Please ensure you read the paragraph: Special Specifications for use in Potentially Explosive
Atmospheres in Accordance with European Directive ATEX 94/9/EC
.1. Installation: recommendations
The MX52 unit can be installed in any premises without an explosive atmosphere. They should
preferably be placed in a ventilated and monitored location (guardhouse, control room,
instrumentation room, etc.).
Attachment is to be ensured in accordance with the dimensions in Figure 1 (four attachment points).
REMARK
In order to permit the swivelling front panel of the unit to be opened completely, allowance must be
made for opening by rotation through 180° downwards.
Before making any connections, the unit should be switched off using the main On/Off switch
below and to the left of the FRONT circuit (see Figures 4 and 26).
.2. Electrical connections of the MX52 Unit (Fig. 8)
The MX52 unit is equipped with a pulse automatic device which enables to connect 24 V DC
voltage in a lack of 220 V AC voltage so we can use no expansive save power supply.
2.2.1. Alternative power supply
- Voltage: 230 V AC (207 to 244 V) 50/60 Hz
- Maximum power: 300 VA
- Maximum current in cable: 1.5 A
- Cable: 3 x 1.5 mm² (including earth)
- Location of connection terminal blocks: Fig. 8, item A
- Protection: the phase and neutral wires are protected by time-delayed 2 A
fuses located at the rear of the power module.
- Voltage: 103 to 122 V AC - 50/60 Hz on option
CAUTION
It is mandatory that the appliance must be earthed. A terminal is reserved for this purpose at the
back of the power module: see Fig. 5. This connection is required in order to ensure correct
operation of the following:
- mains power interference filter,
- protective devices against electromagnetic interference.
