CAUTION : For continued safety, replace safety critical
components only with manufacturer’s recommended parts
(refer to parts list).
Indicates safety critical components. To reduce the risk of
electric shock, leakage-current or resistance measurements

voltmeter. Values may vary slightly due to variations
between individual instruments or/and units.
