General Tolerances of the Panel and Printed Circuit Board

The cumulative tolerance must not exceed 0.3 mm / 0.012 in: T1 + T2 = 0.3 mm max.

Installation Precautions

Minimum thickness of circuit board: 1.6 mm / 0.06 in.
Cut-out diameter: 22.4 mm ± 0.1 / 0.88 in. ± 0.004
Orientation of body/fixing collar ZB4 BZ009: ± 2^°30’ (excluding cut-outs marked a and b).
Tightening torque of screws ZBZ 006: 0.6 N.m (5.3 lbf.in) max.
Allow for one ZB4 BZ079 fixing collar/pillar and its fixing screws:
- every 90 mm / 3.54 in. horizontally (X), and 120 mm / 4.72 in. vertically (Y).
- with each selector switch head (ZB4 BD•, ZB4 BJ•, ZB4 BG•).

The fixing centers marked a and b are diagonally opposed and must align with those marked 4 and 5.
