 10 Amp
• Power supply 230 V (1N ~ ) +/- 10 %, 50/60 Hz
• Power consumption <20W
• Unit fuse: Fine fuse 5x20mm 10A (M) (5)
• Protection type IP20
• Prior to connection and start-up, check the power supply voltage. Compare the values to the data
specified on the type plate of the unit (chap. 1.3).
•
When connecting, please observe the regulations specified by the local electricity supply company
and as well as the VDE directives (for Germany)
• Pollution degree (acc. to IEC 1010-1): 2
• Over-voltage category (acc. to IEC 1010-1): II
CAUTION
Danger of incorrect power supply voltage.
Damage to the equipment.
¾ Check the power supply voltage before connection and start-up.
¾ Compare the power supply voltage with the data indicated on the type plate.
We recommend taking the electric power from a central alarm facility (as far as existing) with a backed-up
power feeding 230V AC (e.g. battery buffer for PCs). Only then the alarm transmission during a power
failure is guaranteed.
The power consumption of the unit is less than 20 W. Additionally for alarming during a power failure, it
is necessary that the computer on which APT-COM™ 3 or the Watch Tool software is running is also
connected to a backed-up power feeding (e.g. battery buffer for PCs).
To completely isolate the unit from the power supply, you must disconnect the power plug.
Install the unit in a way that the power plug is easily accessible and can be easily
disconnected in case of danger.
