  • Page 28 Introduction Conditions at the place of installation Conditions at the place of installation CAUTION Protect the devices in a desktop housing from moisture and dampness or weather conditions such as rain, snow, etc. Make sure that you do not cover the ventilation openings at the side, the openings for the power pack fan on the back side of the device and the openings underneath the device.
  • Page 29 Introduction Maintenance and cleaning Maintenance and cleaning The MGCplus system devices are maintenance-free. Please note the follow­ ing points when cleaning the housing: CAUTION Disconnect the mains plug from the socket before cleaning. Clean the housing with a soft, slightly damp (not wet!) cloth. You should never use solvents, since this may damage the labeling on the front panel and the display field.

  • Page 33 Connection Connecting the MGCplus in a tabletop housing/rack frame If several MGCplus systems are to be synchronized with each other, each system must be equipped with a CP52 communications processor. To syn­ chronize MGCplus systems with CP52, you need a synchronization cable with the HBM part number 1-KAB2125-2 (2 m in length).

  • Page 40 Connection Shielding design Notice All parts of the measurement chain (including all cable connection points such as plugs and couplings) must be surrounded by a closed EMC-tested shield. Shield junctions must represent a full contact, closed and low-imped­ ance connection. This is the case for original HBM plug connections. Ground connection and grounding As the signal ground and shielding are separated in EMC-compliant cabling, the shielding can be connected at more than one point to the ground, i.e.
  • Page 41 This applies to all bridge connections. When using long cables and with a high transducer resistance, HBK additionally recommends soldering resistors in the sense leads. The resistors should be placed as close as possible to the transducer. The value of the resistances must be half that of the bridge resistance /2).
