5. INSTALLATION INSTRUCTION OF WTC/4…C../EX ● For WTC/4…C../EX platform scales prepare an appropriate place for installation. It should be dry, even and rigid. Acceptable operation temperature range -10°C to +40°C. The ground on which the platform is to be placed must be able to carry the maximal load together with the platform. - Page 10 The way of earthing is shown below ● Weighings platform should be placed on an even, stable ground far from sources of hit and draughts. Use an external large size level indication device to level the platform. Use levelling feet to regulate the level. - If levelling is necessary proceeded as directed below: ○...
- Page 11 Before the first start make sure that there is no danger of explosion (no explosive gases). If there is any sign of inappropriate operation the scale should be unplugged from the power source and then move the device to the safe area for temporarily storage to prevent it from using until it is repaired.
