High Leakage Current - Seeley Climate Wizard CW-80 Installation & Operation Manual

INSTALLATION cont.
CW-80T-TWIN Electrical Supply Specification:
Standard: 380 - 415V / 50Hz / 3 Phase / 44A
High Capacity: 380 - 415V / 50Hz / 3 Phase / 54A
Mains power terminals are provided inside the mains
isolation switch which is mounted on the central area of
the chassis beam for electrical supply connection.
With the 2 CW-80T's positioned together to create a CW-
80T-TWIN, there is a requirement to connect the supply
power of the 2 units. Extra cable and conduit has been
supplied to achieve this.

Once cable is connected, conduit can be glued into the
connection fitting using solvent cement. Supplied "P"
saddle clamps can be riveted to chassis beam to safely
retain the conduit in position.

High Leakage Current

WARNING: High Leakage current
The CW-80 family of coolers utilises fan motors with built
in inverter drives. To comply with EMC regulations, these
drives adopt EMC filters that connect to the motor earth
terminals. Across a total of 6 fan motors, the normal filter
leakage current to earth accumulates to a total leakage
current in excess of 10mA.
To comply with regulations and to prevent electric shock,
this leakage current must be properly addressed.
In particular, both earth terminals (PE1 and PE2) at
the mains power point of connection must be properly
connected and earthed. Power must not be applied until
this is correctly completed.
Further, being a safety issue, warning labels (as below)
have been installed inside the electrical enclosure door
(middle picture) and also adjacent to the incoming power
cables (bottom picture).
